问题描述

在创建或者导入Maven工程包时，出现如下错误：

Could not calculate build plan: Plugin org.apache.maven.plugins:maven-war-plugin:3.1 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-war-plugin:jar:3.1

Plugin org.apache.maven.plugins:maven-war-plugin:3.1 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-war-plugin:jar:3.1

解决方式:

（1）清除错误仓库：

查看windows -> Preferences -> maven 的settings.xml文件中.m2的位置：

（默认为：C:\Users\用户名\.m2\repository\org\apache\maven\plugins\maven-war-plugin\3.1)
         目录下的m2e-lastUpdated.properties文件;

或者直接将plugins目录下文件夹删除

（2）项目右键，Run As-->Maven clean

（3）项目右键，Maven-->Update Project 重新下载依赖包

（4）刷新工程即可
