Hi,

I needed an info regarding svn and ant scripts.

I am using JDK 1.3.1. We are working on a project to migrate from CVS to SVN.
My task is to convert all ant build scripts to use svn.

I tried using SVNANT and got the below error. In the forums it is mentioned that SVNANT is compiled on JDK 1.5.

Is there any way I can use svn in ant scripts without using svnant? Or is there any older version of svnant which I can use in JDK 1.3.1 environment?

Thanks a lot for the help
