使用eclipse创建 dynamic web project

在将项目转换成maven项目时保如下错误

pom文件为eclipse 自动生成没有改动 如下

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">   <modelVersion>4.0.0</modelVersion>   <groupId>test</groupId>   <artifactId>test</artifactId>   <version>0.0.1-SNAPSHOT</version>   <packaging>war</packaging>   <build>     <sourceDirectory>src</sourceDirectory>     <plugins>       <plugin>         <artifactId>maven-compiler-plugin</artifactId>         <version>3.5.1</version>         <configuration>           <source>1.8</source>           <target>1.8</target>         </configuration>       </plugin>       <plugin>         <artifactId>maven-war-plugin</artifactId>         <version>2.6</version>         <configuration>           <warSourceDirectory>WebContent</warSourceDirectory>           <failOnMissingWebXml>false</failOnMissingWebXml>         </configuration>       </plugin>     </plugins>   </build> </project> 

目前已经试过以下方法 都不奏效

1.强行update项目，报错同上

2.删除.m2/repository下的.lastUpdated文件，clean项目之后 再update

3.将插件版本改为低版本2.0

搜索了好多也没有找到答案 ，求高人指点
