We recommend downloading the jMonkeyEngine SDK - but of course you can also build the jMonkeyEngine yourself from the sources. In this case, you need the Subversion file version system installed (svn).
svn checkout http://jmonkeyengine.googlecode.com/svn/trunk/engine jme3
ant jardist/libs/*ant javadoc dist/javadoc directory.ant rundist/lib directory on the classpath.com.jme3.app.SimpleApplication. For a detailed description of the created jar files see this list.
