deployment - 无法将 Play 应用程序部署到 Heroku

Question

我在将 Play 应用程序部署到 Heroku 时遇到问题。我在没有模块的情况下部署其他基本应用程序没有问题，但是这个给了我以下错误:

       http://billeteo.herokuapp.com deployed to Heroku

To git@heroku.com:billeteo.git
   53b789c..24f66a4  master -> master

尽管我是从项目的根目录运行，但 Heroku 认为我的根目录位于:

 Play! application root found at ./mods/playcopy/crud-1.2.3/

当然，其中不包含代码并且过程失败。

我的应用程序是具有以下 dependencies.xml 的标准 Play 应用程序:

# Application dependencies
# Notes:
#   play is an alias for play -> play $currentVersion
#   play -> crud is an alias for play -> crud $currentVersion
#   play -> secure is an alias for play -> secure $currentVersion
#   Modules from the main repository use 'play' as organisation

require:
    - play
    - playcopy -> crud 1.2.3
    - playcopy -> betterlogs 1.0
    - playcopy -> cobertura 2.1
    - playcopy -> mockito 0.1
    - playcopy -> greenscript 1.2.6h
    - custom -> useragentcheck 1.0
    - org.hibernate -> hibernate-search 3.4.0.Final

repositories:
     - localModules:
         type:       local
         artifact:   "${application.path}/mods/[organisation]/[module]-[revision]"
         contains:
           - playcopy
           - custom

我正在为一些官方 Play 模块使用本地存储库，因为它们可能有一些自定义代码(删除一些不必要的类、更改安全性、一些日志等)。

任何人都知道如何让 Heroku 找到正确的根？在谷歌上找不到任何东西...

Heroku 上的 Play 设置并没有预料到您在此处的特定设置。就像您指出的那样，它对您的应用程序的根目录在哪里感到困惑。我认为我们可以推出一个修复程序来解决这个问题，但与此同时，你应该能够解决它。试试这个:

压缩您的自定义模块并将您的 dependencies.yml 文件更改为

...
repositories:
 - localModules:
     type:       local
     artifact:   "${application.path}/mods/[organisation]/[module]-[revision].zip"
     contains:
       - playcopy
       - custom
...

在依赖解析期间，Play 应该解压缩您的自定义模块并将它们放在正确的位置。此外，Heroku 不应该对应用程序的根目录在哪里感到困惑。
