Taming the maven versions plugin - configuring rules
I have been a user of the versions maven plugin for many years but I think I never actually used it to its full potential.
Latetly I wanted to control the way updates were resolved when I was invoking
1mvn versions:display-dependency-updates
I wanted to get rid of snapshos and all sorts of different naming convensions libraries use to indicate that this is a work in progress , beta etc.
Fortunately the plugin has a configurable way to define rules that will be evaluated during the execution. These rules support
regex-es so you can easily filter out the noise.
All you have to do is to provide a file that contain these rules.
Example config
1<plugin>
2 <groupId>org.codehaus.mojo</groupId>
3 <artifactId>versions-maven-plugin</artifactId>
4 <version>${mvn.versions.plugin}</version>
5 <configuration>
6 <allowSnapshots>false</allowSnapshots>
7 <rulesUri>file:///${session.executionRootDirectory}/mvn-version-plugin-rules.xml</rulesUri>
8 </configuration>
9</plugin>
The line is a clean maven way - to define where the rule file is. In my case its on the root of the service (next to pom.xml)
1 <rulesUri>file:///${session.executionRootDirectory}/mvn-version-plugin-rules.xml</rulesUri>
The actual rule file:
1<!--This is only used for the maven-versions plugin - is not affecting dependency management resolution-->
2<ruleset xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
3 comparisonMethod="maven"
4 xmlns="http://mojo.codehaus.org/versions-maven-plugin/rule/2.0.0"
5 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">
6 <ignoreVersions>
7 <ignoreVersion type="regex">.*[-_\.](alpha|Alpha|ALPHA|b|beta|Dev|Beta|BETA|rc|RC|M|EA)[-_\.]?[0-9]*</ignoreVersion>
8 </ignoreVersions>
9</ruleset>
Not bad!
