Before you open an issue

• Are you using the latest Gordon version?
• Are you using the latest Gradle version?
• Are you using the latest Android Gradle Plugin version? If not, try updating. If you can't update your AGP version, you may have to use an older Gordon version that supports the outdated AGP version.
• Are you sure this is a bug?

Describe the bug
When using Gordon with Gradle 7.0 I'm getting this error:

Some problems were found with the configuration of task ':app:gordonDev' (type 'GordonTestTask').
  - Type 'GordonTestTask' property 'androidInstrumentationRunnerOptions$gordon_plugin' is missing an input or output annotation.

To Reproduce

1. Apply Gordon to an Android [app|library|feature] module.
2. Run the following gradle task: app:gordonDev
3. See error
