Contribute

Great you want to contribute!

It’s really simple. Well. There are some rules that you should follow:

Documentation

The process is mostly automated and convenient.

Code

  • Make sure you are following the code style below.
  • Make sure your feature is well tested.
  • Make sure your feature is well documented (Javadoc).
  • Make sure there is documentation for your feature at ninja-core/src/site/markdown.
  • Make sure your feature runs inside ninja-integration-test or ninja-servlet-jpa-blog-integration-test if you wrote a feature related to JPA.
  • Add your changes to changelog.md and your name to team.md.

Sign the contributor agreement (electronically) and send us a pull request to become a happy member of the Ninja family :)

Code style

  • Default Sun Java / Eclipse code style (a default config for eclipse can be found at the project root eclipse-ninja-format.xml.
  • If you change only tiny things only reformat stuff you actually changed. Otherwise reviewing is really hard.
  • We use spaces / 4 spaces as a tab in all files (java, xml…).
  • Files in git repo should have unix (LF) file endings. We are using the .gitattributes file to handle that for you.
  • All files are UTF-8.

Releasing

Making a Ninja release

1) Preparations

  • Make sure you are using http://semver.org/ for versioning.
  • Make sure changelog.md is updated
  • Make sure upgrade-guide top version is updated
  • Make sure the archetypes are up-to-date (Ninja version must match release version)
  • Make sure the archetypes version in docu (JPA + getting_started) matches release version

2) Release to central maven repo

3) Publish website

  • git checkout TAG
  • cd ninja-core
  • mvn site site:deploy

And back to develop:

  • git checkout develop
