Groovy compiling despite error in function arguments

Question

Is this legal in Groovy?

class RequestContext {
    def static requestContext

    def static setRequestContext(rc) {
        requestContext = rc
    }
}

Given the above I expect the following to fail at compile time using the groovy-eclipse-compiler:

RequestContext.setRequestContext()

Yet this passes and I'm trying to get this to fail at mvn compile time.

It can't fail at compile time, because you might add that method dynamically at runtime via the metaclass, ie:

class Test {
}

Test.metaClass.static.woo = { -> println "yay" }

Test.woo() // prints 'yay'

To fail at compile time, you'd need to annotate the calling class with @CompileStatic or @TypeChecked
