@Loggable(value=2,

          trim=false)
public final class Classpath
extends AbstractSet<File>
implements Set<File>

A classpath of a Maven Project.

It is a convenient wrapper around Aether class, that allows you to fetch all dependencies of a Maven Project by their scope. The class implements a Set of Files and can be used like this:

 String classpath = StringUtils.join(
   new Classpath(project, localRepo, "runtime")
   System.getProperty("path.separator")
 );

Important to notice that this class resolves artifacts from repositories only once per instance. It means that once resolved the list of files is cached and never flushes. In order to resolve again (if you think that content of repositories is changed), make a new instance of the class.
