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.

Thats just the special thing about ANT-properties: You can not change them, for good reasons.
But JAVA_HOME does not look like an Ant-property. What do you want to do?

Betreff: how to change the property value at run time
Hi All,
I need to change the value of a specific property at run time. Can somebody please let me know how I can do that.
Let's say the property name is "JAVA_HOME" and suppose I want to change the value of that property to "d:\install"
Please help.
Regards,
Irfan
