[ovirt-devel] CI broken - builds fail early in "loading code" stage with "attempted duplicate class definition for name: "Project""

Example builds: - http://jenkins.ovirt.org/job/vdsm_standard-check-patch/12526/ - http://jenkins.ovirt.org/job/vdsm_standard-check-patch/12527/ java.lang.LinkageError: loader (instance of
