SVN: How do I link part of my source to another repository?

Say my trunk refers to Hibernate and I would like to use the source directly in my repository from sourceforge and whenever I do a svn u开发者_Python百科pdate it should also update hibernate from its source

How do I achieve this?

You should be able to do so with externals. Set them up with a command like this:

svn propset svn:externals dest-folder http://your-other-repository

You can find the documentation on externals in http://svnbook.red-bean.com/en/1.0/ch07s03.html
