+### Fail build that tries to produce an unwanted artifact
+
+_Requirement:_ If an artifact output is not specified for the project,
+fail a build that tries to make one.
+
+_Justification:_ If a build tries to create an artifact, but one isn't
+wanted, the build should fail.
+
+_Stakeholder:_ Lars.
