如何在Play框架中创建子项目? (play#play-java_2.9.2; 2.1-RC3:找不到) [英] How to create sub projects in Play Framework? (play#play-java_2.9.2;2.1-RC3: not found)

问题描述

我想测试子项目的工作方式，尤其是在主项目中如何考虑子项目的routes(

I want to test how sub projects work, especially how the routes of the sub project are taken into account in main project (this was not visible before).

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

I have read the docs here: https://github.com/playframework/Play20/wiki/SBTSubProjects

我做了什么:(下载play 2.1 RC3之后)

What have I done: (after downloading play 2.1 RC3)

1. 创建新的Java项目:play new MainProject
2. 在MainProject中创建新文件夹:modules
3. 创建新的Java项目:play new SubProject

1. Create new Java Project: play new MainProject
2. Create new folder inside MainProject: modules
3. Create new Java Project: play new SubProject

在两个项目上:play eclipse因为play eclipsify不再起作用

On both projects: play eclipse since play eclipsify does not work anymore

在主项目Build.scala文件中:

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，在主项目中运行:

Now, in the main project I run:

play run

我得到以下错误:

[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

注意 我试图从子项目中删除Build.scala，但是我一直收到此错误.

Note I have tried to delete the Build.scala from the subproject but I kep getting this error.

我在做什么错了?

推荐答案

最终使其正常工作:

• 您不必从子项目中删除Build.scala.

您需要重命名子项目的路由文件.在我的示例中，为subProject.routes.如果要单独运行子项目，则需要声明路由必须解析为subProject.routes.因此，将其添加到子项目的application.conf中:

You need to rename the routes file of your sub project. In my example, to subProject.routes. If you want to run your subproject in isolation you need to declare that routes must resolve to your subProject.routes. So add this in the application.conf of your subProject:

application.router=subProject.Routes

在您的主项目中，您需要从子项目中导入路线:

In your main project, you need to import the routes from the subproject:

->  /subProject               subProject.Routes

主项目的构建文件应类似于:示例来自SCALA，但s

And the build file of the main project should look something like: 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)

}
