Installing Eclipse in Ubuntu 13.10

Adapted answer from Shubhmay and TimD on askubuntu on installing Eclipse.

1. Extract the eclipse.XX.YY.tar.gz file: tar -zxvf eclipse.XX.YY.tar.gz

2. Copy the extracted folder to /opt: sudo cp -r eclipse /opt

3. Create a desktop file gedit eclipse.desktop

4. copy the following to the eclipse.desktop file

    [Desktop Entry]
    Name=Eclipse 
    Type=Application
    #Exec=eclipse
    Exec=env UBUNTU_MENUPROXY=0 eclipse # for menubar bug in 13.10
    Terminal=false
    Icon=eclipse
    Comment=Integrated Development Environment
    NoDisplay=false
    Categories=Development;IDE;
    Name[en]=Eclipse
   

5. Execute the following command to automatically install it in the unity: sudo desktop-file-install eclipse.desktop

6. Create a symlink in /usr/local/bin using

   cd /usr/local/bin
   ln -s /opt/eclipse/eclipse
   

   according to user ortang:

   Use the eclipse version when creating a the symlink (eg: ln -s /opt/eclipse/eclipse /usr/local/bin/eclipse42), and use Exec=eclipse42 at the desktop entry. That way you will be able to install multiple different versions of eclipse

7. For eclipse icon to be displayed in dash, eclipse icon can be added with

   cp /opt/eclipse/icon.xpm /usr/share/pixmaps/eclipse.xpm
