提供部分输入，来自设置到输入任务

Question

通过这段摘录，我尝试使用来自设置的一些预先应用的输入创建第二个inputKey：

val foo = inputKey[Unit]("....")
foo := { ... }
val foo2 = inputKey[Unit]("....")
foo2 := {
    foo.partialInput(" "+name.value).evaluated
}

但是我收到了Illegal dynamic reference错误，因为如果我使用partialInput，evaluated的参数必须是常量。

解决这个问题的最佳方法是什么？

类似的问题，我以前读过：

• combining input task with dynamic task in sbt
• SBT How to pass input from one inputTask to another inputTask
• How to call inputTask from within another inputTask?

使用SBT 0.13.7。

此示例中显示的技术取自SBT参考文档不起作用：

lazy val run2 = inputKey[Unit]("Runs the main class twice: " +
   "once with the project name and version as arguments"
   "and once with command line arguments preceded by hard coded values.")

// The argument string for the first run task is ' <name> <version>'
lazy val firstInput: Initialize[String] =
   Def.setting(s" ${name.value} ${version.value}")

// Make the first arguments to the second run task ' red blue'
lazy val secondInput: String = " red blue"

run2 := {
   val one = (run in Compile).fullInput(firstInput.value).evaluated
   val two = (run in Compile).partialInput(secondInput).evaluated
}
