maven jar plugin cannot be resolved

Question

I am trying to learn hyperjaxb3, so I downloaded the zip file containing the maven project for the purchase order tutorial for hibernate and maven from this link, and then imported it into eclipse as a new maven project. But I am getting the following error message in the pom.xml:

Plugin execution not covered by lifecycle configuration:  
org.jvnet.hyperjaxb3:maven-hyperjaxb3-plugin:0.5.6:generate (execution: default, phase: generate-sources)

I tried to resolve this error message by adding the following dependency to the pom.xml, which I found at this link:

<dependency>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>2.3.2</version>
</dependency>

But I am still getting the same error. There is no stack trace because I have not tried to compile the program. It is a compile error message that eclipse gives in the pom.

How can I resolve this error?

The complete pom.xml can be viewed by clicking on this link.

Plugins with executions goals need to be moved to <pluginManagement> to get rid of this error. It should look like this:

<build>
    <plugins>
        <!-- plugins  --> 
    </plugins>
    <pluginManagement>
        <plugins>
            <!-- plugins with execution goals --> 
        </plugins>
    </pluginManagement>
</build>
