The Apache Maven project management framework provides Sakai with "a set of build standards, artifact repository model and a software engine that manages and describes projects" (Better Builds, p. 22). As part of the installation process you will use Maven as a build tool in order to compile, test and deploy Sakai to a servlet container such as Apache Tomcat.

(warning) Maven 2.2.1 is the recommended version for performing Sakai 2.7 builds; Maven 2.0.10 is the minimum version.
(minus) Maven 3.0 is currently NOT compatible with Sakai 2.7.

You can download Maven at

http://maven.apache.org/download.html

Extract the distribution archive into your installation directory of choice, e.g. /opt/maven/apache-maven-2.2.1. Confirm that you have installed the correct version of Maven and can start it by issuing mvn --version from the terminal. At this point your environment is prepared to build and deploy the Sakai source code.

mvn --version
