the original question wasn't whether target/task are conditional (they
are). it was whether there's a way to test the availability of tasks.
there is. it's documented as:
built-in properties:
nant.task.* Each task available to nant has a "true" value, e.g.,
nant.task.copy
however, the DOCS ARE WRONG. the name of the properties is:
nant.tasks.*
the following works for me:
<!-- sadly, there needs to be this extra step for safety -->
<ifnot propertyexists="nant.tasks.nunit2" >
<property name="nant.tasks.nunit2" value="false" />
</ifnot>
<!-- main entry -->
<target name="test-task-presence" depends="run-when-nunit" >
<echo message="in main" />
</target>
<!-- conditional on task availability -->
<target if="${nant.tasks.nunit2}" name="run-when-nunit" >
<echo message="nunit is avail" />
</target>
