If you already know how to use Fulcrum and simply want the latest binaries or source, you can get them from the Apache Mirror System.
Building Fulcrum from SVN is now very easy because it has been Maven-enabled. Before you begin, you'll need to check out the turbine-fulcrum SVN repository (if you are not familiar with the Apache SVN repositories, please refer to the documentation).
svn checkout http://svn.apache.org/repos/asf/turbine/fulcrum/trunk/
Please refer to the Maven 3 Getting Started document for instructions on how to install and use Maven.
From the root directory of the Fulcrum project (where you checked out the code to or unpacked a source distribution), simply run
mvn install
To build a local copy of the documentation, use this:
mvn site
Depending on your version of Maven, you may have various problems with the reports being generated, or you may run out of memory when you do a complete build. One approach to take is to turn off running unit tests
$ mvn site -DskipTests=true
$ mvn -pl parser,crypto site
