Changes were made to the plugin parent pom in v2.13 that cause the Blue Ocean build to fail.

Basically, the maven-surefire-plugin plugin must be configured with <argLine>-Djava.awt.headless=true</argLine>. If not, the jacoco-maven-plugin causes the build to fail with a complexity rule error.

Yeah ... that sounds totally weird, but it is the case. It must be a side effect of some other issue.

Worked around by adding an explicit config of maven-surefire-plugin to the root pom in blue ocean. That will prob need to be reviewed as part of resolving this ticket.
