Versioning

A Grade plugin that makes versioning easier:

android {
  defaultConfig {
    versionCode versioning.versionCode() // e.g. 42
    versionName versioning.versionName() // e.g. 1.0.0
  }
}

The only prerequisite is using Git as your VCS.

How to use it

Build script snippet for plugins DSL for Gradle 2.1 and later:

plugins {
  id "me.tadej.versioning" version "0.2.0"
}

Build script snippet for use in older Gradle versions or where dynamic configuration is required:

buildscript {
  repositories {
    maven {
      url "https://plugins.gradle.org/m2/"
    }
  }
  dependencies {
    classpath "gradle.plugin.me.tadej:versioning:0.2.0"
  }
}

apply plugin: "me.tadej.versioning"

How does it work?

The plugin assumes you use tags to mark your releases. The version name corresponds to the git command:

$ git describe --tags --dirty --always

The version code is simply the number of commits:

$ git rev-list --count HEAD

Examples

Assume you're executing the commands below in sequential order.

$ git commit -a -m "First commit."

Op	Result
versioning.versionCode()	1
versioning.versionName()	"3db5953"

$ git tag -a 0.1.0 -m "First tag."

Op	Result
versioning.versionCode()	1
versioning.versionName()	"0.1.0"

$ git commit -a -m "Second commit."

Op	Result
versioning.versionCode()	2
versioning.versionName()	"0.1.0-1-g3db5953"

$ echo "Hi, mom!" > hi.txt && git add hi.txt

Op	Result
versioning.versionCode()	2
versioning.versionName()	"0.1.0-1-g3db5953-dirty"

$ git commit -m "Third commit."

Op	Result
versioning.versionCode()	3
versioning.versionName()	"0.1.0-2-g3cbf60f"

$ git tag 0.1.1

Op	Result
versioning.versionCode()	3
versioning.versionName()	"0.1.1"

Decorators

You can tweak the version name and/or version code:

versioning {
  decorateVersionCode { code -> code * 1000 }
  decorateVersionName { name -> "$name-SNAPSHOT" }
}
