The maven `dependency:go-offline` plugin has various issues
(see https://issues.apache.org/jira/browse/MDEP-204 and other
issues in that tracker), which the dedicated plugin from
https://github.com/qaware/go-offline-maven-plugin largely
fixes. I have confirmed that for an application I'm packaging
outside of nixpkgs, dependency-track, this indeed makes the
build work while it didn't with `dependency:go-offline`.
The offline mode is only used in one place in nixpkgs, for
lemminx. That build still succeeds and the program starts, though
I haven't tested further.
lemminx: add git properties file
Lemminx reads the version and git commit at runtime from a
git.properties file on the classpath. As a result, we need to create it.
lemminx: add comments to mvn flags
lemminx: add update script
lemminx: disable flaky tests
lemminx: move to pkgs/by-name
