Ubuntu – Eclipse Kepler on 12.04

12.04eclipseinstallation

I am using Ubuntu 12.04LTS (32-bit). I am currently installing Eclipse Kepler using this post. I've finished the process but I can't get the eclipse display on the menu search. Currently, the eclipse icon is displayed along with its image, but the icon itself can't be clicked/entered. I have installed Oracle JDK 7 provided by this tutorial.

This I miss something that caused the icon/application to not run and/or cannot be clicked?

Delete any previous launcher for Eclipse you may have made, this will create a completely new one.

Run these commands:

# Installs gnome-desktop-item-edit, a useful GUI to configure .desktop files
sudo apt-get install --no-install-recommends gnome-panel

# Symlinks eclipse to /usr/local/bin, allowing you to launch it from a command line
# If eclipse is not in /opt, change this to point to your eclipse executable
sudo ln -s /opt/eclipse*/eclipse /usr/local/bin/eclipse

# Creates a new .desktop file in '/usr/share/applications'
sudo gnome-desktop-item-edit --create-new "/usr/share/applications/eclipse-ide.desktop"

Then, put these into the fields, leave others default (You can actually put whatever you want in these, except "Command"):

Name: "Eclipse IDE"
Command: Click the Browse button and find the eclipse executable file
Icon: Click the springboard icon (towards the top left), then browse to the file icon.xpm, in the same folder as the eclipse executable
- Note: The default Eclipse icon is very bad with Unity, you can't tell if it's launched or not. I personally use this icon here. Just choose this downloaded icon instead of the default icon.xpm
Comment: Anything you want, I put (from Wikipedia)

Eclipse is a multi-language IDE comprising a base workspace and an extensible plug-in system for customizing the environment.

Click "OK", then search the Dash for your new icon.

Create a file "eclipse.desktop" or similar, just be sure to have the .desktop extension.
Open File with a texteditor (gedit for instance)

paste following code into the file:

[Desktop Entry]
Version=1.0
Type=Application
Terminal=false
Exec=/home/path/to/eclipse/eclipse --clean -vmargs -Dfile.encoding=UTF-8 -Xmx1024m -Xms256m -XX:MaxPermSize=256m
Name=Eclipse JEE IDE
Icon=/home/path/to/eclipse/icon.xpm

Be sure to replace "/home/path/to/eclipse/" with your path to your eclipse installation folder.
Save the file
Make the file executable and copy it whereever you want an eclipse starter.

Happy Coding!

Ubuntu – Installing Eclipse Kepler

First of all, you need to check whether you have java installed on your system. You can check by using the command:

java -version

If java is not installed, then you should install it by doing

sudo apt-get install default-jre

Afterwards, download Eclipse from the download section of the official website (http://www.eclipse.org/downloads/). Remember to choose the correct package for your architecture (32bit or 64 bit). The package will have the name:

eclipse-standard-kepler-SR1-linux-gtk-x86_32.tar.gz

eclipse-standard-kepler-SR1-linux-gtk-x86_64.tar.gz

After you have downloaded the correct package, extract the eclipse.XX.YY.tar.gz using

tar -zxvf eclipse.XX.YY.tar.gz

switch to root user:

sudo -i

Copy the extracted folder to /opt

cp -r eclipse.XX.YY /opt

Create a desktop file in the location /usr/share/applications and install it:

gedit eclipse.desktop

Copy the following to the eclipse.desktop file.

[Desktop Entry]
Name=Eclipse 
Type=Application
Exec=eclipse
Terminal=false
Icon=eclipse
Comment=Integrated Development Environment
NoDisplay=false
Categories=Development;IDE;
Name[en]=Eclipse

Give the desktop file permission to be executed, run:

chmod +x eclipse.desktop

Run the following command to automatically install it in the unity:

desktop-file-install eclipse.desktop

Create a symlink in /usr/local/bin using

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

For an eclipse icon to be displayed in dash, eclipse icon can be added as

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