报错：Error resolving version for plugin 'org.apache.maven.plugins:maven-eclipse-plugin' from the repositories，查找后发现本地用户目录仓库下只有maven-eclipse-plugin文件夹，并没有jar包
本地仓库没有maven-eclipse-plugin jar包，没装上maven-eclipse-plugin,解决
在项目的根目录添加：
修改pop.xml
<build>
<pluginManagement>
<plugins>
<plugin>
<artifactId>maven-eclipse-plugin</artifactId>
<version>2.10</version>
<configuration>
<pde>true</pde> 安装玩后改成false，true位从远程仓库拿包
</configuration>
</plugin>
</plugins>
</pluginManagement>
</build>
整改pom.xl
