google-app-engine - 应用引擎去部署失败

Question

昨天下午还好好的，现在不行了。我使用goapp deploy MY_DIR/app.yaml进行部署，这是部署的消息

02:38 PM Host: appengine.google.com02:38 PM Application: MY_APP; module: MY_MOD; version: MY_VER02:38 PM Starting update of app: exp-lkl, module: MY_MOD, version: MY_VER02:38 PM Getting current resource limits.02:38 PM Scanning files on local disk.02:38 PM Scanned 500 files.02:38 PM Scanned 1000 files.02:38 PM Cloning 1085 application files.02:38 PM Compilation starting.02:38 PM Compilation: 1081 files left.02:38 PM Compilation completed.02:38 PM Starting deployment.02:38 PM Checking if deployment succeeded.02:38 PM Will check again in 1 seconds.02:38 PM Checking if deployment succeeded.02:38 PM Will check again in 2 seconds.02:38 PM Checking if deployment succeeded.02:38 PM Will check again in 4 seconds.02:38 PM Checking if deployment succeeded.02:38 PM Will check again in 8 seconds.02:38 PM Checking if deployment succeeded.02:38 PM Will check again in 16 seconds.02:38 PM Checking if deployment succeeded.02:39 PM Deployment successful.02:39 PM Checking if updated app version is serving.02:39 PM Rolling back the update.Error 500: --- begin server output ---
Server Error
A server error has occurred.
--- end server output ---

我也试过:
1/更新sdk到最新版本
2/更新go版本(我试过go1.6和go1.8)
3/使用appcfg.py
但是我得到了同样的错误
有人可以帮忙吗？

终于解决了这个问题。App Engine 似乎更改了不可构建代码的错误消息。我的项目没有构建，应用引擎之前显示了不可构建代码的路径，但现在应用引擎返回 500 错误
Error 500:
--- begin server output ---
<h3>Server Error</h3><p>A server error has occurred.</p>
--- end server output ---
