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

eclipse.buildId=4.35.0.I20250113-0634

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.

[RyoObayashi]

Using a self-signed certificate to install the plugin might not have been a good idea.

[jdneo]

Hmm, might be a reason.

I'm wondering why cannot install from marketplace. What error did you see when you drag it into eclipse?

[RyoObayashi]

I'm sorry for the late reply. Here is the initial error that occurred.

https://azuredownloads-g3ahgwb5b8bkbxhd.b01.azurefd.net/github-copilot/content.xml のリポジトリーを読み取ることができません。

[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

[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?

[jdneo]

We are now working on chat. Highly likely model switching would come after that.

[chungpham40]

Cảm ơn bạn

[rberlich]

Ok, just to reconfirm: chat is not available yet, i.e. I cannot give it a prompt to create some function, and it can "only" do code-completion?

[jdneo]

@rberlich Chat is not available now. We plan to support chat in March.

[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.
class com.sap.adt.cds.ddl.ui.internal.editors.pages.DdlSourcePage$2 cannot be cast to class org.eclipse.jface.text.ITextViewer (com.sap.adt.cds.ddl.ui.internal.editors.pages.DdlSourcePage$2 is in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @6df7b3c6; org.eclipse.jface.text.ITextViewer is in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @681c6964)

[jdneo]

ABAP is something we are looking into recently. Please stay in tune.

[sudantha]

Hi Sheng @jdneo , Thank you very much for building this add on !! ,Adding more to @MARCxGAMBIT , we are really interested to see this work for ABAP language as Eclipse is used in ABAP development in so called "ABAP Development Tools" , We were working ABAP with VSCode and it was giving some great results in code generation and fixes.

[sudantha]

I tried with ABAP Cloud version but it doesn't give any code suggestions or neither any runtime errors , I hope currently this add on only works for specific program languages ?

[ethanyhou]

Hi @sudantha & @MARCxGAMBIT ,

Thanks for the feedback. Due to the special nature of the Eclipse ABAP environment (ADT), the current GitHub Copilot plugin version does not support it yet. We are actively working with SAP to fix this issue ASAP and will let you know once it is supported.

[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.

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

[kwin]

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

[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.

[jdneo]

@sulranjan Seems that the image you've attached is broken

[OxSoadyp]

eclipse 2024-12, copilot 0.2.0 Icon says status ready. Logged in.
No completions are suggested.
No errors. Nothing .
Any ideas ?

I think it may be an in compatibility with SAP ADT tools.

eclipse Version: 2024-12 (4.34.0) Build id: 20241128-0757
ABAP Development Tools Version: 3.48.0

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 @17b9c072; org.eclipse.jface.text.ITextViewer is in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @16f75247)

[jdneo]

Sorry, we have some issues on ABAP support and is engaging with SAP to solve it now. Please stay tuned.

[sudantha]

Hi @OxSoadyp , I'm having the same issue , as per @jdneo ADT Tools are not yet supported

[OxSoadyp]

out of interest is that an issue with regard to how sap manage their plugin ?
Or is that just a new case for the Github CoPilot ?
anyway. Good to know you are on it. THX.

[jdneo]

Seems that it's related with the implementation of the copilot plugin. We are investigating.

[markgoodchild]

Firstly thank you for the release of this plugin. We are very interested in enabling its use alongside our Eclipse based products. :-)

Trying to install the GitHub Copilot plugin in Eclipse.
We are struggling to install this reliably, I wondered if you could help or consider some improvements.

We have noticed two things:

For the annotation plugin issue:
Install fails with Software being installed: GitHub Copilot 0.2.0.202502180149 (com.microsoft.copilot.eclipse.feature.feature.group 0.2.0.202502180149)
Missing requirement: com.microsoft.copilot.eclipse.core 0.2.0.202502180149 (com.microsoft.copilot.eclipse.core 0.2.0.202502180149) requires 'osgi.bundle; org.eclipse.jdt.annotation 0.0.0' but it could not be found

In our view the org.eclipse.jdt.annotation plugin dependencies should be marked as optional, so they are not required at runtime. Those annotations are only used at build time so not expected to be present in an installation. I think many Eclipse based products might fail with this error.

For LSP4E

Software being installed: GitHub Copilot 0.2.0.202502180149 (com.microsoft.copilot.eclipse.feature.feature.group 0.2.0.202502180149)

Cannot satisfy dependency:

I think the plugin should clarify the minimum supported Eclipse version or it needs to relax the LSP4E dependency to allow earlier versions if the plugin is not using older API. If it is using the newest version of the LSP4E API then OK. I do see the Eclipse pre-requisite version is 2024-09.

[jdneo]

Thank you for the suggestion. I agree that we should change it to optional.

I think the plugin should clarify the minimum supported Eclipse version or it needs to relax the LSP4E dependency to allow earlier versions if the plugin is not using older API. If it is using the newest version of the LSP4E API then OK. I do see the Eclipse pre-requisite version is 2024-09.

The reason that we require 2024-09 or higher is because we are using the code mining api to render the inline completion, and the support for multiple line rendering was introduced in 2024-09.

lsp4e@0.18.12 is the version of 2024-09. But yes, I agree with you that we should check if we can lower the version if we are not using any new apis.

I've tracked the two suggestions into our issue board. Thank you for your feedback!
