On very first time I start typing in the code I always get this error below:

Looks like com.microsoft.copilot.eclipse.core.completion.CompletionProvider$CompletionJob.notifyCompletionResolved() doesn't expect that ContextService.activateContext() call it does from the job will need UI thread access.

[jdneo]

Hi @iloveeclipse, thank you for the feedback.

Seems that we need to wrap the calling of ContextService.activateContext() to the UI thread.

One question: I tried to reproduce it locally but not success. Is it related with specific eclipse version?

[iloveeclipse]

Hi @jdneo , yes, I was using 4.35 nightly build. You can try with this one, which will be 4.35M3: https://download.eclipse.org/eclipse/downloads/drops4/I20250213-1800/
I can also fix it by myself if you give me access to the code.
See https://accounts.eclipse.org/users/aloskutov#tab-projects

[jdneo]

We've fixed this issue on our end, will let you know if we will release a patch containing the fix. Thank you!

[jdneo]

@iloveeclipse 0.2.0 is released with the fix for this issue. Pls let us know if you can still see the exception. Thank you!

[iloveeclipse]

@jdneo : thanks, so far haven't seen it again with 0.2.0 version. Great!
Next goal: sort out the problem with multipage editors I've reported below :-)

[iloveeclipse]

It seems that every AI interaction / code proposal is logged to the Eclipse Error log as "Info":

Logging is fine, but that pollutes application log with lot of "garbage". Ideally this would be redirected to a dedicated log file and only warnings/errors are printed to the main log file.

[jdneo]

Tracked the issue in our list. Thanks for the suggestion. 👍

[bhavesh4321]

Not working for me :-(

[ethanyhou]

Hi @bhavesh4321 , may I know what issue are you facing?

[hieplq]

I bring my report to here

This message still appears multiple times even after I dismiss it.

comment from ethanyhou
Hi @hieplq ,

Thanks for the feedback. Could you please let me know if the dialogue appears multiple times when Eclipse starts up, or does it occur every time you type a character on the keyboard?

[hieplq]

This message appears on a timer (about every few minutes) and can create duplicates if you don’t dismiss the previous one.

[ethanyhou]

Hi @hieplq,

After investigation, this is a server-side feature despite the IDE environment. You can log out of the plugin and log back in once your quota is refreshed as a workaround. We will also try to improve the user experience in future releases. Thanks for your feedback!

[RyoObayashi]

There are several errors. This is part of them.
What can I do? I'm not familiar with Eclipse, and I apologize if this is a silly question. Thank you.

What I did:
I couldn't install the plugin from the Eclipse Marketplace, so I added the certificates using keytool. I used the following commands:

keytool -import -alias server-cert1 -file "C:\pleiades\2024-12\java\21\lib\security\azuredownloads-g3ahgwb5b8bkbxhd.b01.azurefd.net.crt"
keytool -import -alias server-cert2 -file "C:\pleiades\2024-12\java\21\lib\security\copilot.microsoft.com.crt" -keystore "C:\pleiades\2024-12\java\21\lib\security\cacerts" -storepass changeit

The installation was successful, but the error occurred.

[ethanyhou]

Hi @RyoObayashi ,

Could you please follow this solution to see if it can be downloaded?

Another solution is you can favorite the GitHub Copilot plugin, then go the eclipse's embedded market place, then click 'Favorites' tab and signin with your eclipse account. You will find the GitHub Copilot plugin there and it can be installed to eclipse directly without dragging from browser:

[RyoObayashi]

My issue is not that I cannot download the plugin, but that the downloaded plugin does not work.
Using the linked solution, I was able to download it by loading the certificate myself, but it does not function properly.
I am facing exactly the same problem as N1k145

[RyoObayashi]

My issue was completely resolved by including the following in the eclipse.ini file:
It may also help other users experiencing certificate-related errors.

-Djavax.net.ssl.trustStoreType=WINDOWS-ROOT

[jdneo]

@RyoObayashi Thanks for sharing!

[iloveeclipse]

What is a license restrictions on the bundle? Can it be redistributed with a commercial Eclipse RCP application?

[ethanyhou]

Hi @iloveeclipse , thanks for the suggestion. We are working on the license redistribution for the app and the license will be updated in the future release.

[ethanyhou]

Hi @iloveeclipse , the license has been updated to Commercial - Free. Thanks for the feedback.

[iloveeclipse]

@ethanyhou : thank you. Can you please give a link to the license file used?

[jdneo]

@iloveeclipse Just got the reply from our legal team that the terms do not restrict redistribution.

You can find it here:

[kwin]

Please bundle per OS/architecture, currently com.microsoft.copilot.eclipse.core_0.1.0.202502101332.jar is 130 MB, the biggest parts in it being the language server binary which is embedded 4 times

1. mac aarch64
2. mac x86
3. linux
4. windows
   (each being around 50 MB).

The p2 tooling allows you to have architecture specific bundles.

[kwin]

See https://help.eclipse.org/latest/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fmisc%2Ffeature_manifest.html -> plugin->os and plugin->arch

[jdneo]

Thank you @kwin!

This is exactly something we want to do!

[kwin]

When will it be possible to switch the underlying models?

[iloveeclipse]

@ethanyhou : I've tried v0.3.0 now on RHEL Linux 9.2 / Eclipse 4.35 / Java 21, chat view seem mostly work, however the upper half of the chat area doesn't properly repaint, you can see it here where I've resized view few times:

I don't see any errors in the log...

[kwin]

Thanks for the update, I find the UI a bit confusing (at least on Mac OS). It is not clear where the input prompt is at first glance. You should make that more obvious. It doesn't look like any other default input fields...

[ethanyhou]

Hi @kwin, I've notified our designer to redesign the text input area and we will improved the chat view UI in the future releases. Please feel free to let us know if there are any other concerns.

[ethanyhou]

Hi @iloveeclipse ,

It seems like this is an Linux specific issue. We will address it and keep you updated. Thanks for your patience.

cc @jdneo

[totomomo18]

I don't think the Ui being confusing is a only a Linux issue I work with windows and it is the same thing like Kwin said " It is not clear where the input prompt is at first glance. You should make that more obvious. It doesn't look like any other default input fields."

[MARCxGAMBIT]

I am using Eclipse 2024-12 (4.34.0) to develop in an SAP environment. I have installed the Copilot plugin today.

As soon as I open source code (ABAP class, RAP behaviour, Service definition, Table definition) I am getting the following error:

An error has occurred. See error log for more details.
class com.sap.adt.tools.abapsource.ui.sources.editors.AbapSourcePage$OutlineTextOperationTarget cannot be cast to class org.eclipse.jface.text.ITextViewer (com.sap.adt.tools.abapsource.ui.sources.editors.AbapSourcePage$OutlineTextOperationTarget is in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @7bbaf968; org.eclipse.jface.text.ITextViewer is in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @681c6964)

And when opening CDS views I am getting a similar error:

An error has occurred. See error log for more details.

[DaveBSydney]

Thank you @ethanyhou for this. But can we PLEASE have access to a downloadable archive file for local installation. As mentioned before our network blocks the usual jar file download process. This would be greatly appreciated.

[hangwan97]

@MARCxGAMBIT GitHub Copilot for Eclipse now supports ABAP: https://devblogs.microsoft.com/java/introducing-abap-support-in-github-copilot-for-eclipse/

[ethanyhou]

Hi @DaveBSydney ,

As I replied in your main post, you can download it here.

[DaveBSydney]

Thanks so much @ethanyhou

[MARCxGAMBIT]

@ethanyhou @hangwan97 after upgrading to Copilot 0.4.0 my Eclipse (2024-12) refused to launch. Haven't had the time to reproduce this so I am not sure if it's related to the specific Eclipse version or maybe another plugin I am using. I did a clean install of 2025-03 and now Copilot is working 😍

[iloveeclipse]

We see errors while typing ESC key in our multipage editors, coming from

Note: this also happens if the "Automatically show inline completions" option is off, which is yet another issue (I would assume DiscardSuggestionHandler shouldn't be active in this case).

[jdneo]

Thanks for reporting! I'll track this issue in our repo. I think I can apply the completion available context to the discard command to avoid this issue.

One question, what is multipage editors. Is there steps to reproduce this issue so we can verify the fix?

[iloveeclipse]

Yes, and sorry it took time to answer.
Create a new Plug-In project with default wizard, in the opened MANIFEST.MF file go to the MANIFEST.MF tab and hit ESC key.
With Eclipse 4.35 M3 build and latest copilot 0.2.0 version I see this error reported to the log:

I've noticed that it is important that the bug appears only if the multipage editor is opened with non-text page first. If the multipage editor opened and the active tab is a text editor, everything is fine. So it seem that the copilot contribution that hooks into the editor open event miss the tab change in multipage editor.

[jdneo]

Is there a listener interface when switching tabs in a multi page editor?

[iloveeclipse]

I guess few possibilities, depending on what your code is doing.
Let assume you have listener that reacts on part opening and does something with the part. It could ask if the part is instanceof MultiPageEditorPart and then add org.eclipse.ui.part.MultiPageEditorPart.addPageChangedListener(IPageChangedListener) to it.

[jdneo]

Thank you we will take a look.

[N1k145]

It seams like the "Enable Strict SSL" configuration is only working for the java part and not the language server

I can't get completions behind our company proxy even after deactivating the SSL Check

[N1k145]

None at all.

From my understanding your application as two parts, the eclipse integration and a Language Server.

I can sign in when I disable the "Strict SSL" but I can't get completions.

From my perspective is the sign in handled in the Java Part of your Appl. and the Completions come from the LS in TS.

I have seen this error message already in a similiar fashion and the issue was that the TS component does a certificate check that is not that straight forward to decativate. And I have the feeling that your checkbox does not configure the LS but only the sign in.

[yanshudan]

Hi @N1k145 , could you please send related language server logs to us? Here are the steps:

• Window->Preference->Language Servers->Logs
• Enable log to file for Github Copilot Language Server
  
• Restart Eclipse, reproduce your issue
• Find the related logs containing signinInitiate and getcompletions in log file(You can find the file location in the screenshot above)
  

[N1k145]

@yanshudan
I did try it first but did not get the sign in the log, so I did log out and in again and have now the issue like you expected it.
I think the previous login was maybe shared from another IDE or the older Unofficial Copilot Plugin from GenuiTec

It looks like you have StrictSSL enabled. Could you please check if there are any entries like this in the log?

[N1k145]

Yes there is a log message like this and the checkbox is not set:

I still claim that the strictSSL is not handled correctly by the LS

[totomomo18]

It is great the Github Copilot decided to officially support Eclipse. I have tried it on my Sts and the completions of code works fast
but why not Chat option ? Please keep working on it give it a Chat , A multi model select, The ability to create new file not just copy code in the editor and maybe someday to ability to have add/edit multiple files in a single prompt in the chat

[jdneo]

Our plan is to release those features progressively. Chat is exactly the next one. Pls stay in tune.

[totomomo18]

I can not wait thank you. Eclipse despite being a great ide unfortunately became the black forgotton sheep of ides
and it desperately need a modern Ai code asstient plugin.
An advance Ai Code Asstient in Eclipse could bring people back to this great Ide

[ethanyhou]

Hi @totomomo18,
We just release GitHub Copilot v0.3.0 for Eclipse to support chat with Copilot. You can update the plugin via Eclipse marketplace and give it a try.

[totomomo18]

Awesome It looks good thank you. but why don't I see Claude Sonnet 3.7 as a model to choose. I can understand that I don't see it if I log with an account that is on the free tier but I am logging with a paid user that should have an option of Sonnet 3.7. Copilot4Eclipse who uses your subscription does that. Is this a bug or is this by design ? Also could you tell what could be the next upgrades and when do you except them to come out ? may I suggest you add to option to create a file on the project from the answer on the chat or to apply the change on an existing file. maybe someday you will have multi files edits and creations in Eclipse

[jdneo]

We are trying our best to launch Claude 3.7 ASAP.

Long story short, currently those newest models will launch to different IDEs progressively. Copilot4Eclipse can have it because it mimic itself as a JetBrains IDE during initialization, which is a kind of abuse of the protocol.

BTW, we are also considering some work to make all the models can be launched to all ides at the same time in the future. Which can avoid confusion like this.

[kwin]

Any plans to publically expose the sources on GitHub? Usually Eclipse plugins work best as open source 1�7

[nickzhums]

Hi @kwin , thanks for your suggestion! At this moment, we are more focused on improving this product and making the experience as smooth as possible for the users. We will keep the community updated if we explore this option in the future.

[markcurtin]

Hi, does anyone know what the context window is for chat when using Eclipse, is it the same as VS Code and other supported IDEs?

[jdneo]

Hi @markcurtin, would you mind explaining more about what the context window mean?

[markcurtin]

Hi, @jdneo - Following this link, you can see how when using VS Code and GPT-4o you can get a 64k context window (or 128k with VS Code insiders)
https://github.blog/changelog/2024-12-06-copilot-chat-now-has-a-64k-context-window-with-openai-gpt-4o/

I'd like to know the Copilot Chat context window in Eclipse.

[hangwan97]

Hi @markcurtin, the context window was enabled from the server side. As long as a certain model was enabled from GitHub Copilot, its relative context window will be supported by default, normally we don't have additional overwritten from the client side.

[Ninja-mann2]

I would like to thank you for your email. Furthermore, I wanted to clarify something. If I am the one who is responsible for the delays, please confirm so that I can coordinate my work with your team to ensure that things are progressing smoothly for everyone.

I have a possible issue:
We have a shared Linux install and some files like copilot-language-server didn't have group execute permissions on them. I don't know if this was an artifact of my install flow or whether it's a more widespread issue. I did the initial install using the Eclipse Marketplace plugin.

[jdneo]

Thanks for reporting. I unzipped the bundle and confirmed that the permission of the binary is not correct. Seems that some unexpected result from the pipeline. We are investigating it.

[jdneo]

@dgibson66 BTW, did you encounter the issue that the language server cannot be launched due to the permission on your Linux?

[xtianus]

Model selection not working on Eclipse 2024-12 (4.34.0) for windows 10, copilot plugin v0.3.0.202503101046. It worked yesterday (just installed) not today after a PC restart.

[ethanyhou]

Hi @xtianus ,

Could you please try to restart the eclipse? This issue is typically caused by an API call failure during plugin initialization, preventing the plugin from recognizing which models are available from the language server.

[xtianus]

I did restart it without success yesterday, but today it works.

[Timbotech633]

When I started using Github Copilot, I switched to VS Code. I can see that VS Code supports way more possibilities to use Copilot. Is there any timeline when which feature will be enabled within the Eclipse plugin?

[ethanyhou]

Hi @Timbotech633 ,

Do you have any specific urgent feature requirements? We are currently focusing on ABAP language support and improvements to the chat feature.

[Timbotech633]

Thanks for the quick response! :) I am especially looking forward to the custom instruction feature.

[DavidHuebner]

Hi, thanks for providing this great plugin. Installation worked without problems.
A problem we face is that we want to restrict the files begin send to Copilot for reasons of data protection.
Ideally, we can use an exclude list based on filename patterns, similar to the functionatlity in VS Code and other IDEs: https://docs.github.com/en/copilot/managing-copilot/configuring-and-auditing-content-exclusion/excluding-content-from-github-copilot
Any development and timeline in this direction would be highly appreciated.

[ethanyhou]

Hi @DavidHuebner ,

Thank you for sharing your requirements with us.

I will create a task to track this request and prioritize it within our team. At present, GitHub Copilot for Eclipse is still catching up with features already available in other IDEs. With limited bandwidth and a substantial workload, some features may take longer to be released. In the future, if you have any urgent demands, please don't hesitate to let us know :)

We greatly appreciate your understanding and patience.

[dgibson66]

If the team could publish a planned release schedule or cadence that'd really help. It's not so much a reflection of the product/team as allowing us customers to know when to go looking for a drop. In lieu of that, I personally tend to go look a lot more often than I should. Saying, "If we drop it'll be on Tuesday morning" would be great.

[ethanyhou]

cc @jdneo @hangwan97

[hangwan97]

@dgibson66 Thank you for your inquiry about the release schedule. Since the initial announcement of GitHub Copilot on the Eclipse Marketplace, we have received a tremendous amount of feedback, many of which were requesting desired features in the upcoming releases. While we plan to announce the general availability of Copilot Chat in April, we are still actively prioritizing the features in our backlog to ensure the best experience for our users.

[dgibson66]

When I first start Eclipse, I see the following. Once I enter a prompt, it all clears up. Eclipse 2024-12 on RHEL8.

[jdneo]

Once I enter a prompt, it all clears up

Do you mean it will disappear (back to normal) after you typing in the input box?

[dgibson66]

Exactly. My impression is that someone forgot to call repaint/refresh on the widget.

[DaveBSydney]

Can we PLEASE get access to an archive version of the CoPilot plugin? (Install New Software -> Add -> Archive instead of URL). Our work network blocks jar file downloads.

[ethanyhou]

Hi @DaveBSydney ,

We are working on determining the best location for the archive file. In the meantime, to temporarily unblock you, you can download it here.

[iloveeclipse]

I see that every time I'm starting to change some code in the editor, "Info" message is reported to the Error log.
Example message:
[Info] Java format preference cache for my_project_name is updated. key: org.eclipse.jdt.core.formatter.tabulation.size, new value: 4

This message is some debug output of the plugin and shouldn't be reported to the error log.

[Badboyboom]

[Info] Java format preference cache for my_project_name is updated. key: org.eclipse.jdt.core.formatter.tabulation.size, new value: 4

[ethanyhou]

Hi @iloveeclipse , thank you for reporting this issue to us. We will fix it in the coming release.

[DaveBSydney]

Has anyone been able to change the font size in the chat window? None of the settings in Preferences seem to apply.

[jdneo]

Not support yet. Will consider to support that. Thank you.

[fidley]

New version, same issues :) I get this at start of the eclipse. Does not matter if I have any opened editor or not. Seems error handling is not yet done correctly.

After waiting a while and clicking on the status bar button I get second error.

And nothing works.

[jdneo]

Is there any other errors in the error log view?

(Window > Show View > Error log)

[fidley]

I see two others,but not sure if they are connected

[dgibson66]

A "Wait # ms before offering a completion" setting would be greatly appreciated. It's sometimes hard to actually enter a tab.

[dgibson66]

Yes. We have an install that's shared by the team. The language server only has user execute permissions Thanks, Doug Gibson

[antarestrue]

Within a chat session, it is supposed to remember the whole conversation, but it does not.
For example, I ask:
"What's the difference between version 0.4.0 and 0.3.0 of the eclipse copilot plugin?"
"What's the difference between 0.3.0 and 0.2.0?"
Copilot should know I am still asking about eclipse copilot plugin in the second question. In vscode, it knows perfectly, but in eclipse, it does not know at all.
Not sure it is a bug or a limitation?
