Nils Breunese opened MWRAPPER-134 and commented

I use Renovate to automatically keep dependencies up-to-date and I noticed that the upgrade to Maven Wrapper 3.3.0 removed the wrapperUrl line from {}.mvn/wrapper/maven-wrapper.properties{}. I guess that is related to MWRAPPER-120.

A couple of my colleagues implemented the support for keeping Maven Wrapper up-to-date in Renovate, and I believe Renovate currently determines the version of Maven Wrapper based on the wrapperUrl property, so I think that logic may need to be updated after this change. Without the wrapperUrl property, I think currently the only option to determine the Maven Wrapper version is parsing the mvnw / mvnw.cmd scripts themselves, but that sounds like a clunky and unreliable way.

In a discussion on the maven-users mailinglist, the idea was posted to add a dedicated property for this (e.g. {}wrapperVersion{}), which can be read by external tools.

Affects: 3.3.0
