playframework - 为什么 PlayFramework 只有 "eclipse"一个子模块？

Question

使用 Play Framework 2.1.1-RC1，我将一个项目分成多个模块，如下所示:

object ApplicationBuild extends Build {

  val appName         = "Project"
  val appVersion      = "1.0"

  val appDependencies = Seq(
    // Add your project dependencies here,
    javaCore,
    javaJdbc,
    javaEbean,
    "mysql" % "mysql-connector-java" % "5.1.18"
  )

  lazy val common = play.Project(
    appName + "-common", appVersion, appDependencies, path = file("modules/common")
  ).settings(
    publishArtifact in(Compile, packageDoc) := false
  )

  lazy val website = play.Project(
    appName + "-website", appVersion, appDependencies, path = file("modules/website")
  ).dependsOn(common).aggregate(common).settings(
    requireJs += "app.js",

    publishArtifact in(Compile, packageDoc) := false
  )

  lazy val api = play.Project(
    appName + "-api", appVersion, appDependencies, path = file("modules/api")
  ).dependsOn(common).aggregate(common).settings(
    publishArtifact in(Compile, packageDoc) := false
  )

  val main = play.Project(appName, appVersion, appDependencies).settings(
    publishArtifact in(Compile, packageDoc) := false
  ).dependsOn(website, api).aggregate(website, api)
}

所以，当我调用 play eclipse 时，它应该使所有三个子模块都消失，但只编译第一个，你知道为什么吗？

这是游戏的转储:

$ /opt/play/2.1.1-RC1/play eclipse
  [info] Loading project definition from /mnt/data/dev/perso/Project/project
  [info] Set current project to Project (in build file:/mnt/data/dev/perso/Project/)

  [info] Resolving org.hibernate.javax.persistence#hibernate-jpa-2.0-api;1.0.1.Fin                                                                                [info] Done updating.                                                        
  [info] Compiling 27 Java sources to /mnt/data/dev/perso/Project/modules/common/target/scala-2.10/classes...
  [info] Successfully created Eclipse project files for project(s):
  [info] Project-common
$

为什么？有什么理由吗？

如果我运行该项目，一切正常，每个模块都正常工作。

我错过了什么？

好的，@Stijn 来自 Google Group discussion 的一个很好的指示PlayFramework，我找到了解决方案。

使用 PlayFramework documentation ，您有两种构建所有子模块的选择:

选项 1:

进入 play 控制台，然后调用 eclipse skip-parents=false :

$ /path/to/playframework/play
[PlayProject] $ eclipse skip-parents=false

警告!在 play console 之外执行此操作不起作用:

$ /path/to/playframework/play eclipse skip-parents=false
> [error] Not a valid key: skip-parents (similar: ivy-paths)
> [error] skip-parents=false

选项 2:

修改 Build.scala :

import com.typesafe.sbteclipse.core.EclipsePlugin.EclipseKeys

object ApplicationBuild extends Build {

  override def settings = super.settings ++ Seq(
      EclipseKeys.skipParents in ThisBuild := false
  )

  ...

}

不要忘记导入 EclipseKeys!

希望这对您有所帮助!
