Maven “versions” plugin – how to exclude alpha/beta versions from response?

You can configure the versions plugin like this:

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>versions-maven-plugin</artifactId>
    <version>2.1</version>
    <configuration>
        <rulesUri>someUrl</rulesUri>
    </configuration>
</plugin>

someUrl can also be a file URL. The syntax of the rules file is given in http://www.mojohaus.org/versions-maven-plugin/version-rules.html, it may contain something like this:

<ruleset comparisonMethod="maven"
  xmlns="http://mojo.codehaus.org/versions-maven-plugin/rule/2.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://mojo.codehaus.org/versions-maven-plugin/rule/2.0.0 http://mojo.codehaus.org/versions-maven-plugin/xsd/rule-2.0.0.xsd">
  <ignoreVersions>
    <ignoreVersion type="regex">.*-beta.</ignoreVersion>
    <ignoreVersion type="regex">.*_ALPHA</ignoreVersion>
  </ignoreVersions>
</ruleset>
