Doesn't recognize imports in classpath on a simple project

[mdacach]

coc-java doesn't seem to recognize my $CLASSPATH variable.
https://algs4.cs.princeton.edu/code/
I followed these instructions to set my classpath.
If I do :echo $CLASSPATH inside vim I get everything correctly, if I compile anything from the classpath it also works as expectedly. But coc-java does not offer completion regarding the classpath files and throws errors at every import from it.
This is a simple one file, not using anything.

Should be problem of your language server, checkout https://github.com/neoclide/coc.nvim/wiki/Debug-language-server#using-output-channel

I'm sorry could you help me some more. I didn't find anything wrong with the output.
Do you know how can I see what classpath the jdt.ls is using? or if I can change it with some command?

That's my relevant part in the code:
import edu.princeton.cs.algs4.WeightedQuickUnionUF;
That is the settings it shows (I tried adding the classpath to the vmargs):

And this is the error part:

It has a lot more lines but I don't think they are relevant, maybe this initial part here that has the errors too:

Any help would be greately appreciated. I don't know my way around this stuff and couldn't find relevant information neither at the eclipse jdt page, or the vscode-java or anything

Update: jdt will in fact not recognize your env classpath.
To use jars from libraries you need to update the java.project.referencedLibraries

@mdacach
I have similar issue.
I've set java.project.referencedLibraries in coc-settings.json .

But it still raises the unresolve error.

Did you have similar problems ever?

Thanks!

My problem is solved by configure the .classpath

Same issue here for me.
I've also tried configuring a .classpath file - no help.

My problem is solved by configure the .classpath

Where is this file you have changed?

I tried changing the .classpath files in ~/.config/coc/extensions/coc-java-data/*/*/.classpath, but after I change them and try using vim the changes are discarded and the files are the same as before.

I can't get the libraries of Princeton algs4 into working even after adding the path to the java.project.referencedLibraries

"java.project.referencedLibraries": [
  "/home/andre/.local/share/algs4/algs4.jar",
  "/home/andre/.local/share/algs4/lift/lib/algs4.jar",
  "/home/andre/.local/share/algs4/lift/lib/introcs.jar",
  "/home/andre/.local/share/algs4/lift/lib/stdlib.jar",
]

Did any of you were able to get it working?

UPDATE: After migrating from vim to neovim it worked very well! The issue is that coc-settings.json must be under ~/.config/nvim and it seems to only work with neovim.
