I tried to follow the tutorial on this link and when I arrived to the Working with Java Project section, I found I cannot initialize a project. Everything shows up as expected until It asks for a project directory. After this, nothing happens even when JAVA_HOME and lsp-java-java-path are set manually.
Versions:
- emacs: 27.1
- lsp-java: 3.1
- dap-mode: 0.8
- lsp-mode: 9.0.0
- lsp-treemacs: 0.5
- treemacs: 3.1

;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.
