GitHub Copilot

the workaround is basically for the connection, which for me is ok. That is setup already, but when trying to use the agent mode on chat, then it gives error : 'Copilot currently does not support URI with scheme: semanticfs'.

The ask mode is ok, it works well.

Hello 

I cannot install the extension by the update site you mentioned

An error occurred while collecting items to be installed

and it goes on.

Could you help me?

Kind regards

In case you have the error bellow just remove the menu from perspective (probably is used too sun).: Window > Perspective > Customize Perspective… > Menu Visibility > Copilot

After that open Window > Show View > Github Copilot > Chat and that will properly initialize whatever is needed.

You can enable the view after.

The issues mentioned by the users here are only with the eclipse based plugin and its AUTH with GitHub.

On my machine, I could get a GHCP chat working on VS Code, with all required authentication.

The same authentication gets stuck somewhere only with Eclipse or Spring Tool suite (or other Eclipse based IDE's - no issues with IntellJ or VS Code)

For example - in eclipse, I have a "Sign in to use Copilot"... 

1. which displays a Device code and navigates to github website https://github.com/login/device,
2. where can i choose my GitHub account and proceed with device authentication.
3. supply/ paste the device code from step 1
4. followed by a confirmation screen ("Authorize GHCP plugin")

5. followed by a success & congrats page 

   But nothing changes on the Eclipse side.  

   If on Eclipse I try "Sign in to use Copilot" again, I get 
    

   Sign in failed: org.eclipse.lsp4j.jsonrpc.ResponseErrorException: Could not log in with device flow on https://github.com/: unable to get local issuer certificate

What could be the issue?

thank you

Hello, 

The agent mode for ABAP language is not working. (The ask mode works well)

Gives error : "Copilot currently does not support URI with scheme: semanticfs" 

Is there a workaround or fix for this issue?

Thanks,

When I try install the github copilot via URL getting this error Error while reading from repository: https://azuredownloads-g3ahgwb5b8bkbxhd.b01.azurefd.net/github-copilot/site.xml.

and when I access the URL directly it gives below error. and Please try to help to sort this out

<Error>

Hello,

is it possible to use the plugin on older Eclipse Versions? As mentioned, we use a distribution which is based on 4.25.0 and it would be great if we could integrate GitHub Copilot in this environment as well.

Thanks in advance.

Hi, 

Is there a workaround or any plans to get the agent mode working for ABAP?

Thanks,

Can anyone help?

Extremely annoying, enough to make me stop using copilot. It seems to be related to some Workspace settings other than copilot but I haven't been able to narrow it down. Clean and/or reinstall of the plugin does not help. Using latest plugin version 0.9.3.202507240902. The only solution I've found is to open a new fresh workspace with minimal configuration, but I have so many Workspace customizations (lombok, maven, JDKs, servers, compiler settings, code formatting, perspectives, views, etc) that it becomes impossible to set everything up again when copilot suddenly stops working for no reason, and I can't tell what configuration setting causes copilot to stop working. Saving preferences and restarting Eclipse with the same Workspace will cause copilot to fail to initialize when it previously worked. All plugins and Eclipse are on latest versions. Additional troubleshooting information would be very helpful from the plugin. We are using (paid/licensed) copilot from Microsoft github.com with development against an internal github server.

Hi, Eclipse 2024-06 (4.32) is listed as a supported version for this plugin. However the installation fails with the message 

Missing requirement: com.microsoft.copilot.eclipse.ui 0.9.0.202507150543 (com.microsoft.copilot.eclipse.ui 0.9.0.202507150543) requires 'osgi.bundle; org.eclipse.e4.ui.css.core 0.14.500' but it could not be found

Version 0.14.500 for org.eclipse.e4.ui.css.core is only available since 2024-09. Does this mean that Eclipse 2024-06 is not supported and the information about Eclipse versions in this page is wrong?

We are facing an issue while using the GitHub Copilot plugin in Eclipse IDE (Version: 2025-03 / 4.35.0).

When trying to use the Open Chat feature or fetch suggestions, we get the following error.

FetchError: unable to get local issuer certificate
We’ve already verified that the root and intermediate SSL certificates are present in the Java truststore.

Eclipse is running the latest version.

Any guidance or update would be appreciated.

I’m trying to install GitHub Copilot 0.8.0.202506180627 into Eclipse 2025-06 (Java EE package) via both the Marketplace client and “Install New Software…” (using the official Azure update-site URL). In both cases the install aborts with:

An error occurred while collecting items to be installed
session context was:(profile=C__Users_XXXXX_eclipse_jee-2025-06_eclipse, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

from any repository.

It appears that the feature JAR com.microsoft.copilot.eclipse.feature_0.8.0.202506180627.jar is listed in the p2 metadata but not actually present on the update site. As a result, Eclipse cannot complete the installation.

Request:
Could you please publish or restore the missing feature JAR (and any dependent bundles) at that URL? Once the artifact is available, the install should succeed via both the Marketplace and manual update-site workflows. Thank you!

getting following error while installing

hello

Please add support for eGovFrame 2024-3, a Korean government framework, in the GitHub Copilot Eclipse plugin.

eGovFrame (e-Government Framework) is an open-source development framework created and widely used in South Korea for building public service systems. The GitHub Copilot plugin for Eclipse currently does not support the latest version, 2024-3. Since this version is actively used in many Korean government projects, I kindly request support for eGovFrame 2024-3 in the plugin.

Hi,

I was using Copliot successfully earlier, having version 0.5. Recently, I found that the version is updated, so I tried updating the Copilot plugin in my Eclipse-based IDE, STM32Cube IDE. However, I could not update the plugin as it is giving me below dependency error. kinldy suggest how can I move forward.
