Prediction for not existing checkout impossible #152

Open nichmoe opened 7 months ago

nichmoe commented 7 months ago

Bug: You are not able to test a new GitCheckout, without deploying it.

Reproduction: Add a new batou_ext.git.GitCheckout to the deployment and test it with the -P prediction option. The deployment prediction fails, because of a (correctly) missing folder.

Expectation: A prediction doesn't fail, because the component could not change the file system.

Traceback:
