Re: [m2e-dev] Breaking changes to the archetype API -> m2e 2.0?

[Greg Amerson <gregory.amerson@xxxxxxxxxxx>]

Hey Fred,

Just want to clarify some of the APIs that may be changing.  In our adopter product we have code that looks like this:

final ArchetypeManager archetypeManager = MavenPluginActivator.getDefault().getArchetypeManager();

final ArtifactRepository remoteArchetypeRepository = archetypeManager.getArchetypeRepository( archetype );

...

final List<IProject> newProjects =

            projectConfigurationManager.createArchetypeProjects(

                location, archetype, groupId, artifactId, version, javaPackage, properties, configuration, monitor );

I'm assuming you mean some of these APIs will change in incompatible ways in the proposed m2e 2.0?  Well I guess ArchetypeManager was always marked internal, so its fair game to be changed even if m2e doesn't go to 2.0. But the IProjectConfigurationManager was "API", so is that one of the interfaces that will undergo breaking change in 2.0?

Is there any downside at all to upgrading? If you've done the work and fixed all those issues I'm super happy you've moved us forward.

Honestly I doubt anyone has tied into the guts of Archetype aside from you and really I think it's a small price to pay if the odd party is. You've updated the code and I assume made it easier to deal with so I only see upside.
