Re: [m2e-dev] get archetype catalog failed(can't load Ahcwagon)-m2e-0.12.1 
Is the problem still present in m2e 1.0 SR1?

hi,
     I'm trying to use m2eclipse api to import projects by archetype.
my code is here:
RemoteCatalogFactory remoteCatalogFactory = new
RemoteCatalogFactory("http:/server1/archetype-catalog.xml", null, true);
ArchetypeCatalog catalog = remoteCatalogFactory.getArchetypeCatalog();
List<Archetype> archetypes = catalog.getArchetypes();
for (Archetype archetype : archetypes){
System.out.println(archetype.getArtifactId());
}

m2eclipse version is:0.12.1.
Got below exception:

*During debug, I found bundleloader is using org.maven.ide.eclipse's
bundle classloader to load AhcWagon class.*
*because maven embedder bundle haven't export AhcWagon's package, so
can't load it.*
*
*
*But my question is: caller(plexus-classworlds.jar) is in maven embedder
bundle and AhcWagon(in wagon-ahc.jar) is in the same bundle. Why not use
maven embedder's bundle loader to load AhcWagon?*

Am I something wrong to use this API?

That's great! If there is any sample code.

Regards
Simon
