无法将播放教程部署到 Heroku

Question

我正在尝试完全按照教程所说的去做，但我一直遇到这个错误。 该教程是第一个要做的事情。 （所以来源和in here完全一样）

！使用 sbt 构建应用程序失败 ！ Heroku push 被拒绝，无法编译 Play 2.x - java app

Answer 1

好的，看来我的问题只是项目/Build.scala 文件，这是一个工作版本：

import sbt._
import Keys._
import play.Project._

object ApplicationBuild extends Build {

  val appName         = "todolist"
  val appVersion      = "1.0-SNAPSHOT"

  val appDependencies = Seq(
    // Add your project dependencies here,
    javaCore,
    javaJdbc,
    javaEbean,
    "postgresql" % "postgresql" % "9.1-901.jdbc4"
  )

  val main = play.Project(appName, appVersion, appDependencies).settings(
    // Add your own project settings here      
  )

}

我关注了this tutorial，但没有正确理解如何设置 Build.scala 文件。
