maven项目中嵌入的tomcat错误

我想在我使用eclipse的maven项目中使用'tomcat：run'命令来运行我的项目。在这里，我遇到了一些问题：maven项目中嵌入的tomcat错误

这是我的pom.xml的插件代码：

<plugin> 
      <groupId>org.codehaus.mojo</groupId> 
      <artifactId>tomcat-maven-plugin</artifactId> 
      <version>1.1</version> 
      <configuration> 
       <source>${java.version}</source> 
       <target>${java.version}</target> 
       <port>9999</port> 
        <path>/webapp</path> 
        <warFile>${project.basedir}/target/${project.build.finalName}.war</warFile> 

      </configuration> 
     </plugin>

这里是完整的错误堆栈跟踪

java.lang.LinkageError: loader constraint violation: when resolving interface method "javax.servlet.jsp.JspApplicationContext.getExpressionFactory()Ljavax/el/ExpressionFactory;" the class loader (instance of org/apache/jasper/servlet/JasperLoader) of the current class, org/apache/jsp/index_jsp, and the class loader (instance of org/codehaus/plexus/classworlds/realm/ClassRealm) for the method's defining class, javax/servlet/jsp/JspApplicationContext, have different Class objects for the type javax/el/ExpressionFactory used in the signature

我怎样才能解决这个问题呢？

任何建议将理解

您有两种选择添加到您的项目库，例如jsp-api.jar，el-api.jar，servlet-api.jar等：将这些库添加为Java Build Path中的外部jar; 添加它们作为行家依存关系，设定为每个所提供的范围，例如： javax.servlet.jsp 的jsp-API 2.1 提供 –

您需要包括servlet的依赖关系@Ashwin说。

这样的：

<dependencies> 
    <dependency> 
     <groupId>javax.servlet</groupId> 
     <artifactId>javax.servlet-api</artifactId> 
     <version>3.0.1</version> 
     <scope>provided</scope> 
    </dependency> 
    <dependency> 
     <groupId>javax.servlet</groupId> 
     <artifactId>jstl</artifactId> 
     <version>1.2</version> 
    </dependency> 
</dependencies>

我把这个例子从这个blog post配置。 servlet api和jstl的版本可能会根据tomcat版本而变化。
