Please find attached files: build.xml, output of ant -v and ant -diagnostics. If I am doing something wrong, please change this issue to request for enhancement to the documentation (e.g. taskdef, classpath, junit, optional tassks). This issue is releated to bugid#33428.
Created attachment 14205 [details] File build.xml which fails.

External libraries are not shipped with Ant. See http://ant.apache.org/manual/install.html#librarydependencies
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>
That directory is not loaded by Ant. 1: place junit.jar in ${user.home}/.ant/lib 2: load that jar using -lib option
Why it isn't? In that case that <classpath> within <taskdef> means? <taskdef name="junit" classname="org.apache.tools.ant.taskdefs.optional.junit. JUnitTask"> <classpath refid="runtimelibs"/> </taskdef> Where <path id="runtimelibs"> <pathelement location="${junit-dir}/junit.jar"/> </path>
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.
