How to get rid of it?
First of, we need to install some libraries:
sudo apt-get install libsvn-java
Once this is done, we need to tell JVM (Java Virtual Machine) to include the path to our new libsvnjavahl-1.so file, when searching for extensions. We can do this in the eclipse configuration file. It is located inside the directory in which you installed Eclipse and is called eclipse.ini.
Find the line -vmargs and after it (in a new line) add this one:
Restart Eclipse and you’re done.
Tested on Eclipse Galileo (3.5.2) through all latest releases on Ubuntu 10.04 and onward.
