@Guardiola31337 I don't see our versions for jacoco.ant or lint-gradle in dependencies.gradle - any ideas? Updated otherwise

• com.google.auto.value:auto-value [1.5 -> 1.6.2]
  https://github.com/google/auto

For now we can bump auto-value to 1.5.4 because starting Auto Value 1.6 there are some breaking changes that'd need extra work (the annotations are in a different artifact) 👀

@AutoValue, @AutoAnnotation, @AutoOneOf, and @Memoized are now in a separate artifact, auto-value-annotations. This allows users to specify the annotations in compile scope and the processor in an annotation processing scope, without leaking the processor to a release binary. To upgrade to this version of auto-value, you'll need to add this new artifact as a dependency. (0c488d7)

Further instructions in https://github.com/google/auto/blob/master/value/userguide/index.md#in-pomxml

Note: If you are using a version of Gradle prior to 4.6, you must apply an annotation processing plugin as described in these instructions.

If we don't explicitly define those, don’t worry. Should be some transitive dependencies that brought in somehow. jacoco is 0.8.1 though 🤔
