Note the similarities of this parent POM to the parent POM defined in simple-parent Project POM. The only real difference between these two POMs is the list of submodules. Where that example only listed two submodules, this parent POM lists five submodules. The next few sections explore each of these five submodules in some detail. Because our example uses Java annotations, we’ve configured the compiler to target the Java 5 JVM.
