Accessing Test Classes
 
  In case your pre-/post-build scripts perform complex operations that you would rather like to refactor out into some
  utility class instead of copy&pasting them in each script, you can use the parameter <<<addTestClassPath>>>:

+----
<project>
  <build>
    <plugins>
      <plugin>
        <artifactId>maven-invoker-plugin</artifactId>
        <version>${project.version}</version>
        <configuration>
          <addTestClassPath>true</addTestClassPath>
        </configuration>
        <executions>
          <execution>
            <id>integration-test</id>
            <goals>
              <goal>run</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
</project>
+----

  Setting <<<addTestClassPath>>> to <<<true>>> will prepend the directories <<<$\{project.build.testOutputDirectory\}>>>,
  <<<$\{project.build.outputDirectory\}>>> and all dependencies of your project to the class path of the script
  interpreter. Among others, this allows you to create some utility classes in your test source tree and use this code
  for the hook scripts.
  
  <Note:> Of course, this requires your test classes to be compiled before running the integration tests but this is
  usually the case if you employ the Invoker Plugin during the lifecycle phase <<<integration-test>>>.
