“mfp push”在部署适配器时抛出 NullPointerException (MobileFirst Platform 7.1)

Question

使用 MobileFirst Platform CLI 版本 7.1.0.00.20151227-1730 在尝试推送我对适配器所做的更新时突然出现以下错误：

    Preparing for push...
Verifying Server Configuration...
Runtime 'localMFP' will be used to push the project into.

我已尝试清理项目，删除已部署的内容，将更改恢复为成功部署时所做的更改，重新安装 mfp cli，但问题仍然存在。

关于我可以做些什么来摆脱异常的任何提示？

谢谢！

故障来自升级程序代码路径，好像适配器文件中缺少某些内容。

我的建议是创建一个新适配器并查看它是否已部署。然后，开始添加回代码。也许你会找到失败的部分。
