7.Compiling the Mahout using maven.

 
smims@ubuntu:~$ cd mahout/trunk
smims@ubuntu:~/mahout/trunk$ mvn install 
...

But there is a error message.
[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------
[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?
[INFO] 1 error
...
To fix this, just re-install the jdk and install again. It works just fine.

 
smims@ubuntu:~/mahout/trunk$ sudo apt-get install openjdk-7-jdk
...
smims@ubuntu:~/mahout/trunk$ mvn install 
...

8.At the last few steps, it will automatic test some examples.
