After upgrading ubuntu, Eclipse has been upgraded to 3.8. Now, Eclipse does not start anymore. I know that at least one plugin is not compatible with 3.8. But I don't know how to remove it, without the GUI.

So, how can I remove a plugin from the command line? The log of eclipse can be found here:

by "Eclipse has been upgraded" you mean - you upgraded it, right? are you running a 64bit OS? collisions between a 64bit JVM and a 32bit eclipse distribution (installed absently) could cause this, as mentioned here. try and add -Djava.library.path=/usr/lib/jni to the VM arguments listed in eclipse.ini and see if that does it. – Eliran Malka Oct 19 '12 at 20:16
one more - if that doesn't help, try and remove the ~/.eclipse directory altogether, as old files from previous installations may be kept there and interfere with newly installed versions. – Eliran Malka Oct 19 '12 at 20:20

OK, this case proved to be really simple. Since the eclipse plugin that was giving errors was installed through the package manager, I could obviously also uninstall it there. Removing it, fixed the problem.
