在SBT中交叉構建時設置唯一的快照版本

當publish時，如果版本中有-SNAPSHOT，我想用唯一的時間戳替換它。我已經完成了這個工作，除了與+交叉構建外，它已經可以工作了。在SBT中交叉構建時設置唯一的快照版本

似乎我設置的時間戳記的設置version會在跨版本更改時更改爲Scala版本。

當我嘗試跨打造publish我使用下面的命令：

sbt ";stamp-version ;+publish"

下面是命令stamp-version代碼：

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)) 
    } 
}

是否有不同的方法，我可以存儲我可以通過交叉構建訪問的時間戳版本？

編輯：要清楚，我希望每個交叉構建版具有相同的時間戳，這樣，當我使用它從別的地方我可以依靠這樣的："x" %% "y" % "z"

而且，這將是最好的，如果該解決方案可以與SBT 0.12.x一起工作，因爲我仍然有這種依賴關係。

我不確定這是SBT 0.13.x中的推薦方法，但下面的方法似乎對我來說工作得很好。

如果需要「具有相同的時間戳」在crossScalaVersions列出的所有版本，那麼你可能想利用Generating files，即IO.write和IO.read方法，保存時間戳文件具有獨特的快照版本。

注意不要設置在build.sbtscalaVersion，因爲它會覆蓋一個由+設置。這是我最初的答案中的問題。

有以下任務build.sbtstampVersion（我把它遷移到SBT < 0.13作爲練習）：

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 
}

當您運行任務stampVersion，文件獲取target/timestamp文件中創建。

通過以下任務，您可以閱讀其內容。

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顯示保存在文件中的版本。

爲了version鍵設定爲時間戳的版本，我定義的命令setVersionFromStampFile（因爲它改變一個項目的狀態）。

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

隨着命令setVersionFromStampFile，一旦進入運行，version得到適當設置。

[sbt-0-13-1]> show version

在構建定義build.sbt，已經設定crossScalaVersions限定，例如

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

定義命令別名setStampAsVersionAndShow在build.sbt緩解測試 - 你會看到的version和scalaVersion設置的值在執行命令後setVersionFromStampFile：

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

這使您可以跨執行一系列命令：

定義publishTo設置和一個其他命令別名setStampAsVersionAndPublish在build.sbt：

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

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

您現在應該能夠publish如你所期望：

感謝亞採。我更新了我應該更具體的問題。這個解決方案看起來好像每個版本的Scala都有不同的時間戳組件，它們是交叉構建的，這對我來說並不是那麼有用，因爲它很難依賴於它。 – myyk

@myyk答案已經改變，以反映要求。在回答你的問題時（和掌握SBT）一樣有趣。 –

感謝迄今爲止的一切，這是非常有用的，當我完成後我會分享我的0.12自適應。雖然你的解決方案有問題，但我也一樣，它也在上面的輸出中。設置到版本2.9.3後，你可以看到它發佈到sbt-0-13-1_2.10這是錯誤的，它應該是sbt-0-13-1_2.9.3。 – myyk
