Humm, well I still get the same error. I think that is it the second
dependency that is giving the problem, not the project one. Here is
the new task and the error. Seems very strange that gradle jar works
fine, but play fails since a nonresolving dependency ought to be as
much of a problem for jar as for play. I guess I still don't
understand what is going on behind the scenes as all the task is
asking for is the basic information that is directly in the
build.gradle file, so resolving shouldn't really be needed.
Anyway, here is the error if you can think of any other reason why
this might be failing.
thanks,

task.project.configurations.default.files { artifact ->
print "${artifact.getClass()} ${artifact.name}
