The most recent Subclipse Eclipse plugin (v1.8.x) requires SVN/JavaHL 1.7.x; however, running
sudo apt-get install libsvn-java
doesn’t quite get you there in Ubuntu.
Fortunately Dominik Stadler has created a PPA you can add to your software sources.
Before you continue, uninstall your existing libsvn-java:
sudo apt-get purge libsvn-java
Then proceed to add the PPA and reinstall the package:
sudo add-apt-repository ppa:dominik-stadler/subversion-1.7 sudo apt-get update sudo apt-get install libsvn-java
You may also need to update your eclipse.ini to include
/usr/lib/x86_64-linux-gnu/jni depending on your system)
You can now upgrade Subclipse to 1.8.x
.. or save yourself the hassle and move to git
