在SBT中交叉构建时设置唯一的快照版本

myy*_*yyk 9 scala sbt

如果publish,如果有-SNAPSHOT一个版本,我想了一个独特的时间戳来代替它.我已经完成了这个并且它有效,除了用于交叉构建+.

似乎version每当为交叉构建更改Scala版本时,我设置的时间戳设置都会被清除.

当我尝试交叉构建时,publish我使用以下命令:

sbt ";stamp-version ;+publish"

以下是该命令的代码stamp-version:

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))
  }
}

我可以通过不同的方式存储可以通过交叉构建访问的带时间戳的版本吗？

编辑:要清楚,我希望每个交叉构建版本具有相同的时间戳,以便当我从其他地方使用它时,我可以依赖于这样: "x" %% "y" % "z"

此外,如果解决方案可以与SBT 0.12.x一起使用,那将是最好的,因为我仍然具有该依赖性.

我不确定它是否是SBT推荐的方法0.13.x,但以下似乎对我来说效果很好.

如果您需要为列出的所有版本"具有相同的时间戳"crossScalaVersions,那么您可能希望利用生成文件(即IO.write和IO.read方法)来保存具有唯一快照版本的时间戳文件.

注意不要设置scalaVersion,build.sbt因为它会覆盖设置的那个+.这是我最初的答案中的问题.

有以下任务stampVersion的build.sbt(我把它迁移到SBT <0.13作为练习):

lazy val stampVersion = taskKey[File]("Generates timestamp file with unique snapshot version")

stampVersion := {
  val log = streams.value.log
  val stmp = System.currentTimeMillis
  val file = target.value / "timestamp"
  log.info(s"Stamping version $stmp saved in $file")
  IO.write(file, s"""$stmp""")
  file
}

运行任务时stampVersion,将在target/timestamp文件中创建文件.

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(因为它改变了项目的状态).

def setVersionFromStampFile = Command.command("setVersionFromStampFile") { state =>
  val e = Project extract state
  import e._
  val (newState, stampVersion) = runTask(getStampVersion, state)
  val scalaV = scalaVersion in currentRef get structure.data getOrElse Nil
  state.log.info(s"scalaVersion: $scalaV")
  val settings = Seq(
    version := stampVersion
  )
  append(settings ++ structure.settings, state)
}

commands += setVersionFromStampFile

使用该命令setVersionFromStampFile,无论何时运行,version都会得到适当的设置.

定义命令别名setStampAsVersionAndShow在build.sbt缓解测试-你会看到的价值version和scalaVersion执行命令后设置setVersionFromStampFile:

addCommandAlias("setStampAsVersionAndShow",
                "; setVersionFromStampFile ; show version; show scalaVersion")
