背景
公司jenkins smoke test 每天日常运行中，但是在出错查看流程时日志繁琐，不易查找步骤，故简单优化pipeline使Jenkins日志更可读.

// flatten function hack included in case Jenkins security
// is set to preclude calling Groovy flatten() static method
// NOTE: works well on all nested collections except a Map
def msgFlatten(def list, def msgs) {
list = list ?: []
if (!(msgs instanceof String) && !(msgs instanceof GString)) {
msgs.each { msg ->
list = msgFlatten(list, msg)
}
}
else {
list += msgs
}
return list
}
在每个阶段起始处（或者在阶段中的特定位置），只需调用 echoBanner：
1
echoBanner("Stage Flow", ["Checkout GitLab!"])
显示如下

Stage Flow
Checkout GitLab!
