Some projects in the java maven world make use of the maven wrapper: https://github.com/takari/maven-wrapper

which lets a developer set the version of maven and have the build more consistently.

Updating the version requires automatic updating of the folder .mvn/wrapper/maven-wrapper.properties

e.g. distributionUrl=https://repo1.maven.org/maven2/org/apache/maven/apache-maven/3.5.2/apache-maven-3.5.2-bin.zip -> distributionUrl=https://repo1.maven.org/maven2/org/apache/maven/apache-maven/3.5.3/apache-maven-3.5.3-bin.zip

See: https://maven.apache.org/docs/history.html

Would be cool to have these being auto bumped.
