Description Fred Bricon CLA 2011-09-05 08:13:25 EDT 
Build Identifier: 

Bugs #355292 and #349986 affecting mavenarchiver and m2e-wtp plugins are caused by plugin configurations using project.parent.* properties.

As a matter of fact, calling mavenProject.getParent() in AbstractBuildParticipant.build() causes this exception :

java.lang.IllegalStateException: no context maven session
	at org.eclipse.m2e.core.internal.embedder.ContextRepositorySystemSessionImpl.getSession(ContextRepositorySystemSessionImpl.java:48)
	at org.eclipse.m2e.core.internal.embedder.ContextRepositorySystemSessionImpl.getMirrorSelector(ContextRepositorySystemSessionImpl.java:102)
	at org.sonatype.aether.impl.internal.DefaultRemoteRepositoryManager.aggregateRepositories(DefaultRemoteRepositoryManager.java:139)
	at org.apache.maven.project.ProjectModelResolver.addRepository(ProjectModelResolver.java:119)
	at org.apache.maven.model.building.DefaultModelBuilder.configureResolver(DefaultModelBuilder.java:567)
	at org.apache.maven.model.building.DefaultModelBuilder.build(DefaultModelBuilder.java:306)
	at org.apache.maven.model.building.DefaultModelBuilder.build(DefaultModelBuilder.java:232)
	at org.apache.maven.project.DefaultProjectBuilder.build(DefaultProjectBuilder.java:135)
	at org.apache.maven.project.DefaultProjectBuilder.build(DefaultProjectBuilder.java:98)
	at org.apache.maven.project.MavenProject.getParent(MavenProject.java:359)

As a workaround, the parent projects can be manually loaded in each BuildParticipant implementations, but a proper solution would be to attach (and later detach) each project being built to the current maven session.

The same goes for projects being configured by project configurators.

 	

Reproducible: Always

@fred can you check if latest 1.4 is still affected? This issue may have been addressed as a side effect of introduction of IMavenExecutionContext.
