gradle clean build fails

[mrapaul]

When I run gradle clean build in the template directory
Then I get the following error

lint-checks/src/main/java/io/bloco/template/lintchecks/MissingExcludePreviewAnnotationDetector.kt:57:33 Unresolved reference: CUSTOM_LINT_CHECKS

> Task :core:data:compileKotlin
w: Opt-in requirement marker kotlin.Experimental is unresolved. Please make sure it's present in the module dependencies
