Maven Shade Plugin: only creates SNAPSHOT, not release - maven

Question

We are using Apache Flink, which according to its documentation needs the Maven Shade Plugin to build an application JAR that contains all dependencies.
I am used to using the Maven Release Plugin, it appears that the Shade plugin does a similar job, except bundling and renaming (aka "shading") dependencies.
We have a Jenkins pipeline job that makes the following call on the "master" branch:
mvn -B -Dmaven.test.failure.ignore=true -Dmaven.test.skip=true -DskipTests release:prepare release:perform -e
What I would expect from this is the following (probably not in this order):
a new SNAPSHOT version is built and uploaded to Nexus
a new RELEASE version is built and uploaded to Nexus
the branch is tagged with the app name & release number
the POM is updated with a new SNAPSHOT number
the POM is checked in to Git
What actually happens:
a "local" branch is created & tagged (that is, local to the Jenkins instance)
a new SNAPSHOT version is built and uploaded to Nexus

UPDATE:
The solution was to use explicit version the Maven Release Plugin (2.4.2) in pom
