> Maven doesn't export org.apache.maven.graph
> -------------------------------------------

> Key: MNG-6972
> URL: https://issues.apache.org/jira/browse/MNG-6972
> Project: Maven
> Issue Type: Bug

> Affects Versions: 3.6.3

> Hi
> maven doesn't export org.apache.maven.graph package in
> maven-core/src/main/resources/META-INF/maven/extension.xml so the
> GraphBuilder is not usable in extensions.
> {code:java}
> // leads to java.lang.NoClassDefFoundError:
> Lorg/apache/maven/graph/GraphBuilder;
> @Requirement( hint = GraphBuilder.HINT )
> private GraphBuilder graphBuilder;
> {code}
> Background: if one build extension adds dependencies and another build
> extension uses {{session.getProjectDependencyGraph()}}, then the dependency
> graph is out of date. This is because the graph is only rebuilt after
> executing _all_ extensions. One solution to this would be to update the
> {{MavenSession}} and setting the new dependency graph in the first extension,
> but for this we need access to the {{GraphBuilder}}.
