如何防止同一个.travis.yml需要一遍又一遍地复制到每个仓库？

Question

背景：目前有多个模块：puppet-sftp，puppet-git，puppet-packer和puppet-otto使用相同的.travis。 YML。

目标：创建common .travis.yml而不是一遍又一遍地复制

方法：

1. 已创建common git repo
使用travis 在每个项目中克隆
2. This repo

   结果：

   The command "ls" exited with 0.
   
   $ npm ansible-common-test/test
   
   Usage: npm <command>
   
   where <command> is one of:
   
       add-user, adduser, apihelp, author, bin, bugs, c, cache,
   
       completion, config, ddp, dedupe, deprecate, docs, edit,
   
       explore, faq, find, find-dupes, get, help, help-search,
   
       home, i, info, init, install, isntall, issues, la, link,
   
       list, ll, ln, login, ls, outdated, owner, pack, prefix,
   
       prune, publish, r, rb, rebuild, remove, repo, restart, rm,
   
       root, run-script, s, se, search, set, show, shrinkwrap,
   
       star, stars, start, stop, submodule, t, tag, test, tst, un,
   
       uninstall, unlink, unpublish, unstar, up, update, v,
   
       version, view, whoami

   讨论：

   来自.travis.yml的重复代码被移动到一个公共仓库，既不能运行.sh也不能运行yml。无论尝试什么，似乎都无法从通用仓库运行travis代码以避免代码重复。

   期望如下：

   1. 包含每个仓库使用的.travis.yml的公共仓库由travis克隆
   2. 运行公共代码
