Bloop with Gradle and Silencer

This is a minimal recreation of an issue I encountered with Bloop and Gradle with scalaCompilerPlugins for setting scalac plugins

The Gradle project works fine

❯ ./gradlew test

BUILD SUCCESSFUL in 6s
3 actionable tasks: 3 executed

The bloopInstall task finishes

❯ ./gradlew bloopInstall

Deprecated Gradle features were used in this build, making it incompatible with Gradle 7.0.
Use '--warning-mode all' to show the individual deprecation warnings.

bloop test fails due to unsilenced deprecation error
