Установка уникальной версии снимка при перекрестном построении в SBT

Когда publish, Если там есть -SNAPSHOT в версии я хотел бы заменить его на уникальную метку времени. Я уже сделал это, и это работает, за исключением перекрестного построения с +,

Кажется, что version настройка, которую я установил с помощью метки времени, очищается при каждом изменении версии Scala для кросс-сборки.

Когда я пытаюсь построить кросс publish Я использую следующую команду:

sbt ";stamp-version ;+publish"

Вот код для команды 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))
  }
}

Есть ли другой способ сохранить версию с меткой времени, к которой могут обращаться мои перекрестные сборки?

РЕДАКТИРОВАТЬ: Чтобы быть ясным, я хочу, чтобы каждая кросс-сборная версия имела одну и ту же временную метку, чтобы при ее использовании откуда-то еще я мог зависеть от этого: "x" %% "y" % "z"

Кроме того, было бы лучше, если бы решение могло работать с SBT 0.12.x, поскольку у меня все еще есть эта зависимость.

Решение

Я не уверен, рекомендуется ли подход в SBT 0.13.xНо мне показалось, что следующее сработало нормально.

Если вам нужно "иметь одинаковую временную метку" для всех версий, перечисленных в crossScalaVersionsзатем вы можете использовать генерирующие файлы, то есть методы IO.write и IO.read, чтобы сохранить файл метки времени с уникальной версией моментального снимка.

ПРИМЕЧАНИЕ Не устанавливайте scalaVersion в build.sbt так как он перезаписывает тот, который установлен +, Это была проблема в моем первоначальном ответе.

Иметь следующую задачу stampVersion в build.sbt (Я оставляю миграцию на SBT < 0,13 в качестве упражнения):

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
}

Когда вы запускаете задачу stampVersionфайл создается в target/timestamp файл.

С помощью следующего задания вы можете прочитать его содержание.

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
}

использование show getStampVersion показать версию, сохраненную в файле.

Для того, чтобы установить version ключ к версии с меткой времени, я определил команду setVersionFromStampFile (как это меняет состояние проекта).

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

С помощью команды setVersionFromStampFileвсякий раз, когда он запускается, version устанавливается соответствующим образом.

В определении сборки build.sbt, есть настройка crossScalaVersions определены, например

crossScalaVersions := Seq("2.9.3", "2.10.3")

Определите псевдоним команды setStampAsVersionAndShow в build.sbt облегчить тестирование - вы увидите значения version а также scalaVersion настройки после выполнения команды setVersionFromStampFile:

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

Это позволяет вам выполнить несколько команд:

[sbt-0-13-1]> + setStampAsVersionAndShow

определять publishTo настройка и другой псевдоним команды setStampAsVersionAndPublish в build.sbt:

publishTo := Some(Resolver.file("file", target.value / "xxx"))

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

Теперь вы должны быть в состоянии publish как и следовало ожидать:

  1. Давайте начнем заново.

  3. Проверьте это с publish без перекрестной застройки (нет +).

Мы могли бы установить DATETIME в bash так:

export DATETIME=`date +"%Y-%m-%d_%H-%M-%S"`

а затем создайте наше программное обеспечение, например

sbt 'set version in ThisBuild := s"1.0.0-${sys.env.get("DATETIME").get}"' +compile +publish

Это позаботится о том, чтобы для обеих версий компиляции использовалась одна и та же отметка времени.
