無法將Play 2.2.2應用程序部署到Heroku

Question

嘗試將我的Pl​​ay 2.2.2應用程序部署到Heroku時出現以下錯誤。

158-37-227-60:Bachelorprosjekt Magne$ heroku create --buildpack https://github.com/heroku/heroku-buildpack-scala.git 
Creating murmuring-scrubland-2494... done, stack is cedar 
BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-scala.git

158-37-227-60:Bachelorprosjekt Magne$ git push heroku master 
fatal: 'heroku' does not appear to be a git repository 
fatal: Could not read from remote repository. 

Please make sure you have the correct access rights 
and the repository exists. 
158-37-227-60:Bachelorprosjekt Magne$ git remote add heroku git@heroku.com:murmuring-scrubland-2494.git 
158-37-227-60:Bachelorprosjekt Magne$ git push heroku master

! [remote rejected] master -> master (pre-receive hook declined) 
error: failed to push some refs to 'git@heroku.com:murmuring-scrubland-2494.git' 

我Procfile看起來是這樣的：

web: target/universal/stage/bin/Bachelorprosjekt -Dhttp.port=$PORT 

我一直在到處尋找一個解決這一點，但類似的問題的解決方案並沒有幫助我至今：S

更新：當我嘗試部署時未指定構建包時，Heroku嘗試將其部署爲Play 1.2.7應用程序，而不是實際的Play 2.2.2應用程序。很顯然，每次部署都會失敗。這是我得到的輸出：

Answer 1

已解決。 Heroku無法使用當前項目結構部署我的項目時出現問題。我的項目位於另一個文件夾內，必須位於Heroku的根級才能成功部署應用程序。

Answer 2

作爲stated由heroku本身，它是不可能在子文件夾中的項目。

但是，你可以使用git subtree參數將子文件夾推送到herokus根目錄。

git subtree push --prefix subfoldername heroku master
