I don’t see gradle integration coming. When we’d finished it, Google would probably switch to something else :P
But you should be able to use a Generic Project for that: File > New > Import Project > Import Existing Project. (For the language server you should probably import the module base directory?)
That could probably be made more obvious… like not putting it at the end of a category with lots of version control related items, and calling it something like Import Directory or such (there doesn’t need to be a “project” of any kind).

The java-language-server would/should solve the “parse and edit” part.
I have not tried it, but probably setting it up as “Start Server per Project” is required, and probably having the module path as the base of the Qt Creator project.
Also, Qt Creator still has a specialized Java editor from the pre-LSP times, which might interfere with the language client, so switching the handler for text/x-java to “Plain Text Editor” in Preferences > Environment > MIME Types might be needed to.

I agree that someone should check this, potentially throwing the old Java editor away, and maybe Qt Creator can help a bit with setting up the Java language server too, similar to what we do for Python.
