GrEclipseFormatterStep fails when ~/.m2/ is not writable #1797
Description
In our CI environment, the build user cannot write to their own home directory, but we configure ~/.m2/settings.xml to change the local repository a separate mount for builds:
<localRepository>/agent/.m2/repository</localRepository>
However the configuration of P2Model here doesn't reflect that setting, and tries to write to the read-only location:
