How to install Eclipse 4.2 on Ubuntu 12.04
Since the Eclipse packages in the Ubuntu repositories are out of date, if we want to install latest releases, we are going to have to do it manually. You can just download the tar.gz file fromeclipse.org.
  1. Download Eclipse. I got eclipse-jee-juno-SR1-linux-gtk.tar.gz
  2. Extract it by executing a command line
    tar -xzf eclipse-jee-juno-SR1-linux-gtk.tar.gz
    Or with Archive Manager extraction.
  3. Move extracted eclipse folder to /opt/ folder
    mv eclipse /opt/
    sudo chown -R root:root /opt/eclipse
    sudo chmod -R +r /opt/eclipse
  4. Create an eclipse executable in your user path
    sudo touch /usr/bin/eclipse
    sudo chmod 755 /usr/bin/eclipse
    Create a file named eclipse in /usr/bin/ with your preferred editor (nanogeditvi…)
    Copy this into it
    #!/bin/sh    
    export ECLIPSE_HOME="/opt/eclipse"
    ECLIPSE_HOME/eclipse*
    And save the file
  5. Create a Gnome menu item
    Create a file named eclipse.desktop in /usr/share/applications/ with your preferred editor (nanogeditvi…)
    Copy this into it
    [Desktop Entry]
    Encoding=UTF-8
    Name=Eclipse
    Comment=Eclipse IDE
    Exec=eclipse
    Icon=/opt/eclipse/icon.xpm
    Terminal=false
    Type=Application
    Categories=GNOME;Application;Development;
    StartupNotify=true
    And save the file
  6. Launch Eclipse
    /opt/eclipse/eclipse -clean &
  7. Now you can Lock Eclipse to the launcher bar by clicking right button on Lock to Laucher
