Description

A MultipleCompilationErrorsException is thrown when we try to load a class that has a reference to a nested class via annotation.

Here a small example:
We have two classes class A and B. Class A has a reference to the nested class of class B (NestedInB) in the annotation. Class A can not be loaded except the annotation is removed.
 

package pkg2
import pkg1.B

class A { 
@SuppressWarnings(value = [B.NestedInB.NestedProp])  
  A() {   
   String name = B.NestedInB.class.getName();      
   System.out.println(name);           
   System.out.println(B.NestedInB.NestedProp);  
  }
} 

package pkg1
import pkg2.A

public class B {
      public static final String Prop = "ABCD";

     B() {
        A a = new A()
      }
  
     public static class NestedInB {
        public static final String NestedProp = "ABCD";
   }
}

@Test
public void test2() throws Exception {
    final File mainDirectory = new File("Path to the class A and B");
    URL url = mainDirectory.getAbsoluteFile().toURI().toURL();
    groovyClassLoader.addURL(url);
    groovyClassLoader.addClasspath(mainDirectory.getPath());
    final Class<?> a = groovyClassLoader.loadClass("pkg2.A");
    a.newInstance();
    assertNotNull(a);
}
