Maven versions auto-update

Using the maven versions plugin

Updating dependencies versions

Update parent

http://www.mojohaus.org/versions-maven-plugin/update-parent-mojo.html

./mvnw versions:update-parent

Problem: provides updates to alpha, beta, milestone, …​ and other non final versions. To avoid it, add following configuration:

pom.xml

      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>versions-maven-plugin</artifactId>
        <configuration>
          <rulesUri>file:///${project.basedir}/maven-version-rules.xml</rulesUri>
        </configuration>
      </plugin>

maven-version-rules.xml

<ruleset comparisonMethod="maven"
  xmlns="https://mojo.codehaus.org/versions-maven-plugin/rule/2.0.0"
  xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="https://mojo.codehaus.org/versions-maven-plugin/rule/2.0.0 https://mojo.codehaus.org/versions-maven-plugin/xsd/rule-2.0.0.xsd">
  <ignoreVersions>
    <ignoreVersion type="regex">.*[-_\.](alpha|Alpha|ALPHA|b|beta|Beta|BETA|rc|RC|M|EA)[-_\.]?[0-9]*</ignoreVersion>
  </ignoreVersions>
</ruleset>

Update dependencies

Two options depending on how you define versions:

• In each dependency: use the versions:use-* plugin goals.

• In properties: use the versions:update-properties goal.

Don’t mix them and use the version:use-* plugins, it will replace any properties used in versions by the versions itself.

We are going to cover the properties based version update.

./mvnw versions:update-properties

All at once

./mvnw versions:update-parent versions:update-properties

Excludes

In case there is a problem or you don’t want to migrate some dependencies:

See https://www.mojohaus.org/versions-maven-plugin/examples/update-properties.html

pom.xml

          <excludes>
            <exclude>org.webjars:*</exclude>
          </excludes>
