Java Developer Kit (JDK)

You will need a JDK 56.0+ (J2SE 1.5.0Java SE 6+) or compatible JDK to build Apache Geronimo. It is recommended you use SUN's implementation, or something compatible like Apples implementation. Other JDK vendors implementations may work, but use at your own risk.Newer JDK versions (like for Java 6) probably won't work, as the server build will probably fail with a message complaining about it. Its possible to disable that check and play with a newer JDK version, but if you want the build to pass, you are better off just using a Java 5 JDK

Apache Maven 2

To execute the build process you need to have Apache Maven version 2.0.9 (or newer) installed.
