Description

Maven by default generates a meta data directory under META-INF (META-INF/maven) containing the poms of bundled dependencies.

I have yet to see a use-case for these, and it can cause issues like FLINK-22555 where a part of the library was missed in the exclusions.

Let's just remove this directory.
