How to disable java supporting?

[marryton007]

In my environment, I don't need java support, and it modifies my project files.

 ❯ git status tools 
On branch develop
Your branch is up to date with 'origin/develop'.

Changes not staged for commit:

        modified:   tools/tradefederation/core/remote/.project

the file content is modified like below:

So, How can I totally disable java support?

[marryton007]

I have modified 'plugin/coc.vim'

_ " coc.nvim 插件    
  " \ 'coc-css',    
  " \ 'coc-html',    
  " \ 'coc-java',    
  " \ 'coc-lua',    
  " \ 'coc-xml'    
  let s:coc_extensions = [    
        \ 'coc-pyright',    
        \ 'coc-explorer',       
        \ 'coc-word',    
        \ 'coc-cmake',    
        \ 'coc-dictionary',    
        \ 'coc-rust-analyzer',    
        \ 'coc-vimlsp',    
        \ 'coc-ci',    
        \ 'coc-snippets',    
        \ 'coc-vimtex',    
        \ 'coc-smartf',    
        \ 'coc-go',    
        \ 'coc-sh',    
        \ 'coc-git',    
        \ 'coc-diagnostic'    
        \]  

I also ran the commands

:CocUninstall  coc-lua coc-java coc-xml coc-jedi
:CocRebuild
:CocRestart

But it useless.

I'm not a Java expert and I'll try my best to solve your problem.

Firstly:

1. I think the modifications are caused by Java language server: https://github.com/eclipse/eclipse.jdt.ls
2. your modifications and commands to get rid of coc-java is correct, as far as I know.

There are my immature assumptions may helpful for your problem:

1. maybe it's not neovim's problem, have you ever opened the project with vscode
2. now that these files are caused by Java language server and you need the lsp, maybe just uninsall the lsp
3. make the modified files readonly temporally to find out which program caused the problem

[marryton007]

I tried two methods:

1. according to the coc-java quick start, remove directory "~/.config/coc/extensions/coc-java-data.
2. add "java.enabled: false" in coc config file.

It seems the problem is going away. but I don't know which one is right.
