Stop generating .project .classpath .settings/ files

[ghost]

This issue has already been solved in vscode-java in redhat-developer/vscode-java#2153
and Eclipse JDT Language Server (eclipse.jdt.ls) in eclipse-jdtls/eclipse.jdt.ls#1900 and there
is even a blog post about it at https://devblogs.microsoft.com/java/say-goodbye-to-project-files-in-1-1-0

coc-java running on Vim (8.2) and Node.js (16.14.0) on Fedora Linux (35) still generates those files.

I was able to get things working by adding "java.jdt.ls.vmargs": "-Djava.import.generatesMetadataFilesAtProjectRoot=false" to my :CocConfig file. I'm not sure why this isn't the default from coc-java, but I haven't looked very hard into how it launches the language server.

@chemzqm any insight on this?

Need some time to upgrade coc-java, I used to have issues with java environment on my machine and some components are missing from coc.nvim.

Should be fixed on recent version of coc-java, try upgrade coc.nvim to latest release and coc-java to version 1.14.0.
