Has anyone successfully used Ant4Eclipse (http://www.ant4eclipse.org/) in combination with Project Lombok (http://projectlombok.org/)?

Lombok provides annotations for removing boilerplate code; however, it doesn't appear to play nicely with Ant4Eclipse (headless compilation of Eclipse projects). For instance, the following Lombok sample compiles fine in Eclipse and javac:

import lombok.Getter;
public class LombokTest {
  private @Getter String foo; 
  public LombokTest() {
    String s = this.getFoo();
  }
}

But compiling with Ant4Eclipse's <buildJdtProject> yields the following:

[javac] Compiling 1 source file
[javac] ----------
[javac] 1. WARNING in C:\dev\Java\workspace\LombokTest\src\LombokTest.java (at line 4)
[javac]     private @Getter String foo;
[javac]                            ^^^
[javac] The field LombokTest.foo is never read locally
[javac] ----------
[javac] 2. ERROR in C:\dev\Java\workspace\LombokTest\src\LombokTest.java (at line 8)
[javac]             String s = this.getFoo();
[javac]                             ^^^^^^
[javac] The method getFoo() is undefined for the type LombokTest
[javac] ----------

Has anyone successfully used these libraries together?

Thanks!
