Crashed Eclipse

Yesterday, I crashed my Eclipse CVS.. uggghh!!. It was started when I want to install PHPEclipse plugin for syntax coloring and others add-on. I downloaded the file from sourceforge, and I use terminal for dropping the downloaded data into the eclipse plugins and features directory on
/etc/share/eclipse/..
(no root access using the gnome file browser).
And then I used the command
root@akbar:/mv /home/akbarkhrisna/Desktop/plugins/* /usr/share/eclipse/*
But it doesnt work, and it told me that the directory is not empty.. blah..blah..blah…, then I remember that I have to add some kinda property after the mv command.
I googled it, after sometime I ended up using -adviv or -viv command instead of using -f from this damn tutorial on the internet to force moving the directory contents. But, then it just erase my whole eclipse plugins directory!!! (amateur!!!)

As I would expected, I couldnt find my lost plugins directory anywhere.. and that leave me with one choice.. re-install it again.
I re-install the eclipse using:
root@akbar:/apt-get remove eclipse-platform
root@akbar:/apt-get remove eclipse-base
root@akbar:/apt-get install eclipse
And it works now.. thank god! even I have to check out my project again.
