How can I install Eclipse and Java SDK on Ubuntu?

Question

I have just downloaded Ubuntu. It runs much faster than my Windows XP. But, I don't know how I can set up Eclipse v4.2 (Juno), or the Java SDK. I am currently developing in the Lightweight Java Game Library, so I might need some help with that too.

Answer 1

Execute this in your terminal:

sudo apt-get install eclipse
sudo apt-get install openjdk-6-jdk openjdk-6-source openjdk-6-demo openjdk-6-doc openjdk-6-jre-headless openjdk-6-jre-lib 

The first one installs Eclipse (you will be asked to enter your password), and the second one installs all the Java stuff you may need!

Answer 2

Don't install Eclipse from the Linux repositories. These repositories may not be up-to-date with the last versions released by Eclipse. A better approach is to follow the instructions in this answer from Ask Ubuntu . For Java programming, make sure you have a JDK and a JRE installed

apt-get install openjdk-7-jdk openjdk-7-jre

You can download whatever Eclipse Java IDE version suits you best from the Eclipse website ( link to the Eclipse v4.4 (Luna) release ).

Answer 4

You don't really install Eclipse - you just download the folder and run the program - just like in windows. Just make sure you download a Linux version.

To install JDK, type:

sudo apt-get install openjdk-6-jdk

You will be asked to type in your password before the installation will begin. You could also install JDK through the software manager.

Answer 5

You might want to consider installing Sun Java 6 for your Java programming needs; correct me if I'm wrong, but I feel that OpenJDK may still be lacking in some libraries and compatibilities.

If you want to install Java 6 on your machine, you can follow this guide on how to do so: https://codingforme.wordpress.com/2012/05/14/installing-oracle-java-jdk-6-or-7-on-ubuntu-12-04/

Answer 6

Just remove all Eclipse packages typing:

sudo apt-get autoremove eclipse

And with tab find all installed Eclipse packages.

Do the same with Java.

I just reinstalled Eclipse with the command

sudo apt-get install eclipse

which also contains Java.
