Description

A simple minimal archetype pom following the manual pages downloads plexus-utils 1.1, even though it is not (apparently) declared anywhere. This version is banned at my organization (edited to add: due to vulnerabilities), meaning such a pom always fails.

Running any goal, such as mvn -X clean, produces the following before the goal is executed:

[DEBUG] Dependency collection stats: {ConflictMarker.analyzeTime=952800, ConflictMarker.markTime=586900, ConflictMarker.nodeCount=1, ConflictIdSorter.graphTime=549200, ConflictIdSorter.topsortTime=586700, ConflictIdSorter.conflictIdCount=1, ConflictIdSorter.conflictIdCycleCount=0, ConflictResolver.totalTime=3313100, ConflictResolver.conflictItemCount=1, DefaultDependencyCollector.collectTime=66890900, DefaultDependencyCollector.transformTime=8523500}
[DEBUG] org.apache.maven.archetype:archetype-packaging:jar:3.1.2:
[DEBUG]    org.codehaus.plexus:plexus-utils:jar:1.1:runtime

 

As far as I can see, there is no declared dependency on plexus-utils:1.1.
