Scala 是否可以从sbt重新启动和测试xsbti.AppMain派生的应用程序？

我在按习惯发展。 问题是，每次我想测试它时，我都必须删除以前发布的

boot

目录，然后重新编译并在本地发布工件，最后运行应用程序并手动测试。其中一部分是通过运行外部shell脚本来完成的

我怎样才能让

sbt

为我做这项工作？我已经为它创建了骨架命令：

  lazy val root = Project(
    id       = "app",
    base     = file("."),
    settings = buildSettings ++ Seq( resolvers := rtResolvers,
      libraryDependencies ++= libs,
      scalacOptions  ++= Seq("-encoding", "UTF-8", "-deprecation", "-unchecked"),
      commands ++= Seq(launchApp))
  )


  val launchApp = Command.command("launch") { state =>
    state.log.info("Re-launching app")
    state
  }

在项目的主目录中创建文件，例如

fqb.build.properties

创建启动应用程序的脚本

#!/usr/bin/env bash

java -jar /path/to/sbt-launch.jar "$@"

定义任务和命令：

lazy val launcherTask = TaskKey[Unit]("launch", "Starts the application from the locally published JAR")

lazy val launchApp: Seq[Setting[_]] = Seq(
    commands += Command.command("publish-launch") { state =>
    state.log.info("Re-launching app")
    val modulesProj = modules.id
    s"$modulesProj/publishLocal" ::
      "publishLocal" ::
      launcherTask.key.label ::
      state
  },
  launcherTask := {
    "launch @fqb.build.properties" !<
  }
)

请记住在重新部署时删除旧的

~/.

目录，以便更改生效

lazy val root = Project(
    id       = "app",
    base     = file("."),
    settings = buildSettings ++ Seq( resolvers := rtResolvers,
      libraryDependencies ++= libs,
      scalacOptions  ++= Seq("-encoding", "UTF-8", "-deprecation", "-unchecked"),
      launchApp)
)
