If you would like to contribute code to Auto you can do so through GitHub by forking the repository and sending a pull request.
When submitting code, please make every effort to follow existing conventions and style in order to keep the code as readable as possible.
Where appropriate, please provide unit tests or integration tests. Unit tests should be JUnit based tests and can use either standard JUnit assertions or Truth assertions and be added to <project>/src/test/java. Changes to code generation or other build-time behaviour should go into small maven projects using the maven-invoker-plugin. Examples of this are in generator/src/it and can include bean-shell verification scripts and other facilities provided by maven-invoker-plugin.
Please make sure your code compiles by running mvn clean verify which will execute both unit and integration test phases. Additionally, consider using http://travis-ci.org to validate your branches before you even put them into pull requests. All pull requests will be validated by Travis-ci in any case and must pass before being merged.
If you are adding or modifying files you may add your own copyright line, but please ensure that the form is consistent with the existing files, and please note that a Google, Inc. copyright line must appear in every copyright notice. All files are released with the Apache 2.0 license and any new files may only be accepted under the terms of that license.
Before your code can be accepted into the project you must sign the Individual Contributor License Agreement (CLA).
