Could not find goal in custom maven plugin

I am trying to develop a custom Maven plugin, i am following the tutorial from the official maven documentation as described here:

http://maven.apache.org/guides/plugin/guide-java-plugin-development.html

However, when i try to use my plugin from a different project i get the following:

Could not find goal 'generateProtoClasses' in plugin com.myComapny.maven.plugin:myCompany-protobuf-plugin:1.0 among available goals -> [Help 1]

This is my MOJO:

@Mojo(name = "generateProtoClasses", defaultPhase = LifecyclePhase.GENERATE_RESOURCES)
public class CompileProtoClasses extends AbstractMojo {


    @Parameter(defaultValue = "mokmok")
    private String inputPath;

    public void execute() throws MojoExecutionException {
        getLog().info("@@@@@@@@@@@@@@@@@@@@@@@");
        getLog().info(inputPath);
    }

}

This is the snippet on the pom.xml file of the project using the plugin:

<plugin>
        <groupId>com.myCompany.maven.plugin</groupId>
        <artifactId>legolas-protobuf-plugin</artifactId>
        <version>1.0</version>
        <configuration>
          <inputPath>yoyo</inputPath>
        </configuration>
        <executions>
            <execution>
                <goals>
                    <goal>generateProtoClasses</goal>
                </goals>
            </execution>
        </executions>
    </plugin>

Pom of the plugin project:

Does it work if you use the old-style xdoclet annotations?

/**
 * @goal generateProtoClasses
 * @phase generate-resources
 */
public class CompileProtoClasses extends AbstractMojo {

    /**
     * @parameter default-value="mokmok"
     */
    private String inputPath;

    public void execute() throws MojoExecutionException {
        getLog().info("@@@@@@@@@@@@@@@@@@@@@@@");
        getLog().info(inputPath);
    }
}

I am getting this error with maven 3.0.5 (Netbeans Build-In) Get the latest maven version and build the maven-plugin again.

add the following to your build->maven-plugin-plugin

<execution>
  <id>mojo-descriptor</id>
  <goals>
    <goal>descriptor</goal>
  </goals>
</execution>
