正则表达式获取Maven依赖中的groupId

用于打包时剔除第三方jar包

mvn dependency:tree | grep '[\W\w]*:[a-zA-Z0-9_\.-]*:[a-zA-Z0-9]*:[a-zA-Z0-9\.-]*:[a-zA-Z0-9]*' | sed 's/\[INFO\] //g' | sed 's/+- //g' | sed 's/|  //g' | sed 's/\\- //g' | sed 's/ //g'| sed 's/:/,:/g' | cut -d ":" -f1 | sort | uniq

比如，通过mvn dependency:tree只能获取如下内容

[INFO] Scanning for projects...
