从一台Fedora的电脑中拷过来一个project，在win10的Eclipse下选择Import->Existing Maven Projects，载入时却出现以下错误：
org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failed to collect dependencies for org.apache.maven.plugins:maven-resources-plugin:jar:2.6 () (org.apache.maven.plugins:maven-resources-plugin:2.6:resources:default-resources:process-resources)
这里提示的是Maven的maven-resources-plugin插件载入失败，进入C:\Users\yourname\.m2\repository\org\apache\maven\plugins文件下，找到maven-resources-plugin文件，缺失maven-resources-plugin.jar文件，于是笨拙地去官网下载了一个，刷新projet，重启Eclipse还是出现这样的错误。
在stackoverflow上找到了类似问题的解决方案，类似的，出现maven-compiler-plugin，maven-deploy-plugin，maven-clean-plugin等插件提示错误的，都可以遵循以下原则解决
1.清空C:\Users\yourname\.m2\repository 文件夹
2.右键此projet，Maven->Update projects，快捷键为Alt+F5，此步会重新生成respository文件夹，里边的插件自然会从官网自动下 载
3.关闭Eclipse，执行maven install
- install:install is used to automatically install the project's main artifact (the JAR, WAR or EAR), its POM and any attached artifacts (sources, javadoc, etc) produced by a particular project.
4.再次打开Eclipse，projec可以正常工作啦
