Question

是否可以在执行dist命令时为生成的zip文件名附加时间戳？

假设我的项目名称是“后端”，当前的开发版本是0.2.3-SNAPSHOT。我想要做的是执行dist命令并获取一个名为backend-0.2.3-SNAPSHOT-20150506.zip的文件。但是，我只想在快照版本上执行dist时附加时间戳，而不是生产版本（例如0.2.3）。

我正在使用Play 2.4.0-RC1和sbt 0.13.8

 import com.typesafe.sbt.packager.Keys._

 packageName in Universal := {
   val name = (packageName in Universal).value
   def timestamp = new java.text.SimpleDateFormat("yyyyMMdd") format new java.util.Date()
   if (isSnapshot.value) s"$name-$timestamp" else name
 }

以下是dist对version := "1.0-SNAPSHOT"和version := "1.0"的影响（消除了一些噪音）：

 [play-scala] $ dist

请注意，jar文件名不受影响。

将时间戳添加到由sbt-native-packager创建的zip
