使用不同的设置调用TaskKey

Question

我正在使用插件sbt-assembly（版本0.13.0），我想根据assemblyPackageDependency appendContentHash与InputKey联系起来lazy val isGlobalCached = InputKey[Boolean]("") lazy val myTask = taskKey[sbt.File]("myTask") myTask := { if (isGlobalCached.value) //run with the modified assemblyOption //assemblyOption in assemblyPackageDependency ~= { x => x.copy(appendContentHash = true) } assemblyPackageDependency.value else assemblyPackageDependency.value } p>

基本上，我想做这样的事情：

assemblyOption

但我不知道如果条件为真，而不是全局

，如何设置lazy val isGlobalCached = InputKey[Boolean]("") lazy val myTask = taskKey[sbt.File]("myTask") lazy val assemblyPackageDependencyWithHash = taskKey[sbt.File]("assemblyPackageDependencyWithHash") assemblyPackageDependencyWithHash <<= assemblyPackageDependency assemblyOption in assemblyPackageDependencyWithHash ~= { x => x.copy(appendContentHash = true) } myTask := { //run with the modified assemblyOption if (isGlobalCached.value) assemblyPackageDependencyWithHash.value else assemblyPackageDependency.value }

以下是我试过的一些不起作用的事情：

lazy val isGlobalCached = InputKey[Boolean]("")

lazy val myTask = taskKey[sbt.File]("myTask")

lazy val globalCacheConf = config("globalCacheConf")

assemblyOption  in globalCacheConf := (assemblyOption in assemblyPackageDependency).value.copy(appendContentHash = true)

myTask := {
    //run with the modified assemblyOption
    if (isGlobalCached.value)
        assemblyPackageDependency.in(globalCacheConf).value
    else
        assemblyPackageDependency.value
}
