Is your feature request related to a problem? Please describe.

Hi Srinesh,

Thank you so much for creating the fantastic plugin. It has been incredibly helpful for debugging Java code in Neovim. I wanted to check if nvim-java also supports remote debugging, as it is another frequently used functionality. I tried running the command :lua require'dap.ext.vscode'.load_launchjs(nil, nil) to load the configurations from .vscode/launch.json. However, when I start the debugging process, I encounter the following error message:

Error executing vim.schedule lua callback: ...e/nvim/lazy/nvim-java-core/lua/java-core/utils/async.lua:41: u
stack traceback:
[C]: in function 'error'
...e/nvim/lazy/nvim-java-core/lua/java-core/utils/async.lua:41: in function 'callback'
...nvim-java-core/lua/java-core/ls/clients/jdtls-client.lua:72: in function 'handler'
....mount_nvimAJdFQy/usr/share/nvim/runtime/lua/vim/lsp.lua:1393: in function ''
vim/_editor.lua: in function <vim/_editor.lua: 0>

I would appreciate any guidance or suggestions you can provide to resolve this issue.

Thank you once again for your excellent work!

Best regards,
Xuanlei

   @s1n7ax To make this work we should modify the debug launch arguments. The request parameter should be eq to attach and requires two additional parameters:port and serverName.

   Should these additional parameters be saved like profile parameters (gui with nui), or should we keep it simple and get the input via vim.fn.input without saving to the file (Im not sure how often remote debugging is used) ?

   @atm1020 @rahul-saini Thank you very much for your support.
   @atm1020 For my use case, as my application runs on GCP and I need to debug it on my local machine, I have to remote connect to GCP each time. This functionality is frequently used, so it's better to use a file for configuration. You can find this functionality in Intellij Remote Debug. Similarly, VSCode offers a similar functionality that can be configured in the launch.json. An example launch.json file is provided below:

   {
     "version": "0.2.0",
     "configurations": [
       {
         "type": "java",
         "name": "Debug :my-server",
         "request": "attach",
         "hostName": "localhost",
         "port": 47757,
         "projectName": "my-server"
       },
       {
         "type": "java",
         "name": "Debug :my-server:test",
         "request": "attach",
         "hostName": "localhost",
         "port": 5005,
         "projectName": "my-server"
       }
     ]
   }

   This is probably something already solved by overseer.nvim. I remember an issue from the author to request some features related to this

   I would like to use this, we're running our application within a Docker container and I have enabled debugger within it and am able to connect to it using Intellij IDEA, but wanted to do the same with Neovim. All changes I have tried try to launch a debug session instead of just attaching to the one I already have.

   Actually I was able to get it to work with the launch.json, I just needed to set the correct 'projectName'
