Configure Perforce scm in a maven project to get the latest list of changes

Question

I am migrating the project to Maven, and since we are used to always referring to our assemblies by the latest change number in our Perforce SCM repository, I would like to be able to extract this information

I am trying to configure the Maven scm plugin through the following resources:

• http://maven.apache.org/scm/maven-scm-plugin/usage.html for general use
• http://www.perforce.com/perforce/doc.current/manuals/p4maven/index.html

At first I don’t understand how to make it work, so if anyone has a fully working example, I will be glad, on my side I tried to add to my pom:

<scm>
    <connection>
        scm:perforce:localhost:1666://depot/
        <my_project>
            /
            <version>
    </connection>
    <developerConnection>
        scm:perforce:localhost:1666:/depot/
        <my_project>
            /
            <version>
    </developerConnection>
    <url>http://somerepository.com/view.cvs</url>
</scm>
...
<plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-scm-plugin</artifactId>
        <version>1.6</version>
        <dependencies>
            <!-- P4Maven -->
            <dependency>
                <groupId>com.perforce</groupId>
                <artifactId>p4maven</artifactId>
                <version>[2011,2012)</version>
            </dependency>
        </dependencies>
        <configuration>
            <connectionType>//depot/proto/kernel/kernel/04.00/maven2</connectionType>
            <username>my local username</username>
            <password>xxxxxx</password>
            <includes>**</includes>
        </configuration>
    </plugin>
</plugins>

this leads me to:

Maven.

Answer 4

I landed here looking for a solution to the similar "NO Configuration can be defined" problem I encountered with the Code Collaborator client with P4. I ended up uninstalling the P4 client and reinstalling it to make it work.
