Subject: Re: Plugin, how to resolve single dependency

If the idea is to resolve an artifact when you know
groupId:artifactId:version[:type:classifier]

Try

     @Component
     protected ArtifactResolver resolver;

    @Component
    protected ArtifactFactory artifactFactory;

    @Parameter(property = "localRepository", readonly = true)
    protected ArtifactRepository localRepository;

   @Parameter( defaultValue = "${project.remoteArtifactRepositories}",
readonly = true, required = true )
    protected List<ArtifactRepository> remoteRepositories;


    protected Artifact resolve( String groupId, String artifactId,
String version, String type, String classifier )
        throws MojoExecutionException
    {
        Artifact artifact =
artifactFactory.createArtifactWithClassifier( groupId, artifactId,
version, type, classifier );
        resolver.resolve(artifact, remoteRepositories, localRepository);
        return artifact;
    }
