-----------------------------------
Assignee: Guillaume Nodet (was: Michael Osipov)
> Superfluous relocation warning messages
> ----------------------------------------
>
> Key: MNG-7349
> URL: https://issues.apache.org/jira/browse/MNG-7349
> Project: Maven
> Issue Type: Bug
> Components: Core
> Affects Versions: 3.8.3, 3.8.4
> Reporter: Joep Weijers
> Assignee: Guillaume Nodet
> Priority: Minor
> Fix For: waiting-for-feedback
>
>
> In the
> [commit|https://github.com/apache/maven/commit/a1ba33069fad1fb9c6e9cd458ad233ff3a74aadd]
> that solved MNG-7253, the check for relocations was moved from the
> DefaultProjectDependenciesResolver to the DefaultArtifactDescriptorReader.
> This means that the relocation messages are not only shown on project
> dependencies, but on any artifact that is read.
> This may lead to unfixable WARNINGS in the output if a plugin transitively
> uses a relocated artifact.
> This can be reproduced by calling {{mvn dependency:tree}} with a simple,
> empty {{{}pom.xml{}}}. This will give the following warning:
> {code:java}
> [WARNING] The artifact xml-apis:xml-apis:jar:2.0.2 has been relocated to
> xml-apis:xml-apis:jar:1.0.b2
> {code}
> The default maven-dependency-plugin version is 2.8 and it depends on
> {{{}org.apache.maven.reporting:maven-reporting-impl:2.0.5{}}}, which depends
> on {{commons-validator:commons-validator:1.2.0}} which depends on
> {{{}xml-apis:xml-apis:2.0.2{}}}.
> In this particular case, updating to a recent maven-dependency-plugin version
> solves the issue. But since the transitive dependencies of plugins are not
> under the control of the end users, I don't think this warning should be
> shown.
> *Workaround:*
> Stay on Maven 3.8.2 or disable logging on the DefaultArtifactDescriptorReader:
> {code:java}
> -Dorg.slf4j.simpleLogger.log.org.apache.maven.repository.internal.DefaultArtifactDescriptorReader=error
> {code}
> Although this disables all relocation messages, including the ones you might
> be interested in.
