WSO2 invites you to contribute by downloading from the GitHub source control system, and making changes, and then back to the source repository. The following sections describe this process:
|Table of Contents|
WSO2 products are built on top of WSO2 Carbon Kernel, which contains the Kernel libraries used by all products. When there are changes in the Carbon Kernel, they are bundled and released in a new WSO2 Carbon version (for example, WSO2 Carbon 4.4.1). You can download the complete WSO2 Kernel release using the following repository: https://github.com/wso2/carbon4-kernel, which is recommended if you intend to modify the source.
After the source code is downloaded, you can start editing. However, it is recommended to run a build prior to changing the source code to ensure that the download is complete.
Editing the source code
Now that you have downloaded the source code for the Carbon project from GitHub, you can prepare your development environment and do the required changes to the code.
To edit the source code in your IDE, set up your development environment by running one of the following commands:
IDE Command Additional information Eclipse
http://maven.apache.org/plugins/maven-eclipse-plugin IntelliJ IDEA
- Add the required changes to the source code.
Ensure that the following prerequisites are in place before you build:
- Make sure the build server has an active Internet connection to download dependencies while building.
- Install Maven and JDK. See Installation Prerequisites for compatible versions.
- Set the environment variable
MAVEN_OPTS=”-Xms1024m -Xmx4096m -XX:MaxPermSize=1024m” to avoid the Maven
Use the following maven commands to build your product:
The binary and source distributions.
|The binary and source distributions, without running any of the unit tests.|
|The binary and source distributions, without running any of the unit tests, in offline mode. This can be done only if you have already built the source at least once.|
Committing your changes
You can contribute to WSO2 products by committing your changes to GitHub. Whether you are a committer or a non-committer, you can contribute with your code as explained in the Get Involved sectionWSO2 Application Server as well as all other WSO2 products are maintained in GitHub repositories. If you are a developer, you can clone the source code from these Git repositories, and if required, you can do modifications and build a customized product on your own. WSO2 invites interested parties to contribute their changes and suggestions to WSO2.
See the documentation on working with the source code for more information.
