WSO2 invites you to contribute by checking out the source from the Subversion (SVN) source control system, building the product and making changes, and then committing your changes back to the source repository. (For more information on Subversion, see http://svnbook.red-bean.com/.) The following sections describe this process:
...
You can download the complete WSO2 Carbon platform, which is recommended if you intend to modify the source. The Carbon project comes in three sub projects: Orbit, Kernel, and Platform. Download and build them in that specific order. You can check out the complete source anonymously from Subversion (SVN) with the following commands (replace code anonymously using the checkout command as shown in the following examples. Replace x.x.x with the version of Carbon you want to build ). The Carbon project comes in three sub projects: Orbit, Kernel, and Platform. Download and build them in that particular order.and <local-x-directory>with meaningful names, such as: svn checkout https://svn.wso2.org/repos/wso2/carbon/orbit/tags/4.1.0 wso2carbon-orbit
Orbit:
$ svn checkout https://svn.wso2.org/repos/wso2/carbon/orbit/tags/x.x.x Orbit<local-orbit-directory>Kernel:
$ svn checkout https://svn.wso2.org/repos/wso2/carbon/kernel/tags/x.x.x Kernel<local-kernel-directory>Platform:
$ svn checkout https://svn.wso2.org/repos/wso2/carbon/platform/tags/x.x.x Platform <local-platform-directory>Access through a firewall
If you are behind a corporate firewall that is blocking HTTP access to the Subversion repository, you can try the developer connection to the trunk. For example:
$ svn checkout https://svn.wso2.org/repos/wso2/trunk/carbon carbonwso2carbon
Access through a proxy
The Subversion client can be configured to access through a proxy. Specify the proxy to use in the "servers" configuration file in:

Building the product

Following are the Apache Maven commands you can run to create complete release artifacts of WSO2 ESB, including the binary and source distributions. If you only want to build the ESB, use the -Dproduct=esb option as shown. If you want to build the entire Carbon core project, omit the -Dproduct=esb option.
...
- Install Maven and JDK. See Installation Prerequisites for compatible versions.
- Set the environment variable
MAVEN_OPTS=”-Xms768m -Xmx3072m -XX:MaxPermSize=1200m” to avoid the MavenOutOfMemoryError. - Make sure the build server has an active Internet connection to download dependencies while building.

|---|---|
mvn clean install -Dproduct=esb | The binary and source distributions |
mvn clean install -Dmaven.test.skip=true -Dproduct=esb | The binary and source distributions, without running any of the unit tests. |
mvn clean install -Dmaven.test.skip=true -Dproduct=esb -o | The binary and source distributions, without running any of the unit tests, in offline mode. This can be done only if you've already built the source at least once. |
