Install eclipse under Ubuntu

The version I'm using is up to date.
Ubuntu 14.04

Steps:

1, install the configuration Java environment, because Eclipse uses Java so needs the Java Runtime Environment

download installation jdk
$sudo apt-get Install OPENJDK-6-JDK

in the current system $sudo Update-alternatives--display java
Install JVM path
$sudo update-alternative s--install/usr/bin/java Java/usr/lib/jvm/java-1.6.0-jdk/bin/java
Replace the system JVM
$sudo update-alternatives–config java< /strong>
Configure environment variables (  This can choose not to do)
$vim/etc/profile
Add the following lines:    
Export JAVA_HOME=/USR/LIB/JVM/JAVA-1.6.0-OPENJDK

Export classpath=.: $JAVA _home/lib: $JRE _home/lib: $CLASSPATH
Export path= $JAVA _home/bin: $JRE _home/bin: $JAVA _home: $PATH

Run $source/etc/profile make the configuration effective immediately

Verify that the configuration is complete
$echo $JAVA _home
$java-version
2. Download eclipse

Download the Linux version of Eclipse IDE for Java EE developers from official website http://www.eclipse.org/downloads/

Eclipse-sdk-3.7.2-linux-gtk.tar.gz

3, unzip
$ tar-zxvf Eclipse-sdk-3.7.2-linux-gtk.tar.gz
Extract is an Eclipse folder
4, move the folder to the installation directory
$ sudo mv Eclipse/ usr/local/
5, start Eclipse
$/usr/local/eclipse/eclipse
6, create a desktop link
$ sudo su
# vim/usr/share/applications/eclipse.desktop
Writes the following
[desktop Entry]
Name=eclipse
Comment=eclipse SDK
Encoding=utf-8
Exec=/usr/local/eclipse/eclipse

You can see the Eclipse icon under application-programming when you're done.
