GitHub Copilot

I updated the Eclipse version, installed the plugin, authenticated on GitHub via the browser, and Eclipse is not updating the login.

If I try a second time, this error appears:

Sign in failed: org.eclipse.lsp4j.jsonrpc.ResponseErrorException: Could not log in with device flow on github.com: self-signed certificate in certificate chain

Do we have a solution?

Is auto-scroll down chat windows could be added, it's kinda annoying.
Yes I know it's only me been lazy.

Hi
When I install the plugin and run Eclipse 2025-03, I encounter the following error:
  "self-signed certificate in certificate chain."
Could this issue be related to using it within the company network?
If there is a guide to resolve this, I would like to receive it.

I have installed the GitHub Copilot plugin, configured with my organization enterprise endpoint.
I have been able to login and authorized the pluguin in my GitHub Copilot account.

But when I try to send a promt i allways recieve and HTTP 400 Message

Even after manual update of certificate getting error  

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

Hi,

We installed latest eclipse and was trying to install plugin and sign-in to github and got the  following error.

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

Any solution for this error?

Hi Team,

java.lang.IllegalStateException: Failed to start copilot language server.
  at com.microsoft.copilot.eclipse.ui.CopilotUi$1.run(CopilotUi.java:64)
  at org.eclipse.core.internal.jobs.Worker.run(Worker.java:63)

If I specify -Xverify:none in eclipse.ini, the above error occurs during startup and I cannot use Copilot. Is there any solution?

Hi Team,

Thank you for the plugin. When can we expect GA release of this plugin available.

Hallo Team,

Is there any update on:

Error Analysis

The error com.sap.adt.cds.ddl.ui.internal.editors.pages.DdlSourcePage$2 cannot be cast to org.eclipse.jface.text.ITextViewer indicates a plugin compatibility issue between GitHub Copilot and SAP’s ABAP Development Tools (ADT) in Eclipse.

Root Cause:

• SAP ADT uses custom editors (e.g., DdlSourcePage) that do not implement standard Eclipse text editor interfaces like ITextViewer.
• GitHub Copilot’s Eclipse plugin attempts to cast SAP’s editor instance to ITextViewer for code suggestions, which fails.

Currently Using Eclipse for ABAP Development.

Hi, on MacOS the installation through Eclipse is failing. 
 

It looks like it's depending on itself to be installed already, could you guys check how this could be resolved?

Cannot complete the install because one or more required items could not be found.
