Description

First, create the following annotation in Java:

 
package problem;

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface Test
{
    String name() default "";
}

Second, create the following groovy script:

 
import problem.Test;
class Script
{
    @Test(name="problems")
    void teste()
    {
    }
}

Finally, try to find the annotated method in Java:

        GroovyClassLoader loader = new GroovyClassLoader(TesteMain.class.getClassLoader());
        Class clazz = loader.parseClass(new File("c:\\Script.groovy"));
        
        System.out.println(clazz.getCanonicalName());
        for (Method m : clazz.getMethods())
        {
            for (Annotation a : m.getDeclaredAnnotations())
                System.out.println(a.toString());
        }

The output will only show the class name, not the annotated method. Using a java class instead of a Groovy script, everything works fine.
