Enhance project_root detecting. And auto cd to project_root, if not, when we invoke nvim from $HOME, i.e. cd $HOME && nvim dev/myproject/src/main/..../Test.java, jdtls will start all gradle instances in .gradle/wrapper/, it could be tens of java instances, that is definitely unexpected.
Move g:FILE_SEP to utils.vim as g:utils#FILE_SEP then we can load jc.nvim only with java files. I have tried to load jc with autocmd FileType java, jc.vim complains that g:FILE_SEP was not defined as it is initialized in project_root.vim, define it as util#FILE_SEP could solve it.

Make jdtls config.settings configurable. I need to add more JavaSE versions to jdtls. I can do it now in init.vim:

lua << EOF
require'jc'.setup{
settings = {
  java = {
    configuration = {
      runtimes = {
        {
          name = 'JavaSE-11',
          path = '/Library/Java/JavaVirtualMachines/java11/Contents/Home/'
        },
        {
          name = 'JavaSE-17',
          path = '/Library/Java/JavaVirtualMachines/java17/Contents/Home/'
        },
        {
          name = 'JavaSE-1.8',
          path = '/Library/Java/JavaVirtualMachines/java8/Contents/Home/',
          default = true
        }
      }
 }
}
}
EOF

Another small fix, config_linux is hard-coded in lua script. Now I introduce a new variable utils#OS in utils.vim.
