java-web - 使用eclipse创建javaweb 项目 maven报错

Question

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

자신의 nexus(192.168.15.1:8080/nexus) maven 라이브러리 에이전트가 제대로 작동하는지 확인하고 nexus에 필요한 플러그인이 있는지 확인하세요.
