👻 semver-git-plugin

Version your gradle projects with git tags and semantic versioning.

Apply the plugin

Gradle 2.1 and higher

plugins {
    id("io.wusa.semver-git-plugin").version("2.3.7")
}

Gradle 1.x and 2.0

buildscript {
   repositories {
      maven {
         url "https://plugins.gradle.org/m2/"
       }
   }
   dependencies {
      classpath 'io.wusa:semver-git-plugin:2.3.7'
   }
}

apply plugin: 'io.wusa.semver-git-plugin'

Configure the plugin

semver {
    snapshotSuffix = "SNAPSHOT" // (default) appended if the commit is without a release tag
    dirtyMarker = "dirty" // (default) appended if the are uncommitted changes
    initialVersion = "0.1.0" // (default) initial version in semantic versioning
    tagPrefix = "" // (default) each project can have its own tags identified by a unique prefix.
    tagtype = TagType.Annotated // (default) options are Annotated or Lightweight
    branches { // list of branch configurations
        branch {
            regex = ".+" // regex for the branch you want to configure, put this one last
            incrementer = "NO_VERSION_INCREMENTER" // (default) version incrementer
            formatter = { "${semver.info.version.major}.${semver.info.version.minor}.${semver.info.version.patch}+build.${semver.info.count}.sha.${semver.info.shortCommit}" } // (default) version formatting closure
        }
    }
}

Use with a Gradle multi-module project

For projects which take advantage of Gradle's multi-module projects, it is possible to specify different tags for each module.

The tags for each module must be distinguished with an unambiguous prefix. For example, if you have three modules foo, bar, and blega, you may consider using the module name as the prefix. This prefix is configured in the semver configuration block:

semver {
  tagPrefix = "foo-"
}

Given the above configuration, the tags for the "foo" module must all begin with "foo-"; e.g., "foo-3.2.6", etc... Note that besides the prefix, the rules for the tag names must still follow all the same semver rules as apply in any other case.

Incrementer

Incrementer	Description
NO_VERSION_INCREMENTER	Doesn't increment the version at all.
PATCH_INCREMENTER	Increments the patch version by one.
MINOR_INCREMENTER	Increments the minor version by one.
MAJOR_INCREMENTER	Increments the major version by one.
CONVENTIONAL_COMMITS_INCREMENTER	Increments the version according to conventional commits.

Release

The versions have to be stored as annotated or lightweight (depending on the configured tag type) git tags in the format of semantic versioning.

To create a new annotated release tag:

git tag -a 1.0.0-alpha.1 -m "new alpha release of version 1.0.0"
git push --tags

To create a new lightweight release tag:

git tag -a 1.0.0-alpha.1
git push --tags

Following commits without a release tag will have the snapshotSuffix (default SNAPSHOT) appended and the version number bumped according to incrementer (default minor) strategy, e.g., 1.1.0-alpha.1-SNAPSHOT.

Version usage

Then you can access the version of your project via semver.info.

Examples:

allprojects {
    version = semver.info
}

project.version = semver.info

Version information

semver.info

Access the following information via semver.info.* e.g., semver.info.tag.

Property	Description	Git: master	Git: feature/ghosty
info.branch.group	Group of the branch	master	feature
info.branch.name	Name of the branch	master	feature/ghosty
info.branch.id	Tokenized branch name	master	feature-ghosty
info.commit	Full sha1 commit hash	4ecabe2e8646fd0b577dcda83e5c23447e230496	4ecabe2e8646fd0b577dcda83e5c23447e230496
info.shortCommit	Short sha1 commit has	d2459d	d2459d
info.tag	Current tag	If any name of the tag else none	If any name of the tag else none
info.lastTag	Last tag	If any name of the tag else none	If any name of the tag else none
info.dirty	Current state of the working copy	true if the working copy contains uncommitted files	true if the working copy contains uncommitted files
info	Formatted version	0.1.0	0.1.0
info.version.major	Major version of 2.0.0-rc.1+build.123	2	2
info.version.minor	Minor version of 2.0.0-rc.1+build.123	0	0
info.version.patch	Patch version of 2.0.0-rc.1+build.123	0	0
info.version.build	Build number of 2.0.0-rc.1+build.123	build.123	build.123
info.version.prerelease	Pre release of 2.0.0-rc.1+build.123	rc.1	rc.1

Display version

The semver.info is based on the current or last tag (depending on the specified tag type).

• If the current commit has an tag this tag will be the version.
• If the current commit has no tag the version takes the last tag and builds the new version based on:
  • The ordering of the branch configuration is important for the matching.
• If no tag exists the initial commit will be version 0.1.0 as recommended by Semantic Versioning 2.0.0. The following commits will be build based on this version until a tag is created.
