Konrad Windszus commented on MNG-6965:
--------------------------------------
Although plexus-utils is mostly part of the Core Classloader
(https://github.com/apache/maven/blob/9b656c72d54e5bacbed989b64718c159fe39b537/maven-core/src/main/resources/META-INF/maven/extension.xml#L79-L83)
and therefore should only be referenced with "provided" scope according to
https://issues.apache.org/jira/browse/MNG-7097, the
https://github.com/apache/maven/blob/maven-3.8.4/maven-core/src/main/java/org/apache/maven/plugin/internal/PlexusUtilsInjector.java
does not consider "provided" dependencies, and therefore references
plexus-utils 1.1 whenever the plexus-utils in some newer version is referenced
with "provided" scope.
As this seems pretty severe, I would strongly recommend backporting this to 3.9.

> 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.
