And what about to use this maven lib:

<dependency>
            <groupId>org.apache.maven</groupId>
            <artifactId>maven-model</artifactId>
            <scope>test</scope>
        </dependency>

And then parser / change the pom with something like

File pom = getFileFromApplication(app, ROOT_FOLDER, "pom.xml");
            MavenXpp3Reader reader = new MavenXpp3Reader();
            Model model = reader.read(new FileReader(pom));
            model.setPackaging("pom");

            MavenXpp3Writer mavenWriter = new MavenXpp3Writer();
            Writer writer = new FileWriter(pom.getPath());
            mavenWriter.write(writer, model);

We do not need such advanced modifications. Read+replace is enough
