maven custom lifecycle is not recognized - maven-2

Question

I am trying to test a simple custom plugin with custom lifecycle.
Here is my EchoMojo.java file:
package org.sonatype.mavenbook.plugins;
import org.apache.maven.plugin.AbstractMojo;
import org.apache.maven.plugin.MojoExecutionException;
import org.apache.maven.plugin.MojoFailureException;
/**
* Echos an object string to the output screen.
* #goal echo
* #execute lifecycle="custom-echo" phase="package"
*/
public class EchoMojo extends AbstractMojo
{
/**
* Any Object to print out.
* #parameter expression="${echo.message}" default-value="Hello World..."
*/
private Object message;
public void execute()
throws MojoExecutionException, MojoFailureException
{
getLog().info( message.toString() );
}
}
My pom.xml looks like this:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

I added this in my settings.xml:
<pluginGroups>
<pluginGroup>org.sonatype.mavenbook.plugins</pluginGroup>
</pluginGroups>
I created META-INF/maven/lifecycle.xml
<lifecycles>
<lifecycle>
<id>custom-echo</id>
<phases>
<phase>
<id>package</id>
<executions>
<execution>
<goals>
<goal>echo</goal>
</goals>
</execution>
</executions>
</phase>
</phases>
</lifecycle>
</lifecycles>
I have created META-INF/plexus/components.xml
<component-set>
<components>
<component>
<role>org.apache.maven.lifecycle.mapping.LifecycleMapping</role>
<role-hint>custom-echo</role-hint>
<implementation>org.apache.maven.lifecycle.mapping.DefaultLifecycleMapping</implementation>
<configuration>
<phases>
<package>org.sonatype.mavenbook.plugins:echotest-maven-plugin:echo</package>
</phases>
</configuration>
</component>
</components>
</component-set>
When i do mvn echotest:echo, I get "Build Sucessfull".
When i do mvn custom-echo, I get "[ERROR] Unknown lifecycle phase "custom-echo"."
All i wanted is to active my custom plugin when i execute "mvn custom-echo", where custom-echo is a custom lifecycle name
Can someone help me out please.
