我正在尝试使用嵌入式Undertow服务器构建一个简单的JSF Web应用程序。

项目的Gradle依赖关系：

dependencies {

               compile group: 'io.undertow', name: 'undertow-core',    version: '1.4.0.CR3'
               compile group: 'io.undertow', name: 'undertow-servlet', version: '1.4.0.CR3'
               compile group: 'javax', name: 'javaee-api', version: '7.0'
               compile group: 'org.glassfish', name: 'javax.faces', version: '2.2.11'

}

示例Undertow服务器代码：

public class HelloWorldServer {

    public static void main(final String[] args) throws ServletException {

        DeploymentInfo servletContainer=Servlets.deployment()
                .setClassLoader(HelloWorldServer.class.getClassLoader())
                .setDeploymentName("helloWorld.war")
                .setContextPath("")
                .addServlet(Servlets.servlet("javax.faces.webapp.FacesServlet",FacesServlet.class)
                .addMappings("/faces/*","/javax.faces.resource/*")
                .setLoadOnStartup(1));
        DeploymentManager manager=Servlets.defaultContainer().addDeployment(servletContainer);
        manager.deploy();
        HttpHandler servletHandler=manager.start();
        PathHandler path = Handlers.path(Handlers.redirect(""))
                    .addPrefixPath("/", servletHandler);

         Undertow server = Undertow.builder()
                    .addHttpListener(8080, "localhost")
                    .setHandler(path)
                    .build();
            server.start();

    }
}

当我启动服务器时，出现以下错误：
