/**
 * This is a test set for <a href="https://issues.apache.org/jira/browse/MNG-2720">MNG-2720</a>.
 * 
 * This test will ensure that running the 'package' phase on a multimodule build with child
 * interdependency will result in one child using the JAR of the other child in its compile
 * classpath, NOT the target/classes directory. This is critical, since sibling projects might
 * use literally ANY artifact produced by another module project, and limiting to target/classes
 * and target/test-classes eliminates many of the options that would be possible if the dependent
 * sibling were built on its own.
