Can data directory be subdirectory of project directory?

[dave-kennedy]

I read in a few places that the data directory can't be the same as the project directory. But what about a subdirectory? In this case I'm trying to use root_dir/.workspace but getting that "Class.java is a non-project-file" error:

local root_dir = require('jdtls.setup').find_root({'.git', 'mvnw', 'gradlew'})

local config = {
    cmd = {
        'java',
        '-Declipse.application=org.eclipse.jdt.ls.core.id1',
        '-Dosgi.bundles.defaultStartLevel=4',
        '-Declipse.product=org.eclipse.jdt.ls.core.product',
        '-Dlog.level=ALL',
        '-noverify',
        '-Xmx1G',
        '--add-modules=ALL-SYSTEM',
        '--add-opens', 'java.base/java.util=ALL-UNNAMED',
        '--add-opens', 'java.base/java.lang=ALL-UNNAMED',
        '-jar', '/home/dave/.jdtls/plugins/org.eclipse.equinox.launcher_1.6.400.v20210924-0641.jar',
        '-configuration', '/home/dave/.jdtls/config_linux',
        '-data', root_dir .. '/.workspace'
    },
    root_dir = root_dir,
    settings = {
        java = {
            configuration = {
                runtimes = {
                    {
                        name = 'JavaSE-1.8',
                        path = '/home/dave/.sdkman/candidates/java/8.0.302-open/',
                    }
                }
            }
        }
    }
}

That doesn't work. I'm not sure why exactly that restriction is in place. Would be something to ask in eclipse.jdt.ls, it's not related to the client

[dave-kennedy]

Honestly it took so much effort to get this working, and then it wasn't picking up my libs, I finally gave up. IntelliJ + IdeaVim is so much easier.

Yeah I saw that. Funny thing is I just started up IntelliJ and watched my CPU usage spike to 95%. I really wish there was an easy, modern solution for Vim.
