sbt-git and sbt-native-packager

[magegu]

hi guys,

for easier distribution and testing I would like to see the git commit SHA added to the debian version string. I added the sbt-git plugin but the deb version keeps untouched while the play:dist task builds a git-versioned zip file (so i assume the plugin itself is working). To push new deb archives i'll now have to change the version number which is a bit annoying for continues systems.

You could add date or timestamp to version in build definition e.g.

val appVersion = "0.2" + System.currentTimeMilis().toString

I've done it like this in build.sbt (without sbt-git):

version := "0.2-SNAPSHOT"

// If the version ends with "-SNAPSHOT", let the Debian version end with
// "~SNAPSHOT~yyyyMMddHHmmss". This way updates of the snapshot version can be
// detected by the package manager. Also the tilde "~" sorts before anything
// else when comparing version numbers. This way "1.0" will be regarded newer
// than "1.0~beta".
version in Debian <<= (version) { (v) =>
    if (v.endsWith("-SNAPSHOT")) {
       val timestampFormat = new java.text.SimpleDateFormat("yyyyMMddHHmmss");
       timestampFormat.setTimeZone(java.util.TimeZone.getTimeZone("UTC"));
       val now = timestampFormat.format(new java.util.Date());
       v.replace("-SNAPSHOT", "~SNAPSHOT~" + now)
    } else {
       v
    }
}

Thanks for sharing. If you figure out a way with sbt-git let me know. This would be even better.

I’ve tried it with sbt-native-packager 0.7.0-M2 and sbt-git 0.6.2 and for me it just works as advertised? I’ve put this in my build.sbt according to the instructions:

import com.typesafe.sbt.SbtGit._

versionWithGit

git.baseVersion := "0.1"

If the head revision is not tagged the commit hash is appended to the version of the .deb, too. If it is tagged the version from the tag is used.

I can reproduce what @hfs did. Take care that you don't have any version := "x.y" settings in your build.sbt
