Can't get checksum maven plugin to execute automatically

Question

I am using the Maven Checksum Plugin, and I am having problems getting it to execute after the war has been built. Here's my configuration in my superpom under the section:

<build>
    ...
    <pluginManagement>
        <plugins>
            <plugin>
                ...
            </plugin>
            <plugin>
                <groupId>net.ju-n.maven.plugins</groupId>
                <artifactId>checksum-maven-plugin</artifactId>
                <version>1.3-SNAPSHOT</version>
                <executions>
                    <execution>
                        <id>generate-artifact-checksum</id>
                        <phase>package</phase>
                        <goals>
                            <goal>files</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <fileSets>
                        <fileSet>
                            <directory>${project.build.directory}/artifacts</directory>
                        </fileSet>
                    </fileSets>
                </configuration>
            </plugin>
            <plugin>
                ...
            </plugin>
        </plugins>
    </pluginManagement>
</build>

When I run mvn package, the plugin isn't executed. Not there's an error, but just doesn't execute. Nothing is printed out during the build process. The war is processed, the build is declared successful, and the plugin doesn't execute.

I've tried removing the <phase> entities and run mvn verify because according to the documentation on the plugin, the checksum:files goal is automatically bound to the verify phase. Still no execution.

However, the plugin does work if I run:

$ mvn checksum:files

What am I missing in my configuration?

The plugin is not executed because it is declared under the pluginManagement section of your pom.

You should move the configuration of checksum-maven-plugin outside pluginManagement like this:

<build>
    <plugins>
        <plugin>
            ...
        </plugin>
        <plugin>
            <groupId>net.ju-n.maven.plugins</groupId>
            <artifactId>checksum-maven-plugin</artifactId>
            <version>1.3-SNAPSHOT</version>
            <executions>
                <execution>
                    <id>generate-artifact-checksum</id>
                    <phase>package</phase>
                    <goals>
                        <goal>files</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <fileSets>
                    <fileSet>
                        <directory>${project.build.directory}/artifacts</directory>
                    </fileSet>
                </fileSets>
            </configuration>
        </plugin>
        <plugin>
            ...
        </plugin>
    </plugins>
</build>
