We use maven to build the project. Some helpful maven commands:

mvn eclipse:eclipse Create the eclipse projects
mvn install Builds everything, runs unit & integration tests, installs into your maven repo
mvn install -Dmaven.test.skip=true As above, but without running tests
mvn test Runs unit tests
mvn verify Runs integration tests

The integration tests run against an OpenStack installation.
It takes its configuration from the system properties.

Useful properties:

The defaults should work with a local devstack installation. Otherwise do something like this:

mvn verify -Dopenstack.auth.url=http://192.168.71.1:5000/v2.0
