Jetty 8 Maven Plugin jetty:run-war not detecting WebApplicationInitializer

Question

I'm having problems trying to get a Spring 3.1 Framework webapp using the Servlet 3.0 programmatic way to register the servlet running using the Jetty maven plugin.

Here is my maven plugin definition (specifies an override webdefault.xml that has the default servlet mapping removed):

<plugin>
    <groupId>org.mortbay.jetty</groupId>
    <artifactId>jetty-maven-plugin</artifactId>
    <version>8.1.1.v20120215</version>
    <configuration>
      <systemProperties>
        <systemProperty>
          <name>DEBUG</name>
          <value>TRUE</value>
        </systemProperty>
      </systemProperties>
      <scanIntervalSeconds>0</scanIntervalSeconds>
      <webAppConfig>
        <defaultsDescriptor>src/main/resources/webdefault.xml</defaultsDescriptor>
      </webAppConfig>
      <stopPort>9966</stopPort>
      <stopKey>foo</stopKey>
    </configuration>
  </plugin>

Here's my cut-down webapp:

public class GcpWebApplicationInitializer implements WebApplicationInitializer {
    public void onStartup(ServletContext servletContext) throws ServletException {
        AnnotationConfigWebApplicationContext root = 
          new AnnotationConfigWebApplicationContext();
        root.scan();
        servletContext.addListener(new ContextLoaderListener(root));
        ServletRegistration.Dynamic servlet = servletContext.addServlet("TESTSERVLET", new DispatcherServlet(root));
        servlet.setLoadOnStartup(1);
        servlet.addMapping("/");
    }
}

The commannd line I use to run this up is:

mvn -U clean package jetty:run-war

with the following output (just the run-war part):

As you can see it detected the Spring servlet SpringServletContainerInitializer but that servlet didn't detect the GcpWebApplicationInitializer. BUT if I take the war file and manually put it under a standalone Jetty it will detect the GcpWebApplicationInitializer.

Also if I use mvn -U clean package jetty:run then it will also detect the GcpWebApplicationInitializer as it should.

So why is the jetty:run-war not behaving as I expect? Initially I thought it was the jetty plugin causing the issue but now I think it's more of a Spring issue or classpath issue.

I've tried to debug this in my IDE and it with a breakpoint on the SpringServletContainerInitializer.onStartup() call the jetty:run passes in the correct webAppInitializerClasses set with my servlet class in it. The jetty:run-war on the same breakpoint has no webAppInitializerClasses passed in. It's Jetty that calls this method so it certainly looks like Jetty is not handling the @HandlesTypes(WebApplicationInitializer.class) annotation. — Shane Rowatt, Mar 17 '12 at 04:19
Also in my webdefault.xml I also tried setting metadata-complete to false - which didn't help. I also tried bumping the web_app_2_5.xsd up to web_app_3_0.xsd and still didn't help. — Shane Rowatt, Mar 17 '12 at 04:23

We are using a similar setup with spring 3.1 & jetty 8. Our config is:

        <plugin>
            <groupId>org.mortbay.jetty</groupId>
            <artifactId>jetty-maven-plugin</artifactId>
            <version>${jetty.version}</version>
            <configuration>
                <webApp>
                    <contextPath>/</contextPath>
                </webApp>
                <jettyConfig>src/main/resources/jetty.xml</jettyConfig>
                <systemProperties>
                    <systemProperty>
                        <name>log4j.configuration</name>
                        <value>file://${project.basedir}/src/main/conf/target/generated-resources/log4j.xml</value>

                    <systemProperty>
                        <name>env</name>
                        <value>${env}</value>
                    </systemProperty>
                </systemProperties>
                <stopKey>I_CANT_STAND_IT_ANYMORE</stopKey>
                <stopPort>54124</stopPort>
            </configuration>
        </plugin>

You need maven 3.x, with maven 2 you'll end up with a jetty that is not servlet 3.0 compatible.
