Play Framework 2.5 子项目端口配置

Question

我正在开发一个包含 4 个子项目的项目：

root-project:
-backend (play)
-frontend (play)
-akka-system (scala akka)
-common (messages to communicate between play projects and akka)

我在 Build.sbt 中这样配置 runAll 任务：

val runAll = inputKey[Unit]("Runs all subprojects")

runAll := {
  (run in Compile in frontend).evaluated
  (run in Compile in backend).evaluated
  (run in Compile in `akka-system`).evaluated
}

问题是我如何在任务中传递 -Dhttp.port 参数来运行前端与后端不同的端口？

Answer 1

试试这样的

runAll := {
  (run in Compile in frontend).partialInput(" 5000").evaluated
  (run in Compile in backend).partialInput(" 6000").evaluated
  (run in Compile in `akka-system`).evaluated
}
