NetBeans IDE 6.7.1 Ant脚本变量

Question

How do I get the location of rt.jar in my Ant script with NetBeans without editing my project.properties? ${java.home} is returning the location of the jre folder and not the jdk folder.

I know that I could easily add a value to project.properties but I don't want to. I also know that I could easily just modify the path whenever I switch computers but I would prefer not to do that either.

Edit: Maybe ${java.home} is the best solution and I should just fix my computers environment variables correctly.

Edit2: I just realized that java.home is not the same as JAVA_HOME. More information: http://javahowto.blogspot.com/2006/05/javahome-vs-javahome.html

Answer 1

Do you have JAVA_HOME set? If so does it point on a JDK? From the Ant documentation :

When you need JDK functionality (such as for the javac task or the rmic task), then tools.jar must be added. The scripts supplied with Ant, in the bin directory, will add the required JDK classes automatically, if the JAVA_HOME environment variable is set.
