adding user defined libraries to SVN

I am developing a project for which I have used a number of external libraries (in jar format). I have added all of the external jars I have downloaded and added to the build path to our version control (subversion) as well.

However it has recently come to my attention that a number of the libraries are not in the SVN tree. I have looked into it a bit, and these are the libraries that I have created as user defined libraries and added to the build path in that way, following the instructions on the respective web pages. When I right click on them in Eclipse, I don't see the options to add them to the version control. So I decided to export them to the lib folder 开发者_开发百科I have on the SVN tree. I am not sure if it's the right way of solving this problem, would appreciate som help on the matter.

I am not sure if it's of any help but the packages in question are: Commons Math, JFreeChart and JCommons.

Have you considered using something like Maven or Ivy for your external dependencies?
