ref PR: https://github.com/apache/maven-archetype/pull/128
> PomUtils.addNewModule Pretty-Printing has issue on java 9+
> ----------------------------------------------------------
>
> Key: ARCHETYPE-637
> URL: https://issues.apache.org/jira/browse/ARCHETYPE-637
> Project: Maven Archetype
> Issue Type: Bug
> Components: Generator
> Reporter: qxo
> Priority: Minor
>
>
> *As of Java 9, the _Transformer_ class's pretty-print feature doesn't define
> the actual format. Therefore, whitespace-only nodes will be outputted as
> well.* This has been discussed in this [JDK bug
> ticket|https://bugs.openjdk.java.net/browse/JDK-8262285?attachmentViewMode=list].
> Also, [Java 9's release
> note|https://www.oracle.com/java/technologies/javase/9-notes.html] has
> explained this in the xml/jaxp section.
> *If we want our pretty-print method to always generate the same format under
> various Java versions, we need to provide a stylesheet file.*
