def initialize(prop, sh_name_prefix = "build")
@prop = prop
@build_props = prop["build"]
@jenkins_props = prop[:jenkins]
@sh_name = sh_name_prefix + ".sh"
求解@build_props = prop["build"] 这一句是什么意思 新人求解 万分感谢！！

推测可知，
prop是个hash之８的，
里面至少类似可能可以像是：
{'build' => 'abc', :jenkins => 123, 'otherHash' => {'a'=>1,'b'=>2}, 'otherArray' => [1,2,3]}
