Answer 1

A NoClassDefFoundError exception usually suggests that you're missing a dependency.

This is not stated anywhere in the documentation, but it's not enough to just include the MindSphere SDK to your project alone; you also need some additional dependencies to make it work. Try adding the following to your Gradle/Maven build scripts:

org.apache.httpcomponents:httpclient:4.5.12
com.auth0:java-jwt:3.10.2

They're available in Maven Central.
