<!-- START SNIPPET: ant-bootstrap

By default the bootstrap will use ~/.m2/repository as the integration repository but you can define the integration
repository by specifying a property on the command line:

ant -Dmaven.repo.local=/my/integration/repository

Those familiar with Maven will note this is the same way the local repository can be set from the command-line.
This facilitates having a set of builds converge on the same repository for integration purposes.

END SNIPPET: ant-bootstrap -->
