Getting Started

Many parts of Oak are still under construction, so it may be a bit difficult to find your way around the codebase. The README files, this documentation, and the Oak mailing list archives are good places to start learning about Oak.

There is also the Jackrabbit 3 wiki page, which is mostly outdated though and should only be consulted for historical research.

To get started developing Oak, checkout the sources from svn, or fork them on GitHub. Then build the latest sources with Maven 3 and Java 7 (or higher) like this:

mvn clean install

To enable all integration tests, including the JCR TCK, use:

mvn clean install -PintegrationTesting

Before committing changes or submitting a patch, please make sure that the above integration testing build passes without errors. If you like, you can enable integration tests by default by setting the OAK_INTEGRATION_TESTING environment variable.

MongoDB integration

Parts of the Oak build expects a MongoDB instance to be available for testing. By default a MongoDB instance running on localhost is expected, and the relevant tests are simply skipped if such an instance is not found. You can also configure the build to use custom MongoDB settings with the following properties (shown with their default values):

-Dmongo.host=127.0.0.1
-Dmongo.port=27017
-Dmongo.db=MongoMKDB
-Dmongo.db2=MongoMKDB2

Note that the configured test databases will be dropped by the test cases.
