fix: prefer sourcePaths before JDT source URIs - #629
Merged
Conversation
When JDT source lookup returns a non-file URI, check debug sourcePaths before returning that URI to the client. Add a regression test covering cached JDT URI results being overridden by sourcePaths. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Pull request overview
This PR updates stack trace source resolution so that when the debugger/JDT source lookup yields a non-file URI (e.g., jdt://...), the adapter will first attempt to resolve a real local source file via user-provided sourcePaths, while keeping the existing URI fallback when no local match exists.
Changes:
- Prefer resolving sources from
sourcePathsbefore returning non-file:URIs from the source lookup cache. - Refactor source resolution into small helper methods (
getSourceReference,resolveSourceFromSourcePaths). - Add a regression test ensuring a cached
jdt://source can be overridden bysourcePathswhen a matching local file exists.
