Playframework 具有2个不同版本的多项目

我需要开发以下内容：

playframework应用程序

阿克卡http

共享库

play和akka应用程序都需要#3共享库

是否可以在一个sbt项目中创建两个不同的版本

因此，当我运行play build时，它不会包含akka，当我运行akka build时，它不会包含play代码

---

我只想避免打开和管理两个不同的项目。

我使用包含3个子项目的多项目结构：

Root

build.sbt

：

lazy val myLib = (project in file("my-lib"))

lazy val playJava = (project in file("play-java"))
  .enablePlugins(PlayJava)
  .dependsOn(myLib)

lazy val runnableApp = (project in file("runnable-app"))
  .dependsOn(myLib)

name := """play-java"""

version := "1.0-SNAPSHOT"

scalaVersion := "2.11.7"

name := """runnable-app"""

version := "1.0"

scalaVersion := "2.11.6"

mainClass in assembly := Some("com.example.Hello")

assemblyOption in assembly := (assemblyOption in assembly).value.copy(includeScala = false)

libraryDependencies ++= Seq(
  "junit"             % "junit"           % "4.12"  % "test",
  "com.novocode"      % "junit-interface" % "0.11"  % "test"
)

name := """my-lib"""

version := "1.0"

scalaVersion := "2.11.7"

libraryDependencies ++= Seq(
  "junit"             % "junit"           % "4.12"  % "test",
  "com.novocode"      % "junit-interface" % "0.11"  % "test"
)

其中

myLib

library，应该在play应用程序

playJava

和简单java项目

runnableApp

1.播放

build.sbt

：

lazy val myLib = (project in file("my-lib"))

lazy val playJava = (project in file("play-java"))
  .enablePlugins(PlayJava)
  .dependsOn(myLib)

lazy val runnableApp = (project in file("runnable-app"))
  .dependsOn(myLib)

name := """play-java"""

version := "1.0-SNAPSHOT"

scalaVersion := "2.11.7"

name := """runnable-app"""

version := "1.0"

scalaVersion := "2.11.6"

mainClass in assembly := Some("com.example.Hello")

assemblyOption in assembly := (assemblyOption in assembly).value.copy(includeScala = false)

libraryDependencies ++= Seq(
  "junit"             % "junit"           % "4.12"  % "test",
  "com.novocode"      % "junit-interface" % "0.11"  % "test"
)

name := """my-lib"""

version := "1.0"

scalaVersion := "2.11.7"

libraryDependencies ++= Seq(
  "junit"             % "junit"           % "4.12"  % "test",
  "com.novocode"      % "junit-interface" % "0.11"  % "test"
)

2.runnableApp

build.sbt

：

lazy val myLib = (project in file("my-lib"))

lazy val playJava = (project in file("play-java"))
  .enablePlugins(PlayJava)
  .dependsOn(myLib)

lazy val runnableApp = (project in file("runnable-app"))
  .dependsOn(myLib)

name := """play-java"""

version := "1.0-SNAPSHOT"

scalaVersion := "2.11.7"

name := """runnable-app"""

version := "1.0"

scalaVersion := "2.11.6"

mainClass in assembly := Some("com.example.Hello")

assemblyOption in assembly := (assemblyOption in assembly).value.copy(includeScala = false)

libraryDependencies ++= Seq(
  "junit"             % "junit"           % "4.12"  % "test",
  "com.novocode"      % "junit-interface" % "0.11"  % "test"
)

name := """my-lib"""

version := "1.0"

scalaVersion := "2.11.7"

libraryDependencies ++= Seq(
  "junit"             % "junit"           % "4.12"  % "test",
  "com.novocode"      % "junit-interface" % "0.11"  % "test"
)

3.myLib

build.sbt

：

lazy val myLib = (project in file("my-lib"))

lazy val playJava = (project in file("play-java"))
  .enablePlugins(PlayJava)
  .dependsOn(myLib)

lazy val runnableApp = (project in file("runnable-app"))
  .dependsOn(myLib)

name := """play-java"""

version := "1.0-SNAPSHOT"

scalaVersion := "2.11.7"

name := """runnable-app"""

version := "1.0"

scalaVersion := "2.11.6"

mainClass in assembly := Some("com.example.Hello")

assemblyOption in assembly := (assemblyOption in assembly).value.copy(includeScala = false)

libraryDependencies ++= Seq(
  "junit"             % "junit"           % "4.12"  % "test",
  "com.novocode"      % "junit-interface" % "0.11"  % "test"
)

name := """my-lib"""

version := "1.0"

scalaVersion := "2.11.7"

libraryDependencies ++= Seq(
  "junit"             % "junit"           % "4.12"  % "test",
  "com.novocode"      % "junit-interface" % "0.11"  % "test"
)

在sbt会话中，我们可以选择项目。例如：

$ project playJava
[info] Set current project to play-java ...

现在我们可以在当前子项目上运行任务
