> It appears that the NAR maven plugin was benefiting from behavior in older version of the maven-dependency-tree library that would resolve artifacts in addition to poms when crawling dependendncies. This guaranteed that they would be in the local Maven repository/cache when in the Extension Documentation generation phase of NAR building.
> Version 1.4.0 of the plugin upgraded maven-dependency-tree to 3.2.0, which included this behavior change to only download poms:
> https://github.com/apache/maven-dependency-tree/commit/b330fa93b70e35c70a8afa75f0404cf47d5935d6
> This broke building NARs that are external from the Apache NiFi repository/project that inherit from (or depend on) NiFi NARs that have transitive dependencies marked as provided, because the Extension Documentation generation needs the full artifact resolved in order to create a working ClassLoader. Not having artifacts resolved results in error messages such as:

> Specifically, our code needs to be updated so that artifacts are resolved, using remote repositories if necessary, which they are not in the current plugin implementation.
