Create a case class in modules/directives/src/main/scala/scala/build/preprocessing/directives/ extending one of:
HasBuildOptions — produces BuildOptions directlyHasBuildOptionsWithRequirements — produces BuildOptions with scoped requirements (e.g. test.dep)HasBuildRequirements — produces BuildRequirements (for //> require)Annotate: @DirectiveLevel(SpecificationLevel.EXPERIMENTAL), @DirectiveDescription("…"), @DirectiveUsage("…"), @DirectiveExamples("…"), @DirectiveName("key") on fields.
Companion: val handler: DirectiveHandler[YourDirective] = DirectiveHandler.derive
Register in modules/build/.../DirectivesPreprocessingUtils.scala in the right list: usingDirectiveHandlers, usingDirectiveWithReqsHandlers, or requireDirectiveHandlers.
Regenerate reference docs: ./mill -i 'generate-reference-doc[]'.run
CLI options always override directive values when both set the same thing.
