Description

I am using a maven-plugin which manipulates the POM and writes a new POM model.  (similar to 'maven-git-versioning-extension' or 'flatten-maven-plugin').

When writing a POM using the MavenXpp3Writer a property without a value is written out as follows:

 

<project>
  <properties>
    <some.property></some.property>
  </properties>
</project>

 

Would it be possible to write this out with a self-closing tag? Or provide an option to the writer to do so?

 

<project>
  <properties>
    <some.property/>
  </properties>
</project> 

Its just eye-candy but the IDE (IntelliJ) displays warnings for empty tags and I don't want to disable the check globally.

 

Why empty properties?

For some plugins we use empty properties as placeholders which child projects or sub-modules can override.  For example: maven-surefire-plugin `argLine`.  This prevents other IDE errors for missing properties when editing the POM.
