External libraries are not shipped with Ant.
See http://ant.apache.org/manual/install.html#librarydependencies
Comment 5 Michal Jacykiewicz 2005-02-08 10:46:17 UTC 
I know that. I've got Junit installed.

jacykm@leopard:/tmp/antjunit> ls -l $JUNIT_HOME/junit.jar
-rw-r--r--    1 jacykm   ndseng     121070 Sep  4  2002 /phoebe_home/jacykm/bin/
tools/junit3.8.1/junit.jar
jacykm@leopard:/tmp/antjunit>
Comment 6 Jan Mat 2005-02-08 10:49:13 UTC 
That directory is not loaded by Ant.
1: place junit.jar in ${user.home}/.ant/lib
2: load that jar using -lib option
Comment 7 Michal Jacykiewicz 2005-02-08 11:02:27 UTC 
Why it isn't?
In that case that <classpath> within <taskdef> means?

<taskdef name="junit" classname="org.apache.tools.ant.taskdefs.optional.junit.
JUnitTask">
    <classpath refid="runtimelibs"/>
</taskdef>

Where
    <path id="runtimelibs">
        <pathelement location="${junit-dir}/junit.jar"/>
    </path>
Comment 8 Steve Loughran 2005-02-08 12:57:03 UTC 
Classloaders, that's why. Ant has a boot classloader (ant-launcher) that then
loads everything else, including ~/.ant/lib and anything with -lib on the
commandline. And the classpath, unless you say -noclasspath. ant-junit.jar is
loaded in that main classloader, so cannot see junit.jar. Even your
redeclaration wont help, as the one in the main classloader gets in there first.

you need to remove ant-junit.jar from your main ant library and include in the
taskpath for the redeclaration, so it shares the classloader with junit. Or pass
in the dir containing junit.jar as a -lib options.
