Do you actually need to compile to both ? Or do you compile to bin, then instrument the classes
from bin into bin-clover ?


When not generating reports, only to bin.

I would do something like this

<condition property="classes.dir.for.tests" value="bin-clover" else="bin">
  <isset property="clover"/>
</condition>

<junit>
....
<classpath>
<pathelement location="${classes.dir.for.tests}"/>
</classpath>
</junit>
