Welcome to XebiaLabs Community Plugins

This page describes how you can contribute to the XebiaLabs community plugins, where the continuous integration is located and what steps to follow to release your community plugin.

To join the xebialabs-community organization, create a GitHub account and request to join the organization by sending an email to rbroker@xebialabs.com and amohleji@xebialabs.com.

Quickstart for Existing Plugins

If you want to contribute to an existing repository, simply fork the repository, make your changes, and send a pull request. If you need help with this, contact an existing plugin contributor - for example the person who last committed to that repository.

Plugin Setup

License

XebiaLabs requires that each plugin use the MIT license:

Copyright <YEAR> <COPYRIGHT HOLDER>

Licensing can be easily handled using the Gradle license plugin:

plugins {
    id "com.github.hierynomus.license" version "0.13.1"
}
...
license {
  header rootProject.file('License.md')
  strictCheck false
  ext.year = Calendar.getInstance().get(Calendar.YEAR)
  ext.name = 'DIGITAL.AI'
}

Dependencies

We have a public artifact repository which Gradle or Maven can use to fetch dependencies. It is located at https://dist.xebialabs.com/public/maven2. A Gradle configuration which uses the repository would look like this:

repositories {
  ...
  maven {
    url 'http://dist.xebialabs.com/public/maven2'
  }
}

Continuous Integration

Travis CI

XebiaLabs uses Travis CI for continuous integration. Go to Travis CI and log in with your GitHub account. After you log in, you'll see the community plugins being built. The build configuration is provided by the .travis.yml file in each repository. More information is available at the Travis CI documentation site.

When creating the .travis.yml file, please configure Slack notifications as described here and GitHub releases as described here. Use the XebiaLabsCommunityCI system account for GitHub keys.

Circle CI

As an alternative, you can use Circle CI.

Gradle Wrapper

Using a Gradle wrapper ensures that the same Gradle version is used for all builds (including on Travis CI). An example Gradle wrapper can be found in the xld-openshift-plugin repository. You can copy the example wrapper or create one yourself using gradle wrapper.

Builds should typically be ran with ./gradlew build.

Release Outline

Versioning - Manual/Basic

• Update the build.gradle file to contain the new version number.
• Update the .travis.yml file to contain the new version number.
• Create a new tag, using semantic versioning.
  • For example: git tag -a v4.5.2 -m 'Version 4.5.2' 373159 for commit 373159.
• Push the tag to GitHub: git push --follow-tags.

Versioning - Nebula and Travis

Nebula eliminates the need to set and/or change the version number in the Gradle file. The Travis build will use the version number set in the commit tag. The tags in the repository must be set appropriately by the developer for a major, minor, or patch release using the Nebula conventions.

Gradle Config

• Add id 'nebula.release' version '6.0.0' to the plugins section of the build.gradle file.
• Remove the hard-coded version assignment if present.
• Add scope and useLastTag logic. Note, if it appears that Gradle is not processing these lines, move them higher in the build.gradle file. See the history of the build.gradle file in https://github.com/xebialabs-community/xlr-ansible-tower-plugin for an example.

if (!project.hasProperty('release.scope')) {
  project.ext['release.scope'] = 'patch'
}
if (!project.hasProperty('release.useLastTag')) {
  project.ext['release.useLastTag'] = true
}

Nebula Compatibility of Existing Tags

Check that existing tags meet Nebula conventions. The tag format should be vx.y.z, where x = major release number, y = minor release number, z = patch level. See the Semantic Versioning reference at https://semver.org.

Travis Config

Edit the .travis.yml file:

• The Travis gem can be installed with gem install -v 1.7.5 --no-rdoc --no-ri travis.

• If the api_key credentials are not working, generate new ones with travis setup releases --force and the XebiaLabsCommunityCI system account.

• Add file_glob: true to allow wildcards in the file: argument(s).

• Set or change file to build/distributions/* or build/libs/*. The argument can point to a single file (with or without wildcards) or list of files in yml notation.

• Add skip_cleanup: true, so the cleanup doesn't delete the file to be uploaded.

• Add on: block
  all_branches: true
tags: true
repo: repo-owner/repo-name

• Also, before_deploy: and after_deploy: blocks are available to run scripts before/after release is pushed.

• Turn on the switch for the repository at https://travis-ci.org/profile/xebialabs-community.

Example:

deploy:
  provider:  releases
  api_key:
    secure:  ...
  file_glob:  true
  file:  build/distributions/*
  skip_cleanup:  true
  on:
    all_branches:  true
    tags:  true
    repo:  repo-owner/repo-name

New Releases

• Add id 'nebula.release' version '6.0.0' to plugins.
• Remove the hardcoded version assignment if present.
• Add scope and useLastTag logic. Note, if it appears that Gradle is not processing these lines, move them higher in the build.gradle file. See the history of the build.gradle file in https://github.com/xebialabs-community/xlr-ansible-tower-plugin for an example.

if (!project.hasProperty('release.scope')) {
  project.ext['release.scope'] = 'patch'
}
if (!project.hasProperty('release.useLastTag')) {
  project.ext['release.useLastTag'] = true
}

• Confirm a successful build in your local directory.
• Commit the code changes in your local directory, then push them to the GitHub repository.
• Set the appropriate tag, e.g., git tag -a "v1.3.0" -m "Version 1.3.0" for the last commit.
• Execute git push --follow-tags.
• Each push will trigger a Travis job; the second job will add the files listed to the repository's Releases page.
• Consider editing the release notes in GitHub to provide better insight into what's included/important for this release.

Definition of Done

• Each repository must include the MIT license.
• Each repository must have a description.
• Each repository must have one or more GitHub topics defined.
• If your repository is a plugin, the repository name should end with plugin.
• If your repository is a plugin for XL Deploy, the repository name should start with xld.
• If your repository is a plugin for XL Release, the repository name should start with xlr.
• Each repository must have public CI enabled (Travis, CircleCI, or other) and the corresponding badge in the README.md file.
