You could have a look at its source
http://svn.apache.org/viewvc/ant/core/trunk/src/main/org/apache/tools/an
t/taskdefs/optional/clearcase/ClearCase.java?view=annotate
Line 134 is
exe.setWorkingDirectory(aProj.getBaseDir());
aProj is initialized on 130
Project aProj = getProject();
That method is inherited from ProjectComponent (Task base class extends
that) which returns the project reference needed for logging, properties
etc.
You havent set that value.
ckout.setProject(...);
