Scope 'system' is unknown

[jflecomte]

Getting following stack trace when a transitive dependency has scope system:

[ERROR] Failed to execute goal org.basepom.maven:dependency-versions-check-maven-plugin:3.2.0:check (dependency-versions-check) on project MyArtifactId: Scope 'system' is unknown! -> [Help 1]

Can be reproduced using java 8 with following pom.xml file (java 8 is required only because the dependency is within a profile activated by java 8):

Hi,

Thank you for filing a bug report! Sorry this somehow slipped through the cracks. I will give it a look.
