Description

On annotation attributes, when assigning a constant with a "." in its name (as is the case when the constant is defined in a different class than the one being compiled), groovy generates org.codehaus.groovy.ast.expr.PropertyExpression.

See simple test case below.

— Tag.java

package pkg;

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


@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD,ElementType.FIELD})
public @interface Tag {
        String value() default "";
}

— TagType.java

package pkg;

import org.apache.log4j.Logger;

public class TagType {
        private final static Logger theLogger = Logger.getLogger(TagType.class);
        public static final String TAG_1 = "tag_1";
        public static final String TAG_2 = "tag_2";
}

— GroovyClassWithAnnotationsAndConstants.groovy

package pkg;

import pkg.Tag;
import pkg.TagType

class GroovyClassWithAnnotationsAndConstants {

        int myIntField;

        @Tag( value = TagType.TAG_1) // this will not compile and generate org.codehaus.groovy.ast.expr.PropertyExpression
        //@Tag( value = "tag_1") //the commented version, which uses a string literal does compile
        public int getIntField() {
                return myIntField;
        }

        public void setIntField(int value) {
                myIntField = value;
        }
}
