writeMavenPom is not writing in pom

According to https://www.cloudbees.com/blog/new-way-do-continuous-delivery-maven-and-jenkins-pipeline how should writing to a pom with pom.version.replace look like? I assume that pom.version.replace doesn't modify anything but how can the change be saved in pom? I'm currently using this which fails with the update:

   def pom = readMavenPom file: 'pom.xml'
   def version = pom.version.replace("-SNAPSHOT", "")
   writeMavenPom model: pom

I had to add following instruction to save the data: 

pom.version = pom.version.replace("-SNAPSHOT", "")

Although there are better options

I recommend you to use maven versions plugin.

Ypu can remove -SNAPSHOT with this command:

mvn versions:set -DremoveSnapshot

Being inspired from a link I just pasted as a comment to another answer, you could as well have some look into new Maven features for continuous delivery. Namely, you can use properties now (starting with Maven 3.2.1) as a version:

<version>${releaseVersion}</version>
...
<properties>
  <releaseVersion>0-SNAPSHOT</releaseVersion> <!-- sane default -->
</properties>

So you could just pass your desired version during the build as a -Dparameter:

mvn clean package -DreleaseVersion=1.2.3-45

You need to change the pom object. The replace method will not modify the string but return a new one. Since you already stored the changed version you just need to overwrite the pom.version. The object returned by readMavenPom is a Model. This class has a setVersion method which can be used to change the version before writing the object with writeMavenPom to file.

So it should look like this:

def pom = readMavenPom file: 'pom.xml'
def version = pom.version.replace("-SNAPSHOT", "")
pom.version = version
writeMavenPom model: pom
