Kewt versioning Gradle plugin

inspired by Axion release plugin

Project versioning using Git tags with type safe Gradle Kotlin DSL.

Quick start

Kotlin

build.gradle.kts

plugins {
    id("com.github.mfarsikov.kewt-versioning") version "1.0.0"
}
version = kewtVersioning.version

Tasks

• currentVersion prints current version.

Configuration

This is default configuration. It includes two pre-configured branches: master and all other (.*). Order does matter. First matched config will be used.

Kotlin

`build.gradle.kts`:

import com.github.mfarsikov.kewt.versioning.plugin.Incrementer

kewtVersioning.configuration {
    gitPath = project.rootDir  // default
    prefix = "v-" // default
    remoteName = "origin" // default
    userName = "\${GITHUB_USER_NAME}" // default
    password = "\${GITHUB_PASSWORD}" // default
    versioning = SEMANTIC // default, can be INCREMENTAL
    branches {
        add {
            regexes = mutableListOf("master".toRegex())
            incrementer = Incrementer.MINOR // default
            stringify = stringifier(
                useBranch = false,  // by default: true
                useSnapshot = true, // default
                useDirty = true, // default
                useSha = false,  // by default: null
                useTimestamp = false, // by default: null
                timeZone = ZoneOffset.systemDefault() // Default
            )
        }
        add {
            regexes = mutableListOf(".*".toRegex())
            stringify = stringifier(
                useTimestamp = false,
                useSha = false
            )
        }
    }
}

• gitPath - path to .git folder. Default is project root gitPath=project.rootDir.
• prefix - is used for Git tags. By default prefix="v-". Tags look like this: v-0.0.1. Submodules can use different tags to have independent versioning.
• remoteName remote repository name. Default is "origin". To prevent pushing tags to remote could be reset to null
• userName and password used for HTTPS connection to remote repository. If value has prefix ${ and postfix } (string in Kotlin "\${MY_PWD}") it will be resolved from environment variables. Could contain plain values (highly not recommended).
• versioning - could be one of [SEMANTIC | INCREMENTAL]. Semantic uses 3 digit version (v-1.2.3) whereas incremental only one (v-1)
• branches - per branch configuration. By default, this list has two configurations: first matches master (or main) branch, the second matches rest of branches.
  • regexes - list of regexes for branch names. Default is mutableListOf("master".toRegex(), "main".toRegex()). Hint: to avoid a lot of escape symbols use triple double-quotes in Kotlin
  • incrementer - default incrementer for the matched branch. Default value is Incrementer.Minor. Could be Major, Minor, Patch. Each branch could have its own default version increment strategy. Master and feature branches could increment their minor versions (0.1.0 -> 0.2.0). Release and fix branches could increment patch versions (0.1.0 -> 0.1.1)
  • stringify - version string configuration. Version name could include branch name, snapshot sign, dirty sign, commit SHA signature and timestamp. There is a builder smartVersionStringifier(useBranch, useSnapshot, useDirty, useSha, useTimestamp, timeZone), but if it is not enough the stringify property is of (DetailedVersion) -> String type, so implementation could be provided in place. Like:

  stringify = { version: DetailedVersion -> "here-could-be-your-prefix-${version.sha}"}

Stringifier

This function is responsible for creating string version generator, that will be used in gradle script.

Parameters:

• useBranch if true (default) version includes branch name
• useSnapshot if true (default) and current commit is not tagged by version tag, then version includes -SNAPSHOT suffix
• useDirty if true (default) and there are uncommitted changes, then version includes -dirty suffix
• useSha if null (default) version includes commit SHA if it is a snapshot. If true version always includes commit SHA
• useTimestamp if null (default) version includes timestamp if it is dirty. If true version always includes timestamp
• timeZone time zone used in timestamp. Default value is UTC.

Examples for configurations and output

(SHA is shortened for brevity)

	Released (the tag is present on current commit)	Snapshot (current commit is ahead of tag)	Dirty (uncommitted changes)
default	0.4.0-master	0.4.0-master-SNAPSHOT-dbef6a	0.4.0-master-SNAPSHOT-dbef6a-dirty-2020-05-16T20-34-46.771
useBranch = false	0.4.0	0.4.0-SNAPSHOT-dbef6a	0.4.0-SNAPSHOT-dbef6a-dirty-2020-05-16T20-34-46.771
useSnapshot = false	0.4.0-master	0.4.0-master-dbef6a	0.4.0-master-dbef6a-dirty-2020-05-16T20-34-46.771
useDirty = false	0.4.0-master	0.4.0-master-SNAPSHOT-dbef6a	0.4.0-master-SNAPSHOT-dbef6a-2020-05-16T20-34-46.771
useSha = true	0.4.0-master-dbef6a	0.4.0-master-SNAPSHOT-dbef6a	0.4.0-master-SNAPSHOT-dbef6a-2020-05-16T20-34-46.771
useTimestamp = true	0.4.0-master-2020-05-16T20-34-46.771	0.4.0-master-SNAPSHOT-dbef6a-2020-05-16T20-34-46.771	0.4.0-master-SNAPSHOT-dbef6a-2020-05-16T20-34-46.771
useTimestamp = false, useSha = false	0.4.0-master	0.4.0-master-SNAPSHOT	0.4.0-master-SNAPSHOT-dirty

Incremental versioning

If there is no need to use complex major/minor/patch semantic versioning, INCREMENTAL versioning can be configured. In this case version consist of a single number, and it is treated as major one.

Usage example

• Kewt versioning plugin is versioned by kewt versioning plugin (see build.gradle.kts)
• Using in multiproject build: https://github.com/mfarsikov/kewt
• https://github.com/mfarsikov/kotlite
• https://github.com/mfarsikov/kotgres
