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

java intellij-idea groovy gradle build.gradle

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.lang.String errors

java.lang.String errors

or

groovy.lang.Closure errors

groovy.lang.Closure errors

I've tried clearing the file's contents and only writing the top line:

group 'com.me.blah'

but even that results in an error.

For context's sake - this is an individual module in a larger SpringBoot project. This module is a set of simple static files (with Gradle for CSS compilation, static analysis, etc), while the rest are Java modules, and are not having Gradle issues.

Can anyone think why IntelliJ would be struggling to understand this Gradle file?

I've noticed this often. When creating a new project and using the 'Gradle' template, IntelliJ seems to get it all wrong. So what I've resorted to doing is after creating a new project, delete the .idea and .iml files and re-open the project directly from the Gradle file. IntelliJ seems to better understand what is going on in this case.
