Eclipse导入Maven项目出现：Could not calculate build plan: Plugin org.apache.maven.plugins:maven-war-plugin:2.2

错误如下：

Could not calculate build plan: Plugin org.apache.maven.plugins:maven-war-plugin:2.2 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-war-plugin:jar:2.2...

解决方法：

1、项目右键->【Maven】->【Update Project...】

把这个选上，最后点击【OK】进行升级

2、可以尝试把C:\Users\用户名\.m2\repository\org\apache\maven\plugins\maven-deploy-plugin目录删除。
