Description

This error at https://ci-builds.apache.org/job/Sling/view/Monitor/job/modules/job/sling-maven-launchpad-plugin/job/master/56/console seems to be common to many of our modules, for which mvn sonar:sonar fails on Jenkins:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.8:run
(set-bundle-required-execution-environment) on project maven-launchpad-plugin:
An Ant BuildException has occured:
Unable to create javax script engine for javascript
[ERROR] around Ant part ...
<script language="javascript">var System = java.lang.System;... @ 4:33
in /home/jenkins/workspace/ng-maven-launchpad-plugin_master/target/antrun/build-main.xml
...
Marking build unstable due to mvn sonar:sonar failing. See https://cwiki.apache.org/confluence/display/SLING/SonarCloud+analysis for more info.

Running mvn help:effective-pom on the {{}} module which is also failing shows the below code which is apparently the culprit.

        <execution>
            <id>set-bundle-required-execution-environment</id>
...
              <target>
                <script language="javascript">var System = java.lang.System;
                                    var bree = "JavaSE-1.6";
 ...

This looks related to MANTRUN-200 and those builds have been failing for a while, https://ci-builds.apache.org/job/Sling/view/Monitor/job/modules/job/sling-org-apache-sling-jcr-jcr-wrapper/job/master/47/ from June 8 for example has the same problem.
