Started exploring Espresso 2.0, but seem to have run into a hiccup. I cannot get the tests to successfully run against any project which includes Dagger. When I run the tests I get the following Exception (entire stacktrace at the end):
java.lang.NoClassDefFoundError: com/pdt/daggerexample/model/DaggerExampleAppModule$$ModuleAdapter$ProvideMySingletonProvidesAdapter
The application runs when not running from the AndroidInstrumentationTest.
Here are some of the relevant files, I've also uploaded the project to github to allow for a quicker checkout/reproduction https://github.com/paul-turner/espressoDaggerExample.
