將play2 yeoman應用推送至Heroku

Question

試圖將play2-yeoman推送至heroku。 作爲討論here，我做了以下

1. 的Heroku創建--buildpack https://github.com/47deg/heroku-buildpack-scala.git

我看到下面的

Creating frozen-springs-5883... done, stack is cedar 
BUILDPACK_URL=https://github.com/47deg/heroku-buildpack-scala.git 
http://frozen-springs-5883.herokuapp.com/ | git@heroku.com:frozen-springs-5883.git 

我看着分叉buildpack，它使用一個叫做變量$ {UI_FILES}，所以我補充說，以heroku配置使用

heroku config:set UI_FILES=ui 

然而，當我試圖把我收到以下錯誤消息

Initializing repository, done. 
Counting objects: 889, done. 
Delta compression using up to 4 threads. 
Compressing objects: 100% (367/367), done. 
Writing objects: 100% (889/889), 1.24 MiB | 2.17 MiB/s, done.

-----> Fetching custom git buildpack... done 

!  Push rejected, no Cedar-supported app detected 

To git@heroku.com:frozen-springs-5883.git 
! [remote rejected] master -> master (pre-receive hook declined) 
error: failed to push some refs to 'git@heroku.com:frozen-springs-5883.git' 

Answer 1

據Heroku's devcenter，您可以強制的Heroku通過執行以下命令，使用該播放2 buildpack建：

heroku config:add BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-scala.git
