How to make jetty-maven-plugin deploy a war that is retrieved from a repository?

I'm setting up an integration test module for a good sized web project. The integration test module is separated from the web project itself, and it has it's own pom.

The idea is to use the maven-soapui-plugin to send requests and verify the response. Setting up the soapui-plugin is no hassle. However, I'm having trouble with figuring out how I can tell the jetty-maven-plugin to deploy a war from a remote repository.

If I have understood correctly, the jetty-maven-plugin has a property called '<webApp>/<webApp>' which lets me specify the war file to deploy. The problem is that the war file is not present in the module itself.

I have heard that I can use the maven assembly plugin to retrieve the war from a repository via the projects artifactId, but I am yet to figure out how I would go about doing so.

Here's a summary of what I want:

1. Retrieve a specific war from a repository or the like, in example via its artifactId.
2. Deploy this war to the jetty-maven-plugin (goal deploy-war?)
3. get maven-soapui-plugin to run tests and report the results back in the integration-test phase.

I am pretty sure I've got step 3 covered, but I am very unsure how to achieve step 1 and 2.

Any help is greatly appreciated

It is maybe possible to use dependency:copy to retrieve the war, unpack it and to get the whole thing working with the maven jetty plugin, but this would be hacky and kinda ugly. A cleaner solution would be to use the Maven Cargo plugin and this is my suggestion. Below, a sample POM showing how to retrieve a WAR artifact using its coordinates and how to deploy it on an embedded Jetty container using Cargo:

<dependencies>
  <dependency>
    <groupId>war group id</groupId>
    <artifactId>war artifact id</artifactId>
    <type>war</type>
    <version>war version</version>
  </dependency>
  ...
</dependencies>
...
<build>
  <plugins>
    <plugin>
      <groupId>org.codehaus.cargo</groupId>
      <artifactId>cargo-maven2-plugin</artifactId>
      <configuration>
        <!-- Container configuration -->
        <container>
          <containerId>jetty6x</containerId>
          <type>embedded</type>
        </container>
        <!-- Configuration to use with the container or the deployer -->
        <configuration>
          <deployables>
            <deployable>
              <groupId>war group id</groupId>
              <artifactId>war artifact id</artifactId>
              <type>war</type>
              <properties>
                <context>war context</context>
              </properties>
            </deployable>
          </deployables>
        </configuration>
        <!-- Don't wait, execute the tests after the container is started -->
        <wait>false</wait>
      </configuration>
      <executions>
        <execution>
          <id>start-container</id>
          <phase>pre-integration-test</phase>
          <goals>
            <goal>start</goal>
          </goals>
        </execution>
        <execution>
          <id>stop-container</id>
          <phase>post-integration-test</phase>
          <goals>
            <goal>stop</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
    ...
  </plugins>
  ...
</build>

Finally, just bind the soapui plugin on the integration-test phase.
