[doom emacs] lsp-java error "The declared package does'not match the Expected package "".

Restarted emacs multiple times , the error is shownig every time , even though the project directory is correct.

Most likely wrong root selection. Use m-x lsp-worskspace-folders-add/remove

Now , it is showing , .java is a non-project file , only syntax errors are reported.

That is indication for bad project root
