> 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{{session.getProjectDependencyGraph()}}, then the dependency graph is out of date.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}}.
