Parent POM for Jenkins Plugins

Introduction

This new parent POM is decoupled from the core Jenkins project, both from the Maven and repository perspectives.

The main changes are:

Reduced number of overridable properties. All references (e.g. dependencies and plugin versions) not thought to be overridden are no longer based on properties. The main remaining overridable properties are:
- jenkins.version: The Jenkins version required by the plugin. Mandatory.
- java.level: The Java version to use to build the plugin. Mandatory. Should match the minimum Java version for the selected Jenkins version.
- jenkins-test-harness.version: The JTH version used to test plugin. Uses split test-harness (see JENKINS-32478). If the required Jenkins version is 1.580.1 or higher, JTH 2.1+ is recommended.
- hpi-plugin.version: The HPI Maven Plugin version used by the plugin. (Generally you should not set this to a version lower than that specified in the parent POM.)
- stapler-plugin.version: The Stapler Maven plugin version required by the plugin.
- java.level.test: The Java version to use to build the plugin tests.
- In order to make their versions the same as the used core version, slf4jVersion, node.version and npm.version properties are provided.
Tests are skipped during the perform phase of a release (can be overridden by setting release.skipTests to false).
Javadoc has been set to quiet by default in 2.20+, which means it will only log errors and warnings. If you really want it verbose, set quiet property to false for the plugin.
General clean up.

Being able to specify the jenkins.version simplifies testing the plugin with different core versions, which is important, among others, for the Plugin Compatibility Testing.

Usage

In order to use the new POM:

Change the parent POM of your plugin:

  <parent>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>plugin</artifactId>
    <version>2.29</version> <!-- or whatever the newest version available is -->
    <relativePath />
  </parent>

Override the needed properties, e.g.:

  <properties>
    <jenkins.version>1.609.1</jenkins.version>
    <java.level>7</java.level>
  </properties>

If you had a jar:test-jar execution, delete it and add to properties:

<no-test-jar>false</no-test-jar>

Incrementals

You can configure your plugin to treat every commit as a release candidate. See Incrementals for details.

Baselines

It is handy to be able to select different Jenkins baselines with a Maven profile. To set this up, you must edit your ~/.m2/settings.xml to include some new entries in the <profiles> section. For example:

<profile>
    <id>jenkins-289</id>
    <properties>
        <jenkins.version>2.89.2</jenkins.version>
    </properties>
</profile>
<profile>
    <id>jenkins-273</id>
    <properties>
        <jenkins.version>2.73.3</jenkins.version>
    </properties>
</profile>
<profile>
    <id>jenkins-260</id>
    <properties>
        <jenkins.version>2.60.3</jenkins.version>
    </properties>
</profile>
<profile>
    <id>jenkins-246</id>
    <properties>
        <jenkins.version>2.46.3</jenkins.version>
    </properties>
</profile>
<profile>
    <id>jenkins-232</id>
    <properties>
        <jenkins.version>2.32.3</jenkins.version>
    </properties>
</profile>
<profile>
    <id>jenkins-219</id>
    <properties>
        <jenkins.version>2.19.4</jenkins.version>
    </properties>
</profile>
<profile>
    <id>jenkins-27</id>
    <properties>
        <jenkins.version>2.7.3</jenkins.version>
    </properties>
</profile>
<profile>
    <id>jenkins-651</id>
    <properties>
        <jenkins.version>1.651.3</jenkins.version>
    </properties>
</profile>
<profile>
    <id>jenkins-642</id>
    <properties>
        <jenkins.version>1.642.4</jenkins.version>
    </properties>
</profile>
<profile>
    <id>jenkins-625</id>
    <properties>
        <jenkins.version>1.625.3</jenkins.version>
    </properties>
</profile>
<profile>
    <id>jenkins-609</id>
    <properties>
        <jenkins.version>1.609.3</jenkins.version>
    </properties>
</profile>
<profile>
    <id>jenkins-596</id>
    <properties>
        <jenkins.version>1.596.3</jenkins.version>
    </properties>
</profile>
<profile>
    <id>jenkins-580</id>
    <properties>
        <jenkins.version>1.580.3</jenkins.version>
    </properties>
</profile>
<profile>
    <id>jenkins-565</id>
    <properties>
        <jenkins.version>1.565.3</jenkins.version>
        <jenkins-test-harness.version>1.565.3</jenkins-test-harness.version>
    </properties>
</profile>

Now for example if your plugin normally builds against 1.625.x, but you wish to test compatibility with 1.651.x, there is no need to edit your POM. Just run:

mvn -Pjenkins-651 clean test

mvn -Pjenkins-651 hpi:run

Setup Wizard

By default, the setup wizard (Jenkins >= 2.0) is skipped when using hpi:run. If you want the wizard to be enabled just run:

mvn -Dhudson.Main.development=false hpi:run

For maintainers

You can run

mvn -Prun-plugin-pom-its clean verify

Remember to update the changelog.
