Status: Resolved
Project: Gradle
Affects Version/s: 1.4
Fix Version/s: None

 Description   

The project (Groovy 2.1.0, gradle 1.4) is attached to this issue.
This annotation:

@Retention(RetentionPolicy.RUNTIME)
@Target([ElementType.TYPE, ElementType.METHOD])
@interface Tx {

    String value() default 'def'
}

on this class:

@Tx
public class PersonServiceJava {
}

results in the following build failure:

:compileGroovy
/home/rafal/Development/IdeaWorkspace/hibertest/src/main/groovy/test/PersonServiceJava.java:4: error: annotation Tx is missing value for the attribute value
@Tx
^
1 error

My environment:

$ ./gradlew --version

I am not sure if this is a Gradle issue, might be something in Groovy, but similar code works in groovyConsole (but the class is not a Java class)... Seems to be something in cross-compilation.

Looks like a Groovy stub generator bug. Here is the Java stub generated by the Groovy compiler (compileGroovy.groovyOptions.keepStubs = true):

import java.lang.annotation.*;
import java.lang.*;
import java.io.*;
import java.net.*;
import java.util.*;
import groovy.lang.*;
import groovy.util.*;

@java.lang.annotation.Retention(value=java.lang.annotation.RetentionPolicy.RUNTIME) @java.lang.annotation.Target(value={java.lang.annotation.ElementType.TYPE,java.lang.annotation.ElementType.METHOD}) public @interface Tx
 {
 java.lang.String value();
}

As you can see, the default value is missing.

Yup, neither does it work on the command line when invoked with groovyc --jointCompilation. Have you issued it to groovy already? If not, I will do it. Thanks.

I haven't.
