maven mojo for unzip folders?

Question

How to write java program (mojo) to unzip folders in specific location? I'm new to maven if anyone help me highly appreciate.

/**
    * The Zip archiver.
    * @parameter \
    expression="${component.org.codehaus.plexus.archiver.Archiver#zip}"
    */

    private ZipArchiver zipArchiver;

    /**
    * Directory containing the build files.
    * @parameter expression="${project.build.directory}/Test"
    */

    private File buildDirectory;

    /**
    * Base directory of the project.
    * @parameter expression="${basedir}"
    */

    private File baseDirectory;

You can either use the maven-dependency-plugin like this:

<project>
   [...]
   <build>
     <plugins>
       <plugin>
         <groupId>org.apache.maven.plugins</groupId>
         <artifactId>maven-dependency-plugin</artifactId>
         <version>2.6</version>
         <executions>
           <execution>
             <id>unpack</id>
             <phase>package</phase>
             <goals>
               <goal>unpack</goal>
             </goals>
             <configuration>
               <artifactItems>
                 <artifactItem>
                   <groupId>junit</groupId>
                   <artifactId>junit</artifactId>
                   <version>3.8.1</version>
                   <type>jar</type>
                   <overWrite>false</overWrite>
                   <outputDirectory>${project.build.directory}/alternateLocation</outputDirectory>

                 </artifactItem>
               </artifactItems>
                ...
               <overWriteReleases>false</overWriteReleases>
               <overWriteSnapshots>true</overWriteSnapshots>
             </configuration>
           </execution>
         </executions>
       </plugin>
     </plugins>
   </build>
   [...]
 </project>

Or you can use the truezip-maven-plugin like the following:

  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>truezip-maven-plugin</artifactId>
    <version>1.1</version>
    <executions>
      <execution>
        <id>unpack</id>
        <goals>
          <goal>cp</goal>
        </goals>
        <phase>ThePhaseYouLike</phase>
        <configuration>
          <from>${project.build.directory}/WhatEveryArchive.zip</from>
          <to>${project.build.directory}</to>
        </configuration>
      </execution>
    </executions>
  </plugin>
