  • code completion
  • signature help
  • hover info
  • code actions
  • formatting
  • find references

Troubleshoot

Server exits with code 13

The server caches workspace specific information. When this data is corrupted the server crashes with exit code 13 and the server is disabled for the current project.

Run the command LSP-jdtls: Clear data from the command palette and re-enable the server using the command LSP: Enable Language Server in Project.
