Setting JAVA_HOME when running Ant from Java

Question

The reason is long and boring, but I need to run an Ant script to compile Java 1.5 code from a Java 1.4 app. I keep getting this error, though:

BUILD FAILED         


        

Answer 1

Another way to make this work is to add 'tools.jar' to your classpath. The javac compiler is contained within this jar.

java -cp $JAVA_HOME/lib/tools.jar ...
