A Semantic Version Plugin for Gradle that manages a project version via a properties file, and provide tasks to automatically increase major, minor and patch build numbers.

Using the plugin

The plugin is published to the Plugin Portal; see instructions there: net.thauvin.erik.gradle.semver

Version Properties File

By default, a version.properties file will be created when Gradle is run:

#version.properties
version.major=1
version.minor=0
version.patch=0
version.preRelease=
version.buildMeta=

To change the version of your project, remove the version from your build.gradle and simply edit your the version properties file to match your version number.

If you need to change some of the property file or name of the properties key to match your own build environment. Please see the Configuration section.

Increment Version Tasks

The incrementMajor, incrementMinor and incrementPatch are available to automatically increment their respective and reset lower counterpart version numbers.

• incrementMajor will increment the major and set the minor and patch versions to 0.
• incrementMinor will increment the minor and set the path version to 0.

Examples

./gradlew incrementPatch ...

or in your gradle.build file:

someTask {
    dependsOn(incrementPatch)
    ...
}

Configuration

Version Properties

The following default properties are recognized:

Property	Description	Default
version.major	The major version.	1
version.minor	The minor version.	0
version.patch	The patch version.	0
version.preRelease	The pre-release version
version.buildMeta	The build metatdata version
version.preReleasePrefix	The pre-release prefix	-
version.buildMetaPrefix	The build metadata prefix	+

Semver Task

The semver task is used to configure how the plugin will read/write the version properties file. It most cases it is not needed.

But, for example, if you wanted to save the version properties in a different file:

semver {
    properties = "my.version" // read and save properties in "my.version"
}

or using different property keys for the version data:

semver {
    majorKey = "major" // instead of the default version.major
    minorKey = "minor"
    patchKey = "patch"
    preReleaseKey = "release"
    buildMetaKey = "metadata"
}

which would match the data in my.version:

#my.version
major=1
minor=0
patch=0
release=beta
metadata=
