There should be no SNAPSHOT dependencies in any CI build. While it does build core beforehand, it might get overwritten by another CI run.
[org.wildfly.core:wildfly-core-parent] [INFO] Installing /opt/buildAgent/work/db872761b443af46/core/pom.xml to /store/repository/org/wildfly/core/wildfly-core-parent/2.0.8.Final-SNAPSHOT/wildfly-core-parent-2.0.8.Final-SNAPSHOT.pom
Would it be possible to use timed snapshots instead?
