Tamas Cservenak commented on MPLUGIN-524:
-----------------------------------------
Just take a peek at stack trace:
*
{{org.sonatype.nexus.maven.staging.deploy.strategy.AbstractDeployStrategy.deployUp}}
initiates a deploy
* goes thru {{org.eclipse.aether.internal.impl.DefaultDeployer}}
* and then resolver ends up here, in a Maven2 class
[https://github.com/apache/maven/blob/master/maven-compat/src/main/java/org/apache/maven/artifact/repository/metadata/MetadataBridge.java]
* hence, it means that DeployRequest.metadata contained this Maven2 class, and
request was created by offender in first bullet
> "org.apache.maven.artifact.repository.metadata.Plugin.getPrefix() is null"
> with Nexus Staging plugin
