A Gradle Plugin which adds tasks to support the Gitflow Workflow.

JGitflow Gradle Plugin

Overview

This is a Gradle Plugin which adds tasks to Gradle to support the Gitflow Workflow. The Gitflow Workflow provides a robust framework for managing larger projects. The Plugin uses org.eclipse.jgit and external.atlassian.jgitflow:jgit-flow-core to implement the Gitflow Workflow. The project is inspired by the JGitFlow Maven Plugin.
The Plugin adds the task group jgitflow which contains the following tasks:

• initJGitflow: Initializes the JGitflow context. Creates a develop branch and switches to develop branch.

• releaseStart: Creates a release branch release/<releaseVersion> from a develop branch and updates the gradle.properties file with a release version. Switches to release branch.

• releaseFinish: Merges a release branch back into the master branch and develop branch. Tags the release. Removes the release branch. Pushes everything to the remote origin. Switches back to develop branch.

• releasePublish: Publishes a release branch to the remote origin.

• featureStart: Creates a feature branch feature/<featureName> from a develop branch. Switches to feature branch.

• featureFinish: Merges a feature branch back into the develop branch. Removes the feature branch. Switches back to develop branch.

• featurePublish: Publishes a feature branch to the remote origin.

• hotfixStart: Creates a hotfix branch hotfix/<hotfixName> from a master branch. Switches to hotfix branch.

• hotfixFinish: Merges a hotfix branch back into the master branch and develop branch. Additionally the master merge is tagged with the hotfix version. Switches back to develop branch.

• hotfixPublish: Publishes a hotfix branch to the remote origin.

The project requires at least JDK 7. The project eats its own dog food.

Usage Guide

Add the following snippet to your Gradle build file:

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'io.github.robwin:jgitflow-gradle-plugin:0.3.1'
    }
}

apply plugin: 'io.github.robwin.jgitflow'

JGitflow context configuration

The default jgitflow context configuration looks as follows:

Table 1. Branch names

Logical branch name	Real branch name
master	"master"
develop	"develop"
feature	"feature/<featureName>"
release	"release/<releaseVersion>"
hotfix	"hotfix/<hotfixName>";

By default a release tag has no version prefix.

Initializes the JGitflow context

Before you can use the tasks, you must initialize the JGitflow context.

gradlew initJGitflow

If you want to change the JGitflow context configuration, you can do the following.

initJGitflow{
    feature = "features/"
    release = "releases/"
    versiontag = 'v'
}

Git authentication

If you want to push changes to a remote origin, you must specify your username and password in a ~/.gradle/gradle.properties file or as a command line parameter.
SSH is not supported yet.

Example

gitUsername=<username>
gitPassword=<password>

or

-PgitUsername=<username> -PgitPassword=<password>

Release Start Task

The task exposes a few properties as part of its configuration.

Table 2. Properties of releaseStart

Mandatory	Property	Description	Type	Default
Yes	releaseVersion	The version of the release	String	empty
No	allowSnapshotDependencies	Allow snapshot library dependencies	Boolean	false
No	baseCommit	You can optionally supply a base commit sha-1 hash to start the release from. The commit must be on the develop branch.	String	empty

Example

The tasks should be invoked via a command line.

gradlew releaseStart -PreleaseVersion=1.0.0

Release Finish Task

Table 3. Properties of releaseFinish

Mandatory	Property	Description	Type	Default
Yes	releaseVersion	The version of the release	String	empty
Yes	newVersion	The new version of the develop branch	String	empty

Example

The tasks should be invoked via a command line.

gradlew releaseFinish -PreleaseVersion=1.0.0 -PnewVersion=1.0.1-SNAPSHOT
