For Aries, I ended up doing:
@Component
private org.apache.maven.repository.RepositorySystem repository;
private File resolve(String artifactDescriptor) {
String[] s = artifactDescriptor.split(":");
String type = (s.length >= 4 ? s[3] : "jar");
Artifact artifact = repository.createArtifact(s[0], s[1], s[2], type);
ArtifactResolutionRequest request = new ArtifactResolutionRequest();
request.setArtifact(artifact);
request.setResolveRoot(true).setResolveTransitively(false);
request.setServers( session.getRequest().getServers() );
request.setMirrors( session.getRequest().getMirrors() );
request.setProxies( session.getRequest().getProxies() );
request.setLocalRepository(session.getLocalRepository());
request.setRemoteRepositories(session.getRequest().getRemoteRepositories());
repository.resolve(request);
return artifact.getFile();
}
If you set “setResolveTransitively(true)” then the ArtifactResolutionResponse
would have all the deps available in it.
That seems to work for both Maven 3.0 and 3.1/3.2.
