eclipse maven error: Archive for required library in project cannot be read or is not a valid ZIP fi

eclipse 中maven 项目报错（console中problems视窗）:

1.Description Resource Path Location Type

Archive for required library: 'D:/maven/MavenRepository/maven_jar/commons-collections/commons-collections/3.2.2/commons-collections-3.2.2.jar' in project 'MR_Maven' cannot be read or is not a valid ZIP file MR_Maven Build path Build Path Problem


2.Description Resource Path Location Type

Archive for required library: 'D:/maven/MavenRepository/maven_jar/net/java/dev/jets3t/jets3t/0.9.0/jets3t-0.9.0.jar' in project 'MR_Maven' cannot be read or is not a valid ZIP file MR_Maven Build path Build Path Problem

可能是由于网络问题下载的jar包完整，需要先手工删除，步骤:

1.找到控制台console提示的相关错误jar提示的路径

2.删除jar文件或整个文件夹

3.进入eclipse ，在相应项目上右键 选择run as->maven-install. 将会重新下载正确的完整jar包.
