title: Installing maven2 without openjdk
body: <p>by default ubuntu comes with openjdk. I installed jdk from sun, and removed openjdk, but with openjdk I had to remove maven2. How can I reinstall it without installing openjdk?</p>
  
  <pre><code>~$ java -version
  java version "1.7.0_03"
  Java(TM) SE Runtime Environment (build 1.7.0_03-b04)
  Java HotSpot(TM) Server VM (build 22.1-b02, mixed mode)
  
  ~$ sudo apt-get install maven2
  (...)
  The following extra packages will be installed:
  (...)
  openjdk-6-jdk openjdk-6-jre openjdk-6-jre-headless
    openjdk-6-jre-lib
  (...)
  The following NEW packages will be installed:
  (...)
  openjdk-6-jdk openjdk-6-jre openjdk-6-jre-headless
    openjdk-6-jre-lib
  </code></pre>
  
  <p>Any help appreciated, I have googled a lot and I haven't found any solution :/</p>
