Start with the stack trace at io.appium.java_client.remote.NewAppiumSessionPayload.java:98 and reproduce it from scr.main using Appium Java client 7.0 with Selenium server 3.12.0. Confirm the dependency mismatch causing the missing class and verify that AndroidDriver can create a session without the NoClassDefFoundError.
