Gradle Git Changelog

Gradle plugin for generating a changelog based on a Git commit history.

See recent changes.

Note: This plugin should not be considered stable until 1.0.

Usage

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.selesse:gradle-git-changelog:0.2.+'
    }
}

apply plugin: 'com.selesse.git.changelog'

Build script snippet for new, incubating, plugin mechanism introduced in Gradle 2.1 for gradle-git-changelog:

plugins {
    id 'com.selesse.git.changelog' version '0.2.+'
}

This will automatically hook the generateChangelog task into the processResources or assemble task of the project.

Configuration

All of these configurations are optional.

changelog {
    // The title appears at the top of the changelog.
    // Default value: the name of the project.
    title = "${project.name} - Changelog"

    // The output directory where the report is generated.
    // Default value: main resource directory, or the "build" directory
    outputDirectory = file("$projectDir")

    // The name of the report to generate.
    // Default value: CHANGELOG.md
    fileName = "changelog.txt"

    // The range of commits the changelog should be composed of.
    // Default value: 'beginning' (i.e. full changelog)
    // Possible values: 'beginning', 'last_tag', 'xxx'
    //
    // 'last_tag' will use all the commits since the last tag,
    // 'beginning' will use all commits since the initial commit (default)
    // 'xxx' will use all the tags since the 'xxx' Git reference (i.e. `since = 1.2.0` will display the changelog
    //       since the 1.2.0 tag, excluding 1.2.0)
    since = 'last_tag'

    // The output formats that should be generated.
    // Default value: ['markdown']
    // Possible values: 'html', 'markdown'.
    formats = ['html', 'markdown']


    // The Git "pretty" changelog commit format.
    // Default value: %ad%x09%s (%an), which produces:
    // Thu May 7 20:10:33 2015 -0400	Initial commit (Alex Selesse)
    commitFormat = '%s (%an)'

    // Specifies a commit format for Markdown.
    // Default value: '* %s (%an)', which produces:
    // * Initial commit (Alex Selesse)
    markdown {
        commitFormat = '* %s (%an)'
    }

    // Specifies a commit format for the HTML template.
    // Default value: see commitFormat
    html {
        commitFormat = '%s (%an)'

        // The Groovy HTML template used to generate the HTML changelog.
        // See http://docs.groovy-lang.org/latest/html/documentation/template-engines.html
        template = file("$projectDir/htmlTemplate").text
    }

    // A closure that returns 'true' if the line should be included in the changelog.
    // Default value: accept everything, { true }
    includeLines = {
        !it.contains("Merge")
    }

    // A closure that transforms a changelog String.
    // Default value: the identity closure, { it }
    //
    // For example, to remove '[ci skip]' from the changelog messages:
    processLines = {
        String input = it as String
        if (input.contains('[ci skip] ')) {
            input = input.minus('[ci skip] ')
        }
        input
    }
}
