Root cause

Artifact org.itsallcode.openfasttrace:openfasttrace is a fat jar produced with maven-shade-plugin but still declares it's dependencies in pom.xml, because of setting <createDependencyReducedPom>false</createDependencyReducedPom>:

Proposed solution

• Change configuration of maven-shade-plugin:
  • Set createDependencyReducedPom to true to create a pom without dependencies
