Probably. NoClassDefFoundError errors can be confusing. This can happen if the class inherits from a missing class or there is a static field of a missing class. Check the unfiltered logs. There might be more information.
Even in the unfiltered logs I can't see more. It seems that excluding .measurement also exludes analytics classes. I have no idea why.
Is it possible to enable additional logs so I can see which classes are exactly removed with the #ExcludeClasses attribute?
