Multi-module Maven project and jetty:run

I'm trying to split a Maven WAR project into two modules, so that I can build a separate JAR file with command line tools. The result has the following structure:

  • pom.xml (packaging pom, has two modules)
  • project-jar/
    • pom.xml (packaging jar)
  • project-war/
    • pom.xml (packaging war, depends on project-jar)

If I run mvn commands from the root, everything works fine. I'd like to keep using mvn jetty:run, but for that I need to execute the command in the WAR subproject. If I do that, fails to find the project-jar subproject, so it won't run. Even mvn jetty:run-war with a completely assembled WAR file in the target directory fails, because it first tries to "build" the project. I've only managed to make it work by installing project-jar into the local Maven repository, which isn't very nice.

Is there a way to use the Jetty plugin in a multi-module Maven configuration?

The documentation for jetty:run notes that

As of Jetty 9.4.7, when using jetty:run in a multi-module build, it is no longer necessary to build each of the modules that form dependencies of the webapp first. Thus, if your webapp depends on other modules in your project and they are present in the reactor at the same time, jetty will use their compiled classes rather than their jar files from your local maven repository.

Thus, add the jetty-maven-plugin to the Maven root project and run mvn jetty:run
