Hello Paul! That explains all the - at least to me - strange behavior.
I also saw in the doc Bob pointed me to that there is a grape resolve command to check the transitive dependencies of a grape. So no need to set up a dummy script for this and delete the ~/.groovy/grapes directory and re-fetch the jars. Thanks again to all involved here.

Weitere Informationen, warum dies wichtig ist, finden Sie unter https://aka.ms/LearnAboutSenderIdentification ] If you look up the Javadoc for Grab, you will see that it can be on more things than just an import. It can be on a type, a method, a field, a local variable and so forth. It can't be used on a single statement. The suggestion for placing it on an import statement is really just a suggestion. It is often preferred to place it there rather than on a field or single method because it will be applicable for the whole script regardless of where you place it - you wouldn't want someone to think the @Grab was only applicable for a particular method for instance. If you just have a single println and nothing else, that is a local variable called "println" which will come from the binding and have value null since you haven't defined any value.
