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

Happened to me recently on windows. I tried all of the above but it didn't work.

What i did:

1 - I had JAVA_HOME environment variable already set. So IDEA picked that as project SDK and these warnings showed up.

2 - So, i removed the default JAVA_HOME from project SDK and manually added jdk path. Restarted and all warnings were gone.

Maybe it will help someone. Thanks.
