I'm working on Eclipse Indigo on Ubuntu 12.04. I'm trying to completely uninstall Eclipse (with Synaptic Package Manager + "Mark for complete removal"), but when I reinstall it, I clearly see that it has kept all parameters, and history, which is what I'm trying to get rid of. I also tried
sudo apt-get purge eclipse rm -r ~/.eclipse/
as suggested here, no luck either. Any hint welcome!
