WSO2 products, such as Application Server are shipped as binary packs, which contains a wide variety of features to support your enterprise requirements. You can easily download the binary distribution, and get started with the product immediately.
However, as developers, if you want to enhance or modify certain features in the product, or introduce completely new functionality, you can do that by downloading the source code, making the necessary changes and building your own customized product.
The following topics describe this process:
Downloading the source
The source code of all WSO2 products are maintained in GitHub as a list of repositories. Each of the WSO2 products are built using the source code stored in several of these repositories. Given below is the list of Git repositories that are used for building the WSO2 AS 5.3.0 release.
WSO2 Carbon Kernel
Follow the steps given below to download each of the above repositories for AS 5.3.0.
Clone the relevant Git repository to a folder of your choice. The location of the extracted source is referred to as <gitrepo
_SOURCE_HOME>. For example, to clone the Git repository for Carbon4 Kernel, use the following command:
git clonehttps://github.com/wso2/carbon4-kernel.git <carbon4kernel
Navigate to the <gitrepo
_SOURCE_HOME>directory using the following command:
Check out the tag (branch), which corresponds to the AS 5.3.0 release, to a folder of your choice:
git checkout -b <REMOTE_BRANCH/TAG> <LOCAL_BRANCH>
For example, to check out the tag for Carbon4 Kernel, use the following command:
git checkout -b v4.4.1 v4.4.1
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 AS 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.
Building the product
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 section.
