versions-maven-plugin: How to ignore alpha, beta, release candidate, and milestone versions

Introduction

The versions-maven-plugin, by default, does not ignore versions ending with qualifier strings when searching for the latest version of an artifact.

For example, versions ending with -alpha.14, -beta3, -M-2, and -RC1 will be considered as valid upgrade candidates.

Suppose your project depends on version 3.2.1 of a certain artifact and then 3.3.0-beta is released. The versions-maven-plugin will, by default, consider that to be a valid upgrade.
