Change plexus-utils to compile scope from provided (#65)
Change plexus-utils to compile scope from provided (#65)

This is remnant from Maven2 and worked in Maven3 due
Maven3 backward compatibility layer toward Maven2. This is
getting removed in Maven 3.9.0 and 4.

Plexus Utils is now a compile scope dependency of the plugin,
because we can't expect Maven3 and 4 to provide it.

This fixes #64
