 Contributing to Apache Commons JEXL
 ======================

 You have found a bug or you have an idea for a cool new feature? Contributing code is a great way to give something back to
 the open source community. Before you dig right into the code there are a few guidelines that we need contributors to
 follow so that we can have a chance of keeping on top of things.

 Getting Started
 ---------------

 + Make sure you have a [JIRA account](https://issues.apache.org/jira/).
 + Make sure you have a [GitHub account](https://github.com/signup/free).
 + If you're planning to implement a new feature it makes sense to discuss your changes on the [dev list](https://commons.apache.org/mail-lists.html) first. This way you can make sure you're not wasting your time on something that isn't considered to be in Apache Commons JEXL's scope.
 + Submit a [Jira Ticket][jira] for your issue, assuming one does not already exist.
   + Clearly describe the issue including steps to reproduce when it is a bug.
   + Make sure you fill in the earliest version that you know has the issue.
 + Find the corresponding [repository on GitHub](https://github.com/apache/?query=commons-),
 [fork](https://help.github.com/articles/fork-a-repo/) and check out your forked repository.

 Making Changes
 --------------

 + Create a _topic branch_ for your isolated work.
   * Usually you should base your branch on the `master` branch.
   * A good topic branch name can be the JIRA bug id plus a keyword, e.g. `JEXL-123-InputStream`.
   * If you have submitted multiple JIRA issues, try to maintain separate branches and pull requests.
 + Make commits of logical units.
   * Make sure your commit messages are meaningful and in the proper format. Your commit message should contain the key of the JIRA issue.
   * e.g. `JEXL-123: Close input stream earlier`
 + Respect the original code style:
   + Only use spaces for indentation.
   + Create minimal diffs - disable _On Save_ actions like _Reformat Source Code_ or _Organize Imports_. If you feel the source code should be reformatted create a separate PR for this change first.
   + Check for unnecessary whitespace with `git diff` -- check before committing.
 + Make sure you have added the necessary tests for your changes, typically in `src/test/java`.
 + Run all the tests with `mvn clean verify` to assure nothing else was accidentally broken.

 Making Trivial Changes
 ----------------------

 The JIRA tickets are used to generate the changelog for the next release.

 For changes of a trivial nature to comments and documentation, it is not always necessary to create a new ticket in JIRA.
 In this case, it is appropriate to start the first line of a commit with '(doc)' instead of a ticket number.


 Submitting Changes
 ------------------

 + Sign and submit the Apache [Contributor License Agreement][cla] if you haven't already.
   * Note that small patches & typical bug fixes do not require a CLA as
     clause 5 of the [Apache License](https://www.apache.org/licenses/LICENSE-2.0.html#contributions)
     covers them.
 + Push your changes to a topic branch in your fork of the repository.
 + Submit a _Pull Request_ to the corresponding repository in the `apache` organization.
   * Verify _Files Changed_ shows only your intended changes and does not
   include additional files like `target/*.class`
 + Update your JIRA ticket and include a link to the pull request in the ticket.

 If you prefer to not use GitHub, then you can instead use
 `git format-patch` (or `svn diff`) and attach the patch file to the JIRA issue.
