将时间戳添加到由 sbt-native-packager 创建的 zip

Question

是否可以在执行 dist 命令时获得的生成的 zip 文件名中附加时间戳？

假设我的项目名称是"backend"，当前的开发版本是0.2.3-SNAPSHOT。我想做的是执行 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

Answer 1

 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
 }

下面是 dist 对 version := "1.0-SNAPSHOT" 和 version := "1.0" 所做的（去除一些噪音）：

 [play-scala] $ dist

请注意，jar 文件名不受影响。
