通过 James Ward 的Play2Tutorial，我完成了最后一步，添加 Postgresql 数据库并推送到 Heroku。

我根据他的建议编辑了 Build.scala 文件：

val appDependencies = Seq(
    "com.github.twitter" % "bootstrap" % "2.0.2",
    "postgresql" % "postgresql" % "9.1-901-1.jdbc4"
  )

并修改了我的 Procfile：

web: target/start -Dhttp.port=${PORT} -DapplyEvolutions.default=true -Ddb.default.driver=org.postgresql.Driver -Ddb.default.url=$DATABASE_URL ${JAVA_OPTS}

编译器在 localhost 上没有返回任何错误，Heroku postgresql 似乎添加得很好，但是“git push heroku master”在最后一刻失败了：

[info] Resolving org.scala-sbt#precompiled-2_9_2;0.11.3 ...
   [info] Done updating.

Heroku push rejected, failed to compile Play 2.0 - java app

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

该代码是文字复制和粘贴，我之前已经使用过它（已经完成了本教程，没有发生任何事故）。

希望您能提供任何建议。

谢谢，芯片

Looks like the separating comma of your dependencies in Build.scala file is not found on Heroku. Are you sure you have pushed the latest version of the Build.scala file to Heroku?
