I have a small set of lightning components and related apex classes that I'm trying to deploy using ant. The first deployment was fine. I had to make a change and updated the apex class that has all the test methods, including creating setup data, and now the any deployment fails each time. It looks like it is executing old test classes. I tried an undeploy, but the tests are all run first and so that fails also. I thought the migration tool would recognize the 100% coverage from my demo / trial org when deploying, but I guess not? Not sure how to get updated apex deployed now or even just delete the problem classes.

Thanks.
