Writes a Maven project file. That for example was previously read by readMavenPom.

• model: The Model object to write.
• file: Optional path to a file in the workspace to write to. If left empty the step will write to pom.xml in the current working directory.

Example:

        def pom = readMavenPom file: 'pom.xml'
        //Do some manipulation
        writeMavenPom model: pom
