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.

// leads to java.lang.NoClassDefFoundError: Lorg/apache/maven/graph/GraphBuilder;
@Requirement( hint = GraphBuilder.HINT )
private GraphBuilder graphBuilder;

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adds dependencies and another build extension uses session.getProjectDependencyGraph(), then the dependency graph is out of date.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.
