Description

I attached a sample project. The offending class is shown below. For some reason passing the closure inline triggers the error. The error goes away if I remove @CompileStatic, or declare the closure variable before passing it into method2. It also does not occur when compiling in IDEA, only with Ant.

The error itself is easy to work around, but very difficult to identify since there is nothing in the error indicating what code triggered it.

@groovy.transform.CompileStatic
class MyClass {
    void method1() {
        method2({})
    }

    void method2(@DelegatesTo(strategy = Closure.DELEGATE_FIRST, value = String) Closure body) {

    }
}
