Description

Environment

  • OS: Windows
  • Eclipse Version: 2026-03
  • Plugin Version: 0.18.0

Describe the bug
When a project backed by a non-file:// URI scheme (e.g. an RSE remote project
mounted over SSH) is present in the Eclipse workspace, sending a message in the
Copilot Chat view fails and an error is returned instead of a response.

To Reproduce
Steps to reproduce the behavior:

  1. Add a remote project to the workspace via RSE (or any other non-file:// provider).
  2. Open the Copilot Chat view.
  3. Send any message.

Expected behavior
Chat responds normally, ignoring or gracefully skipping workspace folders whose
URI scheme is not file://.

Research direction

Start in the Copilot Chat view and trace how workspace folders are handled when a message is sent. Reproduce with an RSE project or another non-file:// provider in an Eclipse workspace, then verify that those folders are skipped or handled gracefully and that the chat returns a response.
