eclipse导入maven project问题整理

1.Plugin execution not covered by lifecycle configuration: org.apache.rat:apache-rat-plugin:0.12:check (execution: validate, phase: validate)

在标签外加上标签，如下：

    
        
            ....
        
    

2.Failure to transfer org.apache.maven.plugins:maven-war-plugin:pom:2.6 from http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.apache.maven.plugins:maven-war-plugin:pom:2.6 from/to central (http://repo.maven.apache.org/maven2): The operation was cancelled.

这个问题是因为maven的plugin下没有找到对应的jar包，找到plugin对应的目录C:\User\.m2\repository\org\apache\maven\plugins\maven-war-plugin\2.6，没有找到maven-war-plugin-2.6.jar，这就是报错的原因，直接将C:\Users\Yuan\.m2\repository\org\apache\maven\plugins\maven-war-plugin下的2.6目录删除，然后右键项目，Maven  -> update project，此时再看C:\User\.m2\repository\org\apache\maven\plugins\maven-war-plugin\2.6目录下，应该已经出现了maven-war-plugin-2.6.jar，诸如此类报plugin没找到的错误，都是这样的解决方法。
