> Given a property of type {{Map<String, Object>}} and the assignment:
> {code}
> myObject.property = ['myKey':"${buildDir}/file-cache"]
> {code}
> I get the following error:
> {quote}
> [Static type checking] - Cannot assign value of type java.util.LinkedHashMap <java.lang.String, groovy.lang.GString> to variable of type java.util.Map <java.lang.String, java.lang.Object>
> {quote}
> I have to manually cast the value to {{Object}} for it to work without warnings:
> {code}
> myObject.property = ['myKey': "${buildDir}/file-cache" as Object]
> {code}
> This should not be needed, since any object is a valid instance of {{Object}}
