I am having two little problem with the Aether-API. I am trying to download/resolve the latest version of some artifacts.
According to the examples ( http://git.eclipse.org/c/aether/aether-demo.git/tree/aether-demo-snippets/src/main/java/org/eclipse/aether/examples/FindNewestVersion.java ) it is possible to get the latest version when using [0,) as version-coordinate. I am following the example but when using this snippet I get a ArtifactNotFoundException. When I use the actual version (1.3.0-SNAPSHOT) the VersionRange gets resolved.
Just in case I missed somethinig, here is my code (using Guice for setup). I add my local maven-repository as a remote because I want to test with some artifacts that are not yet in our projects nexus. But this shouldnt matter at all and it doesnt change anything when I remove it.
public class GuiceRepositorySystemFactory
{
public static RepositorySystem newRepositorySystem()
{
return Guice.createInjector(new AetherModule()).getInstance(RepositorySystem.class);
}
}

public class AetherModule extends AbstractModule

bind(TransporterFactory.class).annotatedWith(Names.named("file")).to(FileTransporterFactory.class);
bind(TransporterFactory.class).annotatedWith(Names.named("http")).to(HttpTransporterFactory.class);
}
