似乎每当为交叉构建更改Scala版本时，我设置的带有时间戳的

version

设置就会被清除

当我尝试交叉生成

publish

时，我使用以下命令：

sbt ";stamp-version ;+publish"

以下是命令的代码

戳记版本

：

object TimestampVersion {

  import Version.Snapshot

  lazy val versionSettings = Seq(commands += stampVersion)

  def stampVersion = Command.command("stamp-version") { state =>
    val extracted = Project.extract(state)
    extracted.append(List(version in ThisBuild ~= { ver =>
      val stmp = stamp(ver)
      Logging.info("Stamping version %s".format(stmp))
      stmp
    }), state)
  }

  def stamp(version: String): String = {
    if (version endsWith Snapshot) {
      // we use a dot here to not break rpm versioning rules
      (version stripSuffix Snapshot) + "." + timestamp(System.currentTimeMillis)
    } else {
      version
    }
  }

  def timestamp(time: Long): String = {
    // no delimiter between date & time in order to not break rpm versioning rules
    val sdf = new java.text.SimpleDateFormat("yyyyMMddHHmmss")
    sdf.setTimeZone(TimeZone.getTimeZone("UTC"))
    sdf.format(new Date(time))
  }
}

是否有其他方法可以存储跨构建访问的时间戳版本

编辑：为了清楚起见，我希望每个交叉构建的版本都有相同的时间戳，这样当我从其他地方使用它时，我可以像这样依赖它：

“x”%%“y”%%“z”

另外，如果该解决方案能够与SBT 0.12.x一起工作，那将是最好的，因为我仍然有这种依赖关系。

我不确定它是否是SBT

0.13.x中的推荐方法，但以下内容似乎对我来说很好
如果您需要对CrossScalarVersions
中列出的所有版本“具有相同的时间戳”，则您可能希望利用（即）和方法，以唯一的快照版本保存时间戳文件
注意不要在build.sbt
中设置scalaVersion
，因为它会覆盖+
设置的值。这就是我最初回答的问题
在build.sbt
中执行以下任务stampVersion
（我将其迁移到sbt<0.13作为练习）：
运行任务stampVersion
时，将在target/timestamp
文件中创建一个文件
通过以下任务，您可以阅读其内容
lazy val getStampVersion = taskKey[String]("Retrieves unique snapshot version from timestamp file")

getStampVersion := {
  val log = streams.value.log
  val file = (target in Compile).value / "timestamp"
  val v = IO.read(file)
  log.info(s"Retrieving version from $file: $v [scalaVersion: ${scalaVersion.value}]")
  v
}

使用show getStampVersion
显示保存在文件中的版本

为了将version
键设置为带时间戳的版本，我定义了一个命令setVersionFromStampFile
（当它更改项目状态时）
使用命令setVersionFromStampFile
，每当它运行时，version
就会被适当地设置
[sbt-0-13-1]> show version
[info] 0.1-SNAPSHOT
[sbt-0-13-1]> setVersionFromStampFile
[info] Retrieving version from /Users/jacek/sandbox/so/sbt-0.13.1/target/timestamp: 1390606523705 [scalaVersion: 2.10.3]

[info] Set current project to sbt-0-13-1 (in build file:/Users/jacek/sandbox/so/sbt-0.13.1/)
[sbt-0-13-1]> show version
[info] 1390606523705

在生成定义build.sbt
中，定义了设置交叉缩放
crossScalaVersions := Seq("2.9.3", "2.10.3")

在build.sbt
中定义命令别名setstampasversion并显示，以便于测试-执行命令setVersionFromStampFile
后，您将看到version
和scalaVersion
设置的值：
addCommandAlias("setStampAsVersionAndShow",
                "; setVersionFromStampFile ; show version; show scalaVersion")

这使您可以交叉执行一系列命令：
[sbt-0-13-1]> + setStampAsVersionAndShow

在build.sbt
中定义publishTo
设置和另一个命令别名setstampasversion和publish
：
publishTo := Some(Resolver.file("file", target.value / "xxx"))

addCommandAlias("setStampAsVersionAndPublish",
                "; setVersionFromStampFile ; show scalaVersion ; publish")

现在，您应该能够像预期的那样发布
：

我们可以像这样在bash中设置日期时间
export DATETIME=`date +"%Y-%m-%d_%H-%M-%S"`

然后像这样构建我们的软件
sbt 'set version in ThisBuild := s"1.0.0-${sys.env.get("DATETIME").get}"' +compile +publish

这将确保两个编译版本使用相同的时间戳。
谢谢Jacek。我更新了我应该更具体的问题。这个解决方案似乎对交叉构建的Scala的每个版本都有一个不同的时间戳组件，这对我来说并没有那么有用，因为很难依赖它。@myyk答案已更改以反映需求。当我回答你的问题（并掌握SBT）时，享受和我一样多的乐趣。感谢迄今为止所做的一切，这非常有帮助，当我完成后，我将分享我的0.12改编。不过，您的解决方案有一个问题，我也有同样的问题，它也存在于上面的输出中。设置为2.9.3版后，您可以看到它正在发布到sbt-0-13-1_2.10，这是错误的，它应该是sbt-0-13-1_2.9.3.更新的。它似乎工作得很好，scalaversation。试试看，回来汇报！如果您确实需要设置scalaVersion并拥有一个多项目构建，那么您可能必须将此构建中的scalaVersion设置为您想要的版本。我在设置stampVersion时读取了值，这对我很有用。
export DATETIME=`date +"%Y-%m-%d_%H-%M-%S"`
