    Description

      To reproduce, create a Maven module with:

      <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

      <artifactId>xwiki-platform-test</artifactId>
      <version>${project.version}</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
  <build>
    <testSourceDirectory>src/test/it</testSourceDirectory>
    <plugins>
      <!-- Even though the functional-test packaging ensures that the packager plugin will execute we still need to
           redefine it here in order to make sure the right version is used as otherwise Maven will use the last
           released version which may be the wrong one. -->
      <plugin>
        <groupId>org.xwiki.platform</groupId>
        <artifactId>xwiki-platform-tool-packager-plugin</artifactId>
        <version>${project.version}</version>
      </plugin>
    </plugins>
    <extensions>
      <!-- Needed to add support for the "functional-test" packaging -->
      <extension>
        <groupId>org.xwiki.platform</groupId>
        <artifactId>xwiki-platform-tool-functional-test-lifecycle</artifactId>
        <version>${project.version}</version>
      </extension>
    </extensions>
  </build>
</project>

      Then run "mvn install".
      Then go in target/xwiki/ and start XWiki from there: "sh start_xwiki.sh"
      Login as superadmin, create a page and try to export it

      It'll give:
