[m2e-dev] get archetype catalog failed(can't load Ahcwagon)-m2e-0.12.1

[Wang YunFeng <wangyf2010@xxxxxxxxx>]

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:

1) Error injecting: org.sonatype.maven.wagon.AhcWagon

  at ClassRealm[plexus.core, parent: null]

  while locating org.apache.maven.wagon.Wagon annotated with @com.google.inject.name.Named(value=http)

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
