Trying to run

$ ant -Djunit.suite=KernelSuite.class runtests

Results in the following error:

BUILD FAILED
file:/var/ccm-devel/dev/vadim/dev/build.xml:1241:
 Could not create task or type of type: junit.

I have junit.jar available at the following location:

$ rpm -ql ccm-config-libs | grep junit.jar
/usr/share/java/junit.jar

The only place where the /usr/share/java directory is mentioned in
$CCM_DEVEL_HOME is in $CCM_DEVEL_HOME/ccm.classpath.  However,
$CCM_DEVEL_HOME/build.xml contains no references to ccm.classpath.
Thus, junit.jar is never added to the classpath.

The problem goes away if I do:

$ env CLASSPATH=$CLASSPATH:/usr/share/java/junit.jar \
  ant -Djunit.suite=KernelSuite.class runtests
