While the team reviews your request, I wanted to provide some possible tips and documentation that might help you in the meantime.
Suggestions to troubleshoot and work around the missing quick actions:
- Verify editor and Java code‐action settings:
- "editor.lightbulb.enabled": true
- "java.errors.showInProblemsView": true
- Confirm the Java Language Server is running without errors:
- View → Output → select “Java Language Server” → look for startup errors
- Trigger the import/code‐action via keyboard (e.g. Ctrl+. / ⌥⏎) while the editor cursor is on the error
- Update VS Code and the Java extensions to the latest versions (1.27.0 → 1.x)
