Option1 : You may want to try resetting JAVA_HOME to appropriate path (1.4 or 1.3) just before starting the task..
Option2 : (prefered) or to be more spefic..you can specify the full path say C:\myjdk1.4\bin\javac.exe .. the same way one would use C:\VisualCafe\Bin\sj.exe .. I use symantc compilers from other IDEs this way..] . The appropriate versions of javac.exe would *include* corresponding versions of jdk (rt.jar and the stuff..) - this method would not affect other processes running in the system that may be dependent on JAVA_HOME .

I haven't tried it as yet, but I am going to use the executable attribute of the javac task and see if things work ok. Will let you know if stuff works fine. -----Original Message----- From: John Lindwall [mailto:[EMAIL PROTECTED]] Sent: Saturday, November 30, 2002 7:01 AM To: 'Ant Users List' Subject: RE: changing JAVA_HOME dynamically I've got the same issue! I've got a top-level build.xml that builds a project that requires jdk 1.3 for compiling. This works fine. I'd like this top-level build.xml to invoke a child build.xml that builds a project that requires jdk 1.4.1 for compiling. JAVA_HOME for the build environment is set to the 1.3 JDK so the top-level build uses 1.3 as expected. The child build fails since it uses JDK 1.4 features and ant is using JDK 1.3 for the compiles. How can I force the child build to use JDK 1.4? Here's the target in the parent build.xml that invokes the child build.xml. <target name="build-oe" depends="init" description="Executes the build for OE" > <ant dir="oe" antfile="build.xml" target="build" inheritall="false" /> </target> -----Original Message----- From: Euan Guttridge [mailto:[EMAIL PROTECTED]] Sent: Thursday, November 28, 2002 5:05 AM To: '[EMAIL PROTECTED]' Subject: changing JAVA_HOME dynamically I have two Ant builds. One requires JDK1.3.1 and the other JDK1.2.1. Is there a way to change the JAVA_HOME from within the Ant scripts? I'd like avoid writing a shell script just to do this..
