conventional-commits-plugin

Introduction

This plugin can be used to determine the next release version based on previous tags and the commit messages used.
It can also be used to get the current version. ⚠️ By default only annotated tag are supported, to support non annotated tag you must use an option to activate this feature (see below).⚠️ It calculates the version number based on the format of the commit message.
The commit message format used is conventional commits.

Getting started

This plugin can be used in a pipeline in a stage or the environment block. Some examples of this in use are:

In the environment block

pipeline {
    agent any

    environment {
        CURRENT_VERSION = currentVersion()
        NEXT_VERSION = nextVersion()
    }

    stages {
        stage('Hello') {
            steps {
                echo "current vesion = ${CURRENT_VERSION}"
                echo "next version = ${NEXT_VERSION}"
            }
        }
    }
}

In a scripted Pipeline

def NEXT_VERSION
node {
    stage('Get next version ...') {
      CURRENT_VERSION=currentVersion()
      echo "Current version: $CURRENT_VERSION"  
      NEXT_VERSION=nextVersion()
      echo "Next version : $NEXT_VERSION"
    }
    stage ('Release') {
        sh "mvn release:prepare -DreleaseVersion=$NEXT_VERSION"
        sh 'mvn release:perform'
    }
}

Using Optional Parameters

The plugin provides provision to use optional parameters for support of build metadata, pre-release information, settings the start tag, etc. ⚠️ These parameters are only for the nextVersion step ! ⚠️

Build Metadata

buildMetadata an optional parameter can be added as follows:

pipeline {
    agent any
    environment {
        NEXT_VERSION = nextVersion(buildMetadata: "$env.BUILD_NUMBER")
    }
    stages {
        stage('Hello') {
            steps {
                echo "next version = ${NEXT_VERSION}"
            }
        }
    }
}

Assuming next version is 1.1.0. The pipeline will output :next version = 1.1.0+001

Use with prerelease information

For a 1.0.0 existing version the following code :

pipeline {
    agent any

    environment {
        NEXT_VERSION = nextVersion(preRelease: 'alpha')
    }

    stages {
        stage('Hello') {
            steps {
                echo "next version = ${NEXT_VERSION}"
            }
        }
    }
}

Will display :next version = 1.1.0-alpha

Prerelease possible combinations

There are three options to manipulate the prerelease option :

the name of the prerelease ➡️ preRelease
keep the existing prerelease (default false) ➡️ preservePrelease
increment the existing prerelease (default false) ➡️ incrementPreRelease

The table below resume the combined use of these options and the result:

current version	Breaking change commit msg	Feature commit msg	Other or empty commit msg	prerelease	preservePreRelease	incrementPreRelease	Output
0.1.0	X	-	-	-	-	-	1.0.0
0.1.0	-	X	-	-	-	-	0.2.0
0.1.0	-	-	X	-	-	-	0.1.1
0.1.0	X	-	-	alpha	-	-	1.0.0-alpha
0.1.0	-	X	-	alpha	-	-	0.2.0-alpha
0.1.0	-	-	X	alpha	-	-	0.1.1-alpha
1.0.0-alpha	-	-	-	-	-	-	1.0.0
0.1.0-alpha	-	-	-	-	-	-	0.1.0
0.1.1-alpha	-	-	-	-	-	-	0.1.1
0.1.0-alpha	X	-	-	-	X	-	1.0.0-alpha
0.1.0-alpha	-	X	-	-	X	-	0.2.0-alpha
0.1.0-alpha	-	-	X	-	X	-	0.1.1-alpha
0.1.0-alpha	-	-	X	-	X	X	0.1.1-alpha.1
0.1.0-alpha	X	-	-	beta	-	-	1.0.0-beta
0.1.0-alpha	-	X	-	beta	-	-	0.2.0-beta
0.1.0-alpha	-	-	X	beta	-	-	0.1.1-beta

Write next version in the configuration file (pom.xml, package.json)

The optional parameter writeVersion allow writing back to the file the next calculated version.

⚠️ For some configurations files, the CLI is needed (maven fo example). ⚠️

The supported configurations files :

pom.xml (Maven) : need the Maven CLI in the path,
package.json (NPM) : need the Npm CLI in the path,
chart.yaml (Helm),
build.gradle / gradle.properties (Gradle),
setup.py / setup.cfg / pyproject.toml (Python),
go.mod (GoLang).

Example of use : With a project with a package.json as follows :

{
  "name": "conventional-commits-plugin-example-npm",
  "version": "1.0.0",
  "description": "Npm example project"
}

The following pipeline with a commit with a commit message like feat: my cool feature:

pipeline {
    agent any
    environment {
        NEXT_VERSION = nextVersion(writeVersion: true)
    }
    stages {
        stage('Hello') {
            steps {
                echo "next version = ${NEXT_VERSION}"
            }
        }
    }
}

Will update the package.json as follows :

{
  "name": "conventional-commits-plugin-example-npm",
  "version": "1.1.0",
  "description": "Npm example project"
}
