IntelliJ IDEA and Gradle - Cannot be applied to '(groovy.lang.Closure)'

Question

I have a Gradle file which, whenever I load open it in IntelliJ IDEA 14.1.5, shows IDE errors for the entire file. Namely all the errors seem to be either:

java.

Answer 1

I found this suggestion in the IDEA bug tracker(IDEA-142683):

Workaround:
One can add a comment such as
//noinspection GroovyAssignabilityCheck
to suppress the warning, but this should not be necessary as these are standard every day Gradle usages.

This issue was recently updated and is marked fixed, ready for release with version 2016.2 release.
