You can set java_home at runtime in windows. If you're compiling multiple projects with two version of java it is best not to set java_home as environment variable.
There are multiple ways of achieving the same outcome...here are two ideas. First, set java_home in a batch file to kick-off the build process and set java home. Create a .bat file and add the following content. set JAVA_HOME=<to directory path of java> call ant -f build.xml Second, create a build.properties in the same directory as build.xml and add the following content. java.home = <to directory path of java> Remember to load the properties file in your build.xml i.e. <property file="build.properties"/> Hope this helps. -----Original Message----- From: Knuplesch, Juergen [mailto:[EMAIL PROTECTED] Sent: Wednesday, May 14, 2008 9:35 AM To: Ant Users List Subject: AW: how to change the property value at run time Thats just the special thing about ANT-properties: You can not change them, for good reasons.
