Question

我想覆盖run任务的默认行为，以便预处理传递给sbt命令的参数，并在具有不同参数的特定子项目上调用run任务（取决于自定义逻辑）。这是build.sbt文件的一个示例：

lazy val core = (project in file("core"))
lazy val bar = (project in file("bar"))
lazy val foo = (project in file("foo"))
run := Runner.buildRunTask(bar, foo).value.evaluated

buildRunTask使用新实现覆盖任务。代码如下：

    def buildRunTask(runnableProjects:Project*) : Initialize[InputTask[Unit]] = 
    Def.inputTask { 
        val args: Seq[String] = spaceDelimited("<arg>").parsed
        val availableProjects = runnableProjects.map(_.id).mkString(",")
        if (args.length == 0) throw new IllegalStateException(s"you need to specify a valid command. Available commands are: '$availableProjects'")

        val command = args head
        val project = runnableProjects.find(_.id == command)
          .getOrElse(throw new IllegalStateException(s"invalid command '$command'. Available command are: $availableProjects"))

        val newArgs = transformArgs(args.rest)

        //TODO: how I can compile and execute the run task only for the project passed as argument? I want something like project.runTask(newArgs) ?
    }

你有什么建议吗？

谢谢！
