jdtls fails to start after clearing ~/.m2/repository #429

Open udalrich opened 1 year ago

udalrich commented 1 year ago

Describe the bug

After deleting my ~/.m2/repository, jdtls no longer starts. It is looking for a jar in my m2 which no longer exists. The jar is not used in the project that I am working on, but was used in one that I used in the past.

Note This is a caching issue, so a clean config will not have the problem.

To Reproduce Create a maven project that uses org/projectlombok/lombok/1.18.22/lombok-1.18.22 Edit a Java file in that project. Create a maven project that does not use that version of Lombok. Edit a Java file in that project. Delete ~/.m2/repository In the second project, run mvn install so that all dependencies for that project are downloaded. Open emacs and edit a file in the second project. Start lsp-java if not set up to do that automatically. Select i or . when asked to import the project.

You will get a message that jdtls exited, asking if you want to restart it. Restarting will give you the same error message. The jdtls::stderr buffer will contain many instances of 

Process jdtls stderr finished
Error opening zip file or JAR manifest missing : /Users/me/.m2/repository/org/projectlombok/lombok/1.18.22/lombok-1.18.22.jar

Expected behavior jdtls starts without errors and lsp-java works.

Maybe you cloud use lsp-workspace-folders-remove and remove the project which is no needful. And use lsp-workspace-restart for restart your jdtls.
