java - 运行 Maven 项目的警告 (Spring MVC)

Question

当我运行目标为 jetty:run for Spring MVC 的 Maven 项目时，我收到以下警告:

[WARNING] Failed startup of context org.mortbay.jetty.plugin.Jetty6PluginWebAppContext@7dd712e8{/dfaMusicStore,C:\Users\Tony Do\Desktop\Eclipse\WORKSPACE\PROJECTS\dfaMusicStore\src\main\webapp}

我在“Maven MVC”库中包含了以下 JAR 文件:

jetty-6.1.26.jar, 
jetty-plus-6.1.26.jar, 
maven-hudson-plugin-6.1.7.jar, 
org.mortbay.jetty.util.jar, 
plexus-classworlds-2.5.1.jar

“Spring MVC”库中的以下 JAR 文件:

classmate-1.0.0.jar, 
hibernate-validator-5.1.3.Final.jar, 
jboss-logging-3.1.3.GA.jar, 
validation-api-1.1.0.Final.jar, 
commons-logging-1.2.jar, 

All .jar files in spring-framework-4.1.4.RELEASE/libs/ folder 
(spring-context-4.1.4.RELEASE.jar, spring-web-4.1.4.RELEASE.jar, ...)

如何修复这些警告以运行 Spring MVC 的 Maven 项目？非常感谢。

除了上面的依赖之外，使用这个插件作为 jetty ，在你让它开始工作之前先省略配置

   <plugin>
            <groupId>org.eclipse.jetty</groupId>
            <artifactId>jetty-maven-plugin</artifactId>
            <version>9.1.1.v20140108</version>
        </plugin>
