There are two folders named differently in the sources.zip compared to the pattern of other names.

It is:
org.uberfire-uberfire-parent-7.30.0.Final
org.kie.rhba-rhba-maven-repo-root-7.6.0-CR1-CR1

and it should be probably:
org.uberfire-uberfire-parent-7.30.0.Final-7.6.0-CR1
org.kie.rhba-rhba-maven-repo-root-7.6.0-CR1

This causes tests to fail
