maven新建子聚合项目时报错

Could not calculate build plan: Plugin org.apache.maven.plugins:maven-resources-plugin:2.5 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.5
Plugin org.apache.maven.plugins:maven-resources-plugin:2.5 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.5

解决方法：

可以尝试删除maven本地库里面的org.apache.maven.plugins:maven-resources-plugin所在目录，让mavan重新下载这个包就行了。

I fixed it by deleting all the files under de .m2 repository folder. The next time I built the project I had to download all the dependencies again but it was worth it - 0 errors!!
