Description

Working with inner java classes, there are two different issues which I feel belong together.

Consider this java class which I will reference from a groovy script:

package foogroovy;
public class Outer
{
public Outer() {}
public static class Inner
{
public Inner() {}
}
}

Problem #1: making the script compile

The following script does not compile due to a MissingClassException.
It ONLY works when the inner class is referenced and imported as Outer$Inner.

//--------------------------------------------------------------------
import foogroovy.Outer;
// import foogroovy.Outer$Inner;
// this is the only way to make at least case 2 compile

class UseInner1
{
static void main( String[] args )

{ // case 1: Outer.Inner inner = new Outer.Inner(); // case 2: Outer$Inner inner = new Outer$Inner(); // both deliver: groovy.lang.MissingClassException: No such class: Outer in cast for class: UseInner2. At [-1:-1] C:\src\foogroovy\UseInner2.groovy }

}

Problem #2: getting the correct class

Problem #1 can be solved by importing foogroovy.*;. This leads to another issue. Outer.Inner.class seems to be a java.lang.class!!

//--------------------------------------------------------------------
import foogroovy.*;

class UseInner2
{
static void main( String[] args )

{ Outer.Inner inner = new Outer.Inner(); println Outer.Inner.class // gives(!): 'class java.lang.class' println Outer$Inner.class // gives: 'class foogroovy.Outer$Inner' println Outer.class // gives: 'class foogroovy.Outer' }

}
