bug: DAP config not found - multimodule projects

[aarain1066]

Did you check docs and existing issues?

• I have read all the plugin docs
• I have searched the existing issues
• I have searched the existing issues of plugins related to this issue

Neovim version (nvim -v)

NVIM v0.9.5

Operating system/version

MacOS 14.4.1

Describe the bug

Very similar to this closed issue, however a colleague of mine and I are not able to run enable the debugger. I noticed this when I started opening a file in our java project (built w/ maven) and all things were functioning normally, however breakpoint would not be set when I hit space db. Then doing space dc said

"No configuration found for java. You need to add configs to dap.configurations.java (See :h dap-configuration)"

Two more interesting things to note

• when I open a java file is looks like it starts to configure DAP, and then immediately says it terminates it.
• when I run :JavaRunnerRunMain it returns Config not found

Previous resolution suggested to pull latest version, but installed freshly (using these steps) today (April 25 2024). As previous contributor suggested on the original issue, this issue still seems to exist for multimodule projects.

Steps To Reproduce

1.) Install following these instructions.

2.) Open a java file in a java project, specifically a test file.

3.) use hotkey space db to add a breakpoint (or manual command) and observe nothing happens.

Expected Behavior

to see breakpoint set on line where debug breakpoint hotkey was keyed in.

A previous workaround mentioned adding a new file to the root level. This ended up reloading the whole project, but after the reloading had completed there was a significant performance impact when using it normally to navigate a file and you were still not able to set a breakpoint.

@s1n7ax I run some tests using this repository and I believe issue is that, the project workspace directory is not unique (There is an open issue in nvim-java-core project releted to this).
I think unique workspace directory will solve project load issue, so the run/debug API should work as expected, but I'm not sure the breakpoint creation error is releated to this.

I used this branch during the tests. ( the AstroVim java pack use this way to generate unique worksapce folder)

This is fixed now: nvim-java/nvim-java-core#54

@s1n7ax same question.
If it is a multi-tiered project, only the bottom tier is recognized.
eg:

/
-- .git
-- pom.xml
-- modules
    -- pom.xml
    -- base
        -- src
            -- main
                -- java
                    -- com
                        -- xx
                            -- *.java
                            -- *.java
                            -- *.java
                -- resources
        -- pom.xml
    -- main
        -- src
            -- main
                -- java
                    -- com
                        -- xx
                            -- Application.java
                -- resources
        -- pom.xml

When I open nvim in the project root directory, the directory tree is normal.

When I open Application.java, the directory tree has changed, and now there is only the bottom module.

Maybe should check .git parent as root directory.
I try set

  opts = {
    root_markers = {
      ".git",
    },
  },

but no work.
