Want to hack on osgi.enroute? Here are instructions to get you started. They are probably not perfect, please let us know if anything feels wrong or incomplete.
When reporting issues on GitHub please include the steps required to reproduce the problem if possible and applicable. This information will help us review and fix your issue faster.
The only thing you need to build is Java 11. We use Maven to build and the repo
includes mvnw. You can use your system mvn but we require
at least version 3.1.0.
./mvnw package - Assembles and tests the projects
./mvnw install - Assembles and releases the projects into your local repository.
We use Travis CI and AppVeyor and the repo includes
.travis.yml and appveyor.yml files to build.
We use git triangular workflow. This means that no one, not even the osgi.enroute maintainers, push contributions directly into the main osgi.enroute repo. All contribution come in through pull requests. So each contribtor will need to fork the main osgi.enroute repo on GitHub. All contributions are made as commits to your fork. Then you submit a pull request to have them considered for merging into the main osgi.enroute repo.
After forking the main osgi.enroute repo on GitHub, you can clone the main repo to your system:
git clone https://github.com/osgi/osgi.enroute.git
This will clone the main repo to a local repo on your disk and set up the origin remote in Git.
Next you will set up the the second side of the triangle to your fork repo.
cd osgi.enroute
git remote add fork git@github.com:github-user/osgi.enroute.git
Make sure to replace the URL with the SSH URL to your fork repo on GitHub. Then we configure the local repo to push your commits to the fork repo.
git config remote.pushdefault fork
So now you will pull from origin, the main repo, and push to fork, your fork repo.
This option requires at least Git 1.8.4. It is also recommended that you configure
git config push.default simple
unless you are already using Git 2.0 where it is the default.
Finally, the third side of the triangle is pull requests from your fork repo to the main repo.
Make sure to set up Travis CI for your fork repo to test your commits when they are pushed to your fork repo. Travis CI will also build any pull requests you submit.
We are always thrilled to receive pull requests, and do our best to process them as fast as possible. Not sure if that typo is worth a pull request? Do it! We will appreciate it.
If your pull request is not accepted on the first try, don't be discouraged! If there's a problem with the implementation, hopefully you received feedback on what to improve.
Any significant improvement should be documented as a GitHub issue before anybody starts working on it.
Please take a moment to check that an issue doesn't already exist documenting your bug report or improvement proposal. If it does, it never hurts to add a quick "+1" or "I have this problem too". This will help prioritize the most common problems and requests.
Fork the repo and make changes on your fork in a feature branch:
- If it's a bugfix branch, name it XXX-something where XXX is the number of the issue
- If it's a feature branch, create an enhancement issue to announce your intentions, and name it XXX-something where XXX is the number of the issue.
Run the full build including all the tests, if any, in your branch before submitting a pull request. Having Travis CI set up for your fork repo is quite a help here.
Write clean code. Universally formatted code promotes ease of writing, reading,
and maintenance. We use Eclipse and all the projects have Eclipse .settings which
will properly format the code. Make sure to avoid unnecessary white space changes
which complicate diffs and make reviewing pull requests much more time consuming.
Pull requests descriptions should be as clear as possible and include a reference to all the issues that they address.
Pull requests must not contain commits from other users or branches.
Commit messages must start with a short summary (max. 50 chars) written in the imperative, followed by an optional, more detailed explanatory text which is separated from the summary by an empty line.
index: Remove absolute URLs from the OBR index
The url for the root was missing a trailing slash. Using File.toURI to
create an acceptable url.
Review comments may be added to your pull request. Discuss, then make the suggested modifications and push amended commits to your feature branch. Be sure to post a comment after pushing. The new commits will show up in the pull request automatically, but the reviewers will not be notified unless you comment.
Before the pull request is merged, make sure that you squash your commits into
logical units of work using git rebase -i and git push -f. After every
commit, the repo must be buildable.
Commits that fix or close an issue should include a reference like Closes #XXX
or Fixes #XXX, which will automatically close the issue when merged.
The sign-off is a simple line at the end of the commit message which certifies that you wrote it or otherwise have the right to pass it on as an open-source patch. The rules are pretty simple: if you can certify the below (from developercertificate.org):
Developer Certificate of Origin
Version 1.1
Copyright (C) 2004, 2006 The Linux Foundation and its contributors.
660 York Street, Suite 102,
San Francisco, CA 94110 USA
Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.
Developer's Certificate of Origin 1.1
By making a contribution to this project, I certify that:
(a) The contribution was created in whole or in part by me and I
have the right to submit it under the open source license
indicated in the file; or
(b) The contribution is based upon previous work that, to the best
of my knowledge, is covered under an appropriate open source
license and I have the right under that license to submit that
work with modifications, whether created in whole or in part
by me, under the same open source license (unless I am
permitted to submit under a different license), as indicated
in the file; or
(c) The contribution was provided directly to me by some other
person who certified (a), (b) or (c) and I have not modified
it.
(d) I understand and agree that this project and the contribution
are public and that a record of the contribution (including all
personal information I submit with it, including my sign-off) is
maintained indefinitely and may be redistributed consistent with
this project or the open source license(s) involved.
then you just add a line to end of the git commit message:
Signed-off-by: Joe Smith <joe.smith@email.com>
using your real name. Sorry, no pseudonyms or anonymous contributions.
Many Git UI tools have support for adding the Signed-off-by line to the end of your commit
message. This line can be automatically added by the git commit command by using the -s option.
There are some exceptions to the signing requirement. Currently these are:
- Your patch fixes spelling or grammar errors.
The osgi.enroute maintainers will review your pull request and, if approved, will merge into the main repo.
- Step 1: learn the repo inside out
- Step 2: make yourself useful by contributing information, bugfixes, support etc.
- Step 3: introduce your self to the other maintainers
Don't forget: being a maintainer is a time investment. Make sure you will have time to make yourself available. You don't have to be a maintainer to make a difference on the project!
