Building Jackrabbit

The easiest way to use Jackrabbit is to download a binary release, but if you want to access the latest development version, you need to get the Jackrabbit sources and build them using the Maven 3 build environment.

The first step in building Jackrabbit is to clone the Jackrabbit sources from the Git source repository at

The default branch is named trunk (for historical reasons) and contains the reactor Maven project and a number of components in Maven modules. See the README.txt files within each subdirectory for a brief description of the according component.

There is also a sandbox directory hosted in Subversion with miscellaneous contributions that are not (yet) a part of the official Jackrabbit releases and the mostly outdated commons/.

Cloning the repository with Git

You need a Git client to access the Jackrabbit source repository. You can clone the main Jackrabbit source tree with the following command (or its equivalent in the client you are using):

git clone

The above checkout will create a subdirectory that contains the latest Jackrabbit sources.

Building the sources with Maven

Jackrabbit uses Maven 3 as the build system and the component sources are mostly organized according to the Maven Standard Directory Layout. The standard build environment is Maven 3 with the Java Development Kit (JDK) 11 for trunk.

See the Running Maven page and the related documentation on the Maven web site for instructions on how to use Maven. You may also want to check for Maven integration with your favourite Integrated Development Environment (IDE).

There are Maven project descriptors (POMs) within both the top level jackrabbit directory you checked out above and all the jackrabbit-something component subdirectories. The easiest way to build Jackrabbit is to use the “multimodule” setup within the top level directory:

$ cd /path/to/jackrabbit; mvn install

This will build and package all the component projects and place the resulting artifacts within your local Maven repository. You can also find the artifacts within the created target subdirectories of the component projects.
