Maven, JUnit and Dagger - Dagger module could not be loaded - maven

Question

Note: I am building/testing via command line only.
I am running into an issue using Dagger, and have been able to reproduce the same issue in a very small test project. When trying to use Dagger in a unit test, I get the following error while running 'mvn clean test':
sanity(com.mycompany.app.AppTest): Module adapter for class com.mycompany.app.AppTest$TestModule could not be loaded. Please ensure that code generation was run for this module.
In the application, Dagger is compiling/building just fine, and injection is working great. The only issue is with the unit tests, and I feel that the unit tests arent picking up the results from the dagger-compiler, but am not sure how to test/fix this.

Aha - apparently annotation processing was completely turned off in an earlier commit, and I completely missed this line in the pom:
<compilerArgument>-proc:none</compilerArgument>
