Configure the eclipse development environment in Ubuntu

I believe most people will configure Eclipse in Windows. So, what about replacing the system with Ubuntu?

I found that the default Jdk in Ubuntu is Openjdk. I don't know if it was automatically installed with apt-get. As a result, the development in Eclipse is greatly unsuitable because the standard Jdk is used in the past.

1)

Query java version terminal input: java-version

So how to configure your Ubuntu and Jdk?

First, www.sun.com, download the Linux JDK, I download this JDK: jdk-7u3-linux-i586.tar.gz.

Decompress tar zxvf jdk-7u3-linux-i586.tar.gz

Modify system environment variables

 
 

  
  
Sudo vi/etc/environment
  
  
 
  
  
PATH = "/home /... /Download/jdk1.7.0 _ 03/bin"
  
  
 
  
  
CLASSPATH = "/home /... /Download/jdk1.7.0 _ 03/lib"
  
  
 
  
  
JAVA_HOME = "/home /... /Download/jdk1.7.0 _ 03 /"
 
 

At this point, if your UBUNTU has not installed Openjdk, you can skip the following text.

2 optional)

Let's modify Jdk and enter the following code:

 
 

  
  
Sudo update-alternatives-install/usr/bin/java/home /... /Download/jdk1.7.0 _ 03/bin/java 300
  
  
 
  
  
Sudo update-alternatives-install/usr/bin/javac/home /... /Download/jdk1.7.0 _ 03bin/javac 300
 
 

Statement: where... Represents my working directory

Select the system default Jdk

 
 

  
  
update-alternatives –config java 
 
 

After the selection, let's check the downloaded java version.

 
 

  
  
java -version  
  
  
 
  
  
java version “1.7.0_03″  
  
  
 
  
  
Java(TM) SE Runtime Environment (build 1.7.0_03-b04)  
  
  
 
  
  
Java HotSpot(TM) Server VM (build 22.1-b02, mixed mode)  
 
 

3)

Of course, we must first download the Linux version of Eclipse. Http://www.eclipse.org/downloads/, download and directly decompress it.

Another way is to enter sudo apt-get install eclipse in the terminal.

Now that jdk has been configured, configure Eclipse

Select

Add your JDK to the right of Window-perferences-java-installed JRES

OK, you are done !!!

Go in and have a look.
