Konrad Windszus commented on MPLUGIN-385:
-----------------------------------------
A quick search on Maven central exposes 56 artifacts with group id
"org.apache.maven" (https://search.maven.org/search?q=g:org.apache.maven), but
the core extensions only lists 24 of them
(https://github.com/apache/maven/blob/master/maven-core/src/main/resources/META-INF/maven/extension.xml#L133-L193).
Also artifacts with other group ids are part of the core classpath (shouldn't
those have "provided" scope as well?)
> Clarify usage of scope "provided" for Maven artifacts with group id
> "org.apache.maven"

> Key: MPLUGIN-385
> URL: https://issues.apache.org/jira/browse/MPLUGIN-385
> Project: Maven Plugin Tools
> Issue Type: Improvement
> Components: Plugin Plugin
> Affects Versions: 3.6.2
> Reporter: Konrad Windszus
> Priority: Major
>
> Since m-plugin-p 3.6.2 (MPLUGIN-370) all dependencies with group id
> {{org.apache.maven}} are supposed to be referenced with scope {{provided}}.
> But once turning dependency {{org.apache.maven:maven-archiver:3.5.1}} to
> scope provided my ITs based on
> {{org.apache.maven.shared:maven-verifier:1.7.2}} are starting to fail with
> NCDF errors
> {code}
> java.lang.NoClassDefFoundError:
> Lorg/apache/maven/archiver/MavenArchiveConfiguration;
> {code}
> Is that a bug in the classloader with maven-verifier? What if I want to use a
> newer version than shipped with Maven like "maven-archiver 3.5.1"?
> What about group ids starting with "org.apache.maven" like
> "org.apache.maven.shared"?
> You can reproduce with
> https://github.com/apache/jackrabbit-filevault-package-maven-plugin.
