[rules-users] Compile Challenges December 20, 2009

[Geoffrey De Smet]

Hi Pete,

It's a jdk/maven setup problem I think.
Can you try, these commands (without the $):

$ echo %JAVA_HOME%
=> should give something like C:\... and it should be a JDK, not a JRE


$ java -version
java version "1.6.0_16"
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Java HotSpot(TM) Server VM (build 14.2-b01, mixed mode)

$ mvn --version
Maven version: 2.0.9
Java version: 1.6.0_16
OS name: "linux" version: "2.6.31-16-generic" arch: "i386" Family: "unix"

$ javac -version
javac 1.6.0_16



See "Installation instructions" on the bottom of this page:
   http://maven.apache.org/download.html
on how to make sure maven works properly :)

With kind regards,
Geoffrey De Smet
