* A collection of artifacts for java compilations. It concisely describes the
* outputs of a java-related rule, with runtime jars, compile-time jars,
* unfiltered compile-time jars (these are run through ijar if they are
* dependent upon by another target), source ijars, and instrumentation
* manifests. Not all rules generate all kinds of artifacts. Each java-related
* rule should add both a runtime jar and either a compile-time jar or an
* unfiltered compile-time jar.
*
* <p>An instance of this class only collects the data for the current target,
* not for the transitive closure of targets, so these still need to be
* collected using some other mechanism, such as the {@link
