Not really - it's more of an intermediate step to aid initial Maven2 adoption for an existing build system. Over time we'll hopefully be able to consume pom.xml directly. We'll be sure to file any necessary enhancements or bugs that would otherwise prevent our migration to the standard pom.xmlsyntax. > > For example, could one provide a CustomMavenProjectBuilder and then > > register it as a Plexus MavenProjectBuilder component? > > Yes. > > > How would Maven2 decide which implementation to use, if both the > > Default and Custom implementations were registered on the M2 > > classpath? > > Plexus allows multiple implementations of a component which you select > by a component id or role hint as we call it in Plexus.

Agreed 100%. To get this working, we'd register a custom implementation with the same <role>, but a different <role-hint>, say <role-hint>custom-syntax</role-hint>? Then we would have to directly update META-INF/plexus/components.xml to add that <role-hint> to the <requirements> section of whatever consumes the MavenProjectBuilder <role>, right? Does that mean we'd need to update the following from maven-core-2.0.jar!/META-INF/plexus/components.xml? <component> <role>org.apache.maven.Maven</role> <implementation>org.apache.maven.DefaultMaven</implementation> <requirements> <requirement> <role>org.apache.maven.project.MavenProjectBuilder</role> <role-hint>custom-syntax</role-hint> </requirement> <requirement> <role>org.apache.maven.lifecycle.LifecycleExecutor</role> </requirement> <requirement> <role>org.apache.maven.usability.diagnostics.ErrorDiagnostics</role> </requirement> <requirement> <role>org.apache.maven.execution.RuntimeInformation</role> </requirement> </requirements> </component> I was wondering if it was possible to put this in a different JAR, and leave maven-core-2.0.jar unchanged. This seems to imply that the <role> org.apache.maven.Maven</role> would need it's own <role-hint> as well. Is there a convenient way to get Maven2 to use a custom <role-hint> when discovering the <role>org.apache.maven.Maven</role> during "mvn" invocation?
