4 years ago Unable to start lsp means that I cannot run any lsp command, neither autocomplete or other features works.
The project uses OpenJDK 8

4 years ago Hm, I haven't tested with JDK 13 - it may need special adjustments - is this a requirement for you? Did you try to delete the workspace as well?

Did you try to delete the workspace as well?
I tried and then noticed there're no workspace cache in the directory. (there only exists 2 empty directories)
~/.emacs.d/.local/etc/java-workspace
jdt.ls-java-project/
bin/
src/lsp-java-workspace-dir is /Users/sei40kr/.emacs.d/.local/etc/java-workspace.
lsp-java-workspace-cache-dir is /Users/sei40kr/.emacs.d/.local/etc/java-workspace/.cache/.

4 years ago Also I tried OpenJDK11 and OpenJDK12 (installed with Homebrew) and it didn't work with them too.

4 years ago Can you provide the client-server logs? Also, what kind of project do you test with? Does it work fine with hello world application like this: https://github.com/emacs-lsp/dap-mode/tree/master/features/fixtures/test-project (if you clone the repo, make sure you pick the proper root in the import project dialog).

Sorry I don't know how to change the logging verbosity.
I didn't get anything on jdtls buffer with default verbosity.
I tested the hello world project above and it worked fine.
The project is https://github.com/VaughnVernon/IDDD_Samples. It uses Gradle.

4 years ago @sei40kr I checked the content of *lsp-log* and there is the following:

Sorry, I haven't seen lsp-log and there was a same error as you.
And it seems the gradlew in the project uses Gradle 2.3.
I removed it and retried, then I got another error:

4 years ago @sei40kr I have limited understanding about server internals - so if you get an error like that the best place to ask is in the JDT LS repo.
I have a legacy project that I need to work on, the folder structure of the project is like the following:
If I open the project on the root of it, I was unable to even start
lsp. If I openbusinessas my root folder, I can initializelspcorrectly, but the code completion wont work.Can anybody help me?
