Why submodules?

In Git you can add a submodule to a repository. This is basically a repository embedded in your main repository. This can be very useful. A couple of usecases of submodules:

• Separate big codebases into multiple repositories.

// Name of the matrix job to configure
def jobName = 'MATRIX'

// Get the matrix job
def job = hudson.model.Hudson.instance.getItem(jobName)
assert job != null, "The job $jobName could not be found"

// Check it is a matrix job
assert job.getClass() == hudson.matrix.MatrixProject.class, "The job $jobName is of class '${job.getClass().name}', but expecting 'hudson.matrix.MatrixProject'"
