--------------------------------------
Summary: Provide a reliable way to determine the Maven Wrapper
version
Key: MWRAPPER-134
URL: https://issues.apache.org/jira/browse/MWRAPPER-134
Project: Maven Wrapper
Issue Type: Improvement
Affects Versions: 3.3.0
Reporter: Nils Breunese
I use [Renovate|https://github.com/renovatebot/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.bat` 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.
