Thanks for that Gordon - thing is that is what I tried at first and it didn't work for me, it was finding the new rt.jar but not running the 1.4 compiler (ant was running in a 1.3 VM). However I didn't have any of the extdirs, source or target attributes set, but I don't think that would be the difference?
I do have it working now but it seems a bit hacky... thx, jamie > -----Original Message----- > From: Gordon Tyler [mailto:[EMAIL PROTECTED]] > Sent: 26 April 2002 16:14 > To: Ant Users List > Subject: Re: setting a specific compiler > > > Hi Jamie, > > I've gone through the same sort of hassle recently and this > is the solution > that I came up with based on a suggestion from Stefan Bodewig: > > Our main build environment is JDK 1.4 but there are parts of > the system that > must be compiled with JDK 1.3.
