Subject Re: Unable to create junit task with ant 1.6.2 & junit3.8.1
Date Fri, 29 Oct 2004 15:33:13 GMT

The JUnit task is located in ANT_HOME/lib.  If you want to use the JUnit task
without putting junit.jar in ANT_HOME/lib or $user.home/.ant/lib, then you'll
have to remove the junit task from ANT_HOME/lib and added manually to your
classpath just as you are manually adding junit.jar to your classpath.

Short answer, both the junit task and library need to be loaded in the same
classloader.  I always put jars required by tasks that come with Ant in
$user.home/.ant/lib so that when I upgrade Ant, I don't have to worry about
remembering not to delete extra jars added to ANT_HOME/lib.
