Anyone know if its possible to declare the various static/type checking at the global level (whole project) instead of having to annotate every file? Like maybe in the config YML file or something? https://docs.grails.org/latest/guide/staticTypeCheckingAndCompilation.html

This seems not to be possible. See here: https://stackoverflow.com/questions/61483866/grails-typechecked-compilestatic-grailscompilestatic/61485749#61485749
