underflow中的编译错误

Question

我正在使用underflow开发一个web应用程序，对java还很陌生。我在运行ServeletEngine.java时遇到了一个错误。我查看了其他相关的帖子，但它们还没有解决我的查询。请帮帮我。

错误：[Error]无法执行目标org.apache.maven.plugins:maven编译器插件：2.3.2:在项目下的服务器上编译（默认编译）：编译失败：编译失败。

我的目录结构是：~/bundertow-server/src/main/java.com/mastertheoss/bundertow/ServeletEngine.java

我的pom.xml文件是：$cat~/bunderstream服务器/pom.xml

ServeletEngine.java位于：$cat~/bundertow-server/src/main/java.com/mastertheoss/bundertow/ServerEngine.java包com.masterthebox.undertow；导入io.undertow.undertow；导入io.bunderstream.server.*；导入io.undertow.util.Headers；

public class ServletEngine {

    public static final String MYAPP = "/myapp";
    public static void main(final String[] args)  {
            try {
                DeploymentInfo servletBuilder = deployment()
                        .setClassLoader(ServletEngine.class.getClassLoader())
                        .setContextPath(MYAPP)
                        .setDeploymentName("test.war")
                        .addListener(new ListenerInfo(MySessionListener.class))
                        .addServlets(
                                servlet("App", App.class)
                                        .addInitParam("message", "Hello World Implementing Servelets")    
                                        .addMapping("/myservlet"));
                DeploymentManager manager = defaultContainer().addDeployment(servletBuilder);
                manager.deploy();
                HttpHandler servletHandler = manager.start();
                PathHandler path = Handlers.path(Handlers.redirect(MYAPP))
                        .addPrefixPath(MYAPP, servletHandler);
                Undertow server = Undertow.builder()
                        .addHttpListener(8080, "localhost")
                        .setHandler(path)
                        .build();
                server.start();
            }  catch (ServletException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
    }
}

如果你需要更多信息，请告诉我。

Answer 1

似乎在pom.xml上，类名不正确：

<mainClass>com.mastertheboss.undertow.ServeletEngine</mainClass>

应该是：

<mainClass>com.mastertheboss.undertow.ServletEngine</mainClass>

我说得对吗？

问候！
