I am assuming you have already installed eclipse. If not see: http://purvag.com/blog/?p=226
I would suggest installing subversion 1.6.x since there are few issues with 1.8.x. In eclipse:
Go to Help->Install New Software
Click Add. Copy the following URL in Location box:
On next screen select the required packages.
Click next and follow the instructions, and you are done.
If you get following error:
Failed to load JavaHL Library. These are the errors that were encountered: no libsvnjavahl-1 in java.library.path no svnjavahl-1 in java.library.path no svnjavahl in java.library.path java.library.path = /usr/lib/jni/
Close eclipse and run following command on terminal.
sudo apt-get install libsvn-java
Edit eclipse.ini file.
sudo nano /usr/lib/eclipse/eclipse.ini
Add following two lines after -vmargs
save and close
