VirtualBox - Ubuntu - create and share a SharedFolder in Ubuntu VM

Environment:
OS: Ubuntu 14.04 on Guest VM
VirtualBox: 4.3.6 on Host Machine Windows 7

Steps to follow:

• Need to make sure "Virtualbox Guest Additions" is installed (see Resource-01)
• Creating a folder in Host Windows
• Create a 'Shared Folder' in VirtualBox
1. Start the VM and go to 'Devices > Shared Folders Settings...'
2. On Settings dialog, click on 'Shared Foldrers' which will show existing shared folders at right (see pic-01)
3. Click on 'Add new shared folder definition' icon (see pic-01)

   

   Pic-01

4. Specify 'folder path', 'Folder Name' (see pic-02) and click 'Ok' 

   

   Pic-02

5. Click 'Ok' on Settings dialog

• Prepare Ubuntu VM


• Create a folder where host folder with be mapped to 
• Run mount command - "sudo mount -t vboxsf -o uid=$UID,gid=$(id -g) SharedWithVMs ~/SharedWithVMs". In this case shared folder in VirtualBox and folder in Ubuntu VM having same name

Eclipse - Ubuntu - Setup - Install Eclipse on Ubuntu OS

Environment:
OS: Ubuntu 14.04 64-bit
Eclipse: Luna 4.4 64-bit


Install Eclipse:

• Make sure Java is installed. I have another post how to do so (see Resource-01)
  
• Download Eclipse installer. URL="http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/luna/R/eclipse-jee-luna-R-linux-gtk-x86_64.tar.gz"
  
• Extract the file.
  using command in terminal: tar -zxvf eclipse-jee-luna-R-linux-gtk-x86_64.tar.gz
  using Archive Manager UI tool
  
• Copy extracted folder to "/opt".
  Command: sudo mv eclipse /opt
  

Start eclipse:

• From terminal
1. Open terminal (shortcut ctrl+alt+t)
2. Go to location "/opt/eclipse"
3. Run executable "./eclipse"
   
• From file browser
1. Open file browser
2. Go to location "/opt/eclipse"
3. Double click on eclipse icon
   
• Create desktop file and install. This will help opening eclipse from unity launcher (see Resource-02, Resource-03)
1. Create eclipse desktop file
   Command: "gedit eclipse.desktop"
   
2. Type following the file
   
   [Desktop Entry]
   Name=Eclipse Luna
   Type=Application
   Exec=/opt/eclipse/eclipse
   Terminal=false
   Icon=/opt/eclipse/icon.xpm
   Comment=Java Integrated Development Environment
   NoDisplay=false
   Categories=Development;IDE;Name[en]=Eclipse Luna
   
   Note: See Note-01, Note-03 for more information if desktop file not behaving as expected
   
3. Execute the desktop file
   Command: "sudo desktop-file-install eclipse.desktop"
   
4. Give eclipse permission to modify osgi file
   Command: "sudo chown -R $USER:$USER
   /opt/eclipse/configuration/org.eclipse.osgi"
   
5. Give desktop file permission to execute (see Note-02)
   Command: "chmod a+x eclipse.desktop"
   

Notes:

1. If icon is not displayed - icon file name cannot have extension unless full path is specified
2. If desktop file is not displaying name mentioned in file. Showing 'eclipse.desktop' instead of 'Eclipse Luna' - desktop file's execution permission not set.
3. Getting 'There was an error launching the application' - value mention in desktop file for Exec is not correct
