| Detecting JDK Version using ANT | Detecting JDK Version using ANT 2005-06-15 - By Zarar Siddiqi
Thank you all.
${ant.java.version} and ${java.version} yield two different values. 1.5 and
1.5.0_01, respectively.
I'm assuming ${ant.java.version} is the version Ant is using in case there
are multiple JDK's installed on the system and ${java.version} queries the
JAVA_HOME variable.
Am I correct?
Thanks again.
