          <description>The default goal (or phase in Maven 2) to execute when none is specified for
            the project. Note that in case of a multi-module build, only the default goal of the top-level
            project is relevant, i.e. the default goals of child modules are ignored. Since Maven 3,
            multiple goals/phases can be separated by whitespace.</description>

The most important stubs are:
LifecycleExecutionPlanCalculatorStub
ProjectDependencyGraphStub

Since they define the primary structure of the project/build.

The stubs define three top-level targets that are defined in  LifecycleTaskSegmentCalculatorStub;
clean, aggr and install. "aggr" is an aggregating task while clean and install are lifecyclephases.
There will be three items in the task list for this dataset.
