Just downloaded the source code, trying to compile charm reforged using gradlew build i get this error:

`FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ':addMixinsToJar'.

Gradle 6 was detected but the mixin dependency was missing from one or more Annotation Processor configurations: [annotationProcessor]. To enable the Mixin AP please include the mixin processor artefact in each Annotation Processor configuration. For example if you are using mixin dependency 'org.spongepowered:mixin:0.8.2' you should specify: dependencies { annotationProcessor 'org.spongepowered:mixin:0.8.2:processor' }. If you believe you are seeing this message in error, you can disable this check via by adding disableAnnotationProcessorCheck() to your mixin { } block.
`

do you know how I can fix this?
