Can't seem to get Lombok to work in unit tests

Question

We've been putting together some (really simple) code in order to test out and introduce Lombok annotations into our project to make our code a bit nicer. Unfortunately, seems to break in testing, both through Maven and when the tests are run through IntelliJ.

Our domain classes look something like:

package foo.bar;

import lombok.Data;

@Data
public class Noddy {

    private int id;
    private String name;

}

With a corresponding test:

package foo.bar;

import org.junit.Test;
import static org.junit.Assert.assertEquals;

public class NoddyTest {

    @Test
    public void testLombokAnnotations(){
        Noddy noddy = new Noddy();
        noddy.setId(1);
        noddy.setName("some name");
        assertEquals(noddy.getName(), "some name");
    }
}

We have the aspectjrt dependency in Maven (as well as the relevant plugin in IntelliJ), and the aspectj-maven-plugin.

We're running with Maven 2-style POMs, JSDK 1.6.0_31, Lombok 0.11.0:

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>0.11.0</version>
</dependency>

Are we doing something stupid or missing something obvious?

It would be great if we can get this working, as I've had an eye to using Lombok in production for some time now.

Many thanks,

P.

(FWIW, IntelliJ 11.1.2 has the Lombok plugin 0.4 and seems to be using ACJ for this project)

The problem seems to be that the lombok generated code is overwritten by ajc, and according to a blog entry I found by Fabrizio Giudici, there is no "clean" Maven solution due to a bug in the Maven AspectJ plugin that prevents you from passing the necessary arguments to ajc.

He proposes a workaround here: http://weblogs.java.net/blog/fabriziogiudici/archive/2011/07/19/making-lombok-aspectj-and-maven-co-exist

Actually, this worked for me, and it's arguably a cleaner solution. You might have to add an execution phase for the test classes with an additional weave directory.
