I am trying to specify the classpath to the javac task by using the "classpath" attribute. But when I run Ant, it also includes the classes and jars in the "classpath" environment variable. I donot want ant to include the classpath environment variable. So as the documentation specifies I tryed to specify "-Dbuild.sysclasspath=ignore" to Ant to make it ignore the environment classpath. But this does not work. Has anybody else run into this problem and solved it?
