Build problem with Maven

Question

Hi.
I have upgraded from 1.5 APT to the 1.6 method of doing compile time annotations, and I am runing into a problem trying to build a jar containing my annotations processor.
I get the error from maven (mvn package)
[INFO] Compilation failure
error: Bad service configuration file, or exception thrown while constructing Processor object: javax.annotation.processing.Processor: Provider annotations.processing.processors.CodeAnnotationProcessor not found
I have the following directory structure
src
--main
----java
------annotations
--------processing
----------processors
------------CodeAnnotationProcessor.java
----------annotations
------------CodeAnnotation.java
----resources
------META-INF
--------service
----------javax.annotation.processing.Processor
I build this with the following with maven
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

                    <target>1.6</target>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>The javax.annotation.processing.Processor file contains
annotations.processing.processors.CodeAnnotationProcessorAny my
package annotations.processing.processors;
import javax.annotation.processing.AbstractProcessor;
import javax.annotation.processing.RoundEnvironment;
import javax.annotation.processing.SupportedSourceVersion;
import javax.annotation.processing.SupportedAnnotationTypes;
import javax.lang.model.element.TypeElement;
import javax.lang.model.SourceVersion;
import java.util.Set;
@SupportedAnnotationTypes(
        "annotations.processing.annotations.CodeAnnotation")
@SupportedSourceVersion(SourceVersion.RELEASE_6)
public class CodeAnnotationProcessor extends AbstractProcessor {
    public boolean process(Set<? extends TypeElement> annotations,
                           RoundEnvironment roundEnv) {
        return true;
}And my CodeAnnotation is as follows
package annotations.processing.annotations;
import java.lang.annotation.Target;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
@Target(ElementType.TYPE)
@Retention(RetentionPolicy.SOURCE)
public @interface CodeAnnotation {
}

error: Bad service configuration file, or exception thrown while constructing Processor object: javax.annotation.processing.Processor: Provider annotations.processing.processors.CodeAnnotationProcessor not foundFor me it worked when I used the settings
<plugins>
  <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <configuration>
        <source>1.6</source>
        <target>1.6</target>
        <fork>true</fork>
        <executable>${java.home}/../bin/javac</executable>
        <compilerArgument>-proc:none</compilerArgument>
      </configuration>
    </plugin>
</plugins>
...Forking the compiler is perhaps not the best option, but its just for the annotation processor.
