Aether adapter for Maven plugins

More details are here: aether.jcabi.com

Aether is a dependency management toolkit for Maven repositories. It is very convenient to use Aether in your Maven plugins, when it's necessary to find a location of certain artifact or find out what transitive dependencies it contains. This module contains Aether class, an adapter between your plugin and Aether.

This is how you find out the location of a junit:junit-dep:4.10 artifact:

import com.jcabi.aether.Aether;
import java.io.File;
import org.apache.maven.plugin.AbstractMojo;
import org.sonatype.aether.RepositorySystemSession;
import org.sonatype.aether.artifact.Artifact;
import org.sonatype.aether.util.artifact.DefaultArtifact;
import org.sonatype.aether.util.artifact.JavaScopes;

public class MyMojo extends AbstractMojo {
  /**
   * @parameter default-value="${repositorySystemSession}"
   * @readonly
   */
  private RepositorySystemSession session;
  @Override
  public void execute() {
    File repo = this.session.getLocalRepository().getBasedir();
    Collection<Artifact> deps = new Aether(this.getProject(), repo).resolve(
      new DefaultArtifact("junit", "junit-dep", "", "jar", "4.10"),
      JavaScopes.COMPILE
    );
    // Now you have a full set of artifacts that include junit-dep.jar
    // and all its dependencies in "runtime" scope. The first
    // element in the collection is junit-dep.jar itself. You can use
    // Artifact#getFile() method to get its absolute path
  }
}
