playframework-2.0 - 如何在 Play Framework 中创建子项目？ (play#play-java_2.9.2;2.1-RC3 : not found)

Question

我想测试子项目是如何工作的，尤其是 routes在主项目 ( this was not visible before ) 中考虑了子项目的数量。

我在这里阅读了文档:
https://github.com/playframework/Play20/wiki/SBTSubProjects

我做了什么:(下载 play 2.1 RC3 后)

创建新的 Java 项目:play new MainProject

在 MainProject 中创建新文件夹:modules

创建新的 Java 项目:play new SubProject

两个项目: play eclipse自 play eclipsify不再工作

在主要项目 Build.scala文件:

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

object ApplicationBuild extends Build {

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

  val appDependencies = Seq(
    // Add your project dependencies here,
    javaCore,
    javaJdbc,
    javaEbean 
  )

  val subProject = Project("subproject", file("modules/SubProject"))

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

}

现在，在我运行的主项目中:

play run

我收到以下错误:

[error] (MainProject/*:update) sbt.ResolveException: unresolved dependency: play#play_2.9.2;2.1-RC3: not found
[error] unresolved dependency: play#play-java_2.9.2;2.1-RC3: not found
[error] unresolved dependency: play#play-java-jdbc_2.9.2;2.1-RC3: not found
[error] unresolved dependency: play#play-java-ebean_2.9.2;2.1-RC3: not found
[error] unresolved dependency: play#play-test_2.9.2;2.1-RC3: not found

笔记
我试图删除 Build.scala来自子项目，但我一直收到这个错误。

我究竟做错了什么？

终于让它工作了:

您不必删除 Build.scala从子项目。

您需要重命名子项目的路由文件。在我的例子中，到 subProject.routes .如果您想独立运行您的子项目，您需要声明路由必须解析为您的 subProject.routes。所以在 application.conf 中添加这个您的子项目:

application.router=subProject.Routes

在您的主项目中，您需要从子项目导入路由:

->  /subProject               subProject.Routes

并且主项目的构建文件应该类似于:example is from SCALA but s

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

object ApplicationBuild extends Build {

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

  val appDependencies = Seq(
    // Add your project dependencies here,
   javaCore,
   javaJdbc,
   javaEbean 
  )

  val subProject = play.Project(
    appName + "-subProject", appVersion, path = file("modules/SubProject")
  )

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

}
