Subject Re: Want to build under multiple JDKs
Date Fri, 07 Jan 2005 08:24:52 GMT
Hello Scott, Dick,

as usual a look at the manual can help. [1]

The answer is to use the fork attribute of the javac task, and specify 
the executable.

<javac fork="true" executable="c:/jdk1.3/bin/javac.exe"/> would do for 

(of course in real life you will use properties to tell ant where javac 
of JDK 1.3 is installed.)
