Description

ProjectBuildingRequest request = ...
ProjectBuilder builder = plexus.lookup(ProjectBuilder.class);
builder.build(file, request);

When the build method is called, the following exception is thrown:

java.lang.UnsupportedOperationException
	at java.util.AbstractMap.put(AbstractMap.java:209)
	at org.apache.maven.project.DefaultProjectBuilder.initProject(DefaultProjectBuilder.java:815)
	at org.apache.maven.project.DefaultProjectBuilder.build(DefaultProjectBuilder.java:174)
	at org.apache.maven.project.DefaultProjectBuilder.build(DefaultProjectBuilder.java:118)

The code should be reviewed. This is the offending code inside DefaultProjectBuilder:

                    Artifact artifact = repositorySystem.createDependencyArtifact( d );

                    if ( artifact == null )
                    {
                        map = Collections.emptyMap();
                    }

                    map.put( d.getManagementKey(), artifact );
