Gradle Git Versioning Plugin Sparkline

Gradle Plugin Portal Changelog Build Workflow LGTM Grade

ℹ Also available as Maven Extension

Example

This plugin can virtually set project version and properties, based on current Git status.

No files will be modified, version and properties are modified in memory only.

  • Get rid of...
    • editing build.gradle
    • managing project versions within files and Git tags
    • git merge conflicts

Usage

Add Plugin to Gradle Project

⚠️ Minimum required Java version 11

⚠️ You should apply git versioning (gitVersioning.apply{...}) directly after version declaration at root project only.

Groovy DSL build.gradle

plugins {
    id 'me.qoomon.git-versioning' version '6.4.4'
}

version = '0.0.0-SNAPSHOT'
gitVersioning.apply {
    // see configuration documentation below
}

Kotlin DSL build.gradle.kts

plugins {
    id("me.qoomon.git-versioning") version "6.4.4"
}

version = "0.0.0-SNAPSHOT"
gitVersioning.apply {
    // see configuration documentation below
}

Configure Plugin

ℹ Consider CI/CD section when running this plugin in a CI/CD environment

You can configure the version and properties adjustments for specific branches and tags.

Groovy DSL Example: build.gradle

version = '0.0.0-SNAPSHOT'
gitVersioning.apply {
    refs {
        branch('.+') {
            version = '${ref}-SNAPSHOT'
        }
        tag('v(?<version>.*)') {
            version = '${ref.version}'
        }
    }

    // optional fallback configuration in case of no matching ref configuration
    rev {
        version = '${commit}'
    }
}

Kotlin DSL Example: build.gradle.kts

version = "0.0.0-SNAPSHOT"
gitVersioning.apply {
    refs {
        branch(".+") {
            version = "\${ref}-SNAPSHOT"
        }
        tag("v(?<version>.*)") {
            version = "\${ref.version}"
        }
    }

    // optional fallback configuration in case of no matching ref configuration
    rev {
        version = "\${commit}"
    }
}

Configuration Options

  • disable global disable(true)/enable(false) extension, default is false.

    • Can be overridden by command option, see (Parameters & Environment Variables)[#parameters-&-environment-variables]
  • describeTagPattern An arbitrary regex to match tag names for git describe command

    • has to be a full match pattern e.g. v(.+), default is .*
  • describeTagFirstParent Enable(true) or disable(false) following only the first parent in a merge commit

    • default is true
  • updateGradleProperties Enable(true)/disable(false) version and properties update in gradle.properties file, default is false

    • Can be overridden by command option, see (Parameters & Environment Variables)[#parameters-&-environment-variables]
  • refs List of ref configurations, ordered by priority.

    • ℹ First matching configuration will be used.

    • considerTagsOnBranches By default, tags pointing at current commit will be ignored if HEAD is attached to a branch.

      • If this option is true tags will always be taken into account.

    • branch(pattern)/tag(pattern) specific ref patch definition.

      • pattern An arbitrary regex to match ref names

        • has to be a full match pattern e.g. main or feature/.+

      • describeTagPattern An arbitrary regex to match tag names for git describe command

        • has to be a full match pattern e.g. v.+)
        • will override global describeTagPattern value
      • describeTagFirstParent Enable(true) or disable(false) following only the first parent in a merge commit

        • default is true

      • version The new version format, see Format Placeholders

      • properties A property definitions to update the value of a property.

        • name The property name
        • value The new value format of the property, see Format Placeholders

          groovy
          properties = [
            "name" : "value",
          ]
          ⚠️ groovy.lang.MetaClass hides properties config field.
          If you need to call a method on properties config field, you need to use the alias field properties_ e.g. properties_.put("name", "value")

          kotlin
          properties = mapOf(
            "name" to "value",
          )            

      • updateGradleProperties Enable(true) or disable(false) version and properties update in gradle.properties file

        • will override global updateGradleProperties value
  • rev Rev configuration will be used if no ref configuration is matching current git situation.

    • same as branch(pattern)/tag(pattern) configuration, except pattern parameter.

Format Placeholders

….slug placeholders means all / characters will be replaced by -.

ℹ Final version will be slugified automatically, so no need to use ${….slug} placeholders in version format.

ℹ define placeholder default value (placeholder is not defined) like this ${name:-DEFAULT_VALUE}
e.g ${env.BUILD_NUMBER:-0} or ${env.BUILD_NUMBER:-local}

ℹ define placeholder overwrite value (placeholder is defined) like this ${name:+OVERWRITE_VALUE}
e.g ${dirty:-SNAPSHOT} resolves to -SNAPSHOT instead of -DIRTY

CI/CD Setup

Most CI/CD systems do checkouts in a detached HEAD state so no branch information is available, however they provide environment variables with this information. You can provide those, by using Parameters & Environment Variables.

Native Support

  • GitHub Actions: if $GITHUB_ACTIONS == true, GITHUB_REF is considered
  • GitLab CI: if $GITLAB_CI == true, CI_COMMIT_BRANCH, CI_COMMIT_TAG and CI_MERGE_REQUEST_SOURCE_BRANCH_NAME are considered
  • Circle CI: if $CIRCLECI == true, CIRCLE_BRANCH and CIRCLE_TAG are considered
  • Jenkins: if JENKINS_HOME is set, BRANCH_NAME and TAG_NAME are considered

Manual Setup

Set following environment variables before running your gradle command

export VERSIONING_GIT_REF=$PROVIDED_REF;

$PROVIDED_REF value examples: refs/heads/main, refs/tags/v1.0.0 or refs/pull/1000/head

or

export VERSIONING_GIT_BRANCH=$PROVIDED_BRANCH;
export VERSIONING_GIT_TAG=$PROVIDED_TAG;

$PROVIDED_BRANCH value examples: main, refs/heads/main or refs/pull/1000/head

$PROVIDED_TAG value examples: v1.0.0 or refs/tags/v1.0.0
