Hi guys,

I'm using Shrinkwrap on XWiki and it's great. However it's very slow ATM and I'm wondering why. Doesn't Shrinkwrap check if the artifact is in the local repo or in the CP before checking in the maven remote repos specified? Is it possible to have this behavior?

Here's how I use Shrinkwrap:

List<MavenResolvedArtifact> artifacts = resolveArtifactWithDependencies(

  String.format("org.xwiki.platform:xwiki-platform-distribution-war-dependencies:pom:%s", version));

protected List<MavenResolvedArtifact> resolveArtifactWithDependencies(String gav)

{

   return getConfigurableMavenResolverSystem()

       .resolve(gav)

       .withTransitivity()

       .asList(MavenResolvedArtifact.class);

}

protected ConfigurableMavenResolverSystem getConfigurableMavenResolverSystem()

{

   return Maven.configureResolver()

       .withClassPathResolution(true)

       .withRemoteRepo(

             "mavenXWikiSnapshot", "http://nexus.xwiki.org/nexus/content/groups/public-snapshots", "default")

       .withRemoteRepo(

             "mavenXWiki", "http://nexus.xwiki.org/nexus/content/groups/public", "default");

}

And in the logs I get tons of stuff like:
