Problems with jdt:// links from nvim-jdtls

[mikehaertl]

Describe the bug

The new version 0.3 seems to bring back many problems with jdt://... links. For example when opening the finder on a method that is only available from a jar package I get this error:

Error executing vim.schedule lua callback: BufReadCmd Autokommandos für "jdt://*": Vim(lua):Error executing vim.schedule lua callback: .../mike/.local/share/nvim/plugged/nvim-jdtls/lua/jdtls.lua:1187: Vim:Error

Steps to reproduce

What does not work, when on a method from an imported library method:

• Lspsaga peek_definition (but lua vim.lsp.buf.definition() works!)
• Lspsaga finder

As usual the Java setup is not so easy, so I can not provide a simple procedure to reproduce.

I can help debugging it, though (i.e. provide LSP debug logs or add debug output if desired).

Expected behavior

It worked fine before the new 0.3.

:lua vim.lsp.buf.implemenation() works for me, no error. Same with :lua vim.lsp.buf.definition(): no error.

finder also work

[glepnir]

but some bug need fix .

[mikehaertl]

Hmm, I first see the above error. When I enter <CR> the finder opens.

[mikehaertl]

Ok, the error is only when I first open the finder. The preview does not work then.

When I close and open the finder again, it seems to work.

[glepnir]

yep I reproduce this and fixing now.

[glepnir]

could you try it now ?

[mikehaertl]

I did a quick test and it looks good! No errors so far.

Thank you!

[glepnir]

Thanks for your patience in teaching me how to reproduce the problem

[mikehaertl]

No problem - but please keep your Java setup. Just to make sure ... 😄
