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, refer http://svnbook.red-bean.com/.) The following sections describe this process:
...
A WSO2 platform release is a set of WSO2 products based on the same Carbon release. For example, Turing is the platform release name for WSO2 Carbon 4.2.0 and the WSO2 products that are based on it. Usually, not all products in a platform get released at the same time, so they are released in chunks, each of which contains the Carbon release and a subset of products. For example, chunk 11 of the Turing platform release contains Carbon 4.2.0 plus BRS 2.1.0 and other products. When you want to build a product from source, you download and build the appropriate platform chunk. (To determine which chunk to use for a specific product version, refer the Release Matrix).You
Checking out the patches
Before checking out the product source, you need to checkout the patches related to the Carbon chunk using the following command, before checking out the product source. .
$ svn checkout https://svn.wso2.org/repos/wso2/carbon/kernel/branches/4.2.0/patches/ <local-platform-directory-1>| Info |

Downloading the product source
For products based on WSO2 Carbon 4.2.0, use the below command to download the product source:
$ svn checkout https://svn.wso2.org/repos/wso2/carbon/kernelplatform/branches/4.2.0/patches/tags/turing-<release-chunk>/ <local-platform-directory-1>2>
Replace <release-chunk> with the release chunk, on which the specific product version is based on. To find out the respective release chunk, see the Release Matrix.
BRS 2.1.0 is released in Turing chunk 11, which you can download using the checkout command as shown below (replace <localDir><local-platform-directory> with a meaningful name, such as wso2carbon-platform):

Building the product

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="-Xms768m -Xmx3072m -XX:MaxPermSize=1200m"to avoid the MavenOutOfMemoryError.
To create complete release artifacts of the products released with this chunk version, including the binary and source distributions, go to <local-platform-directory> /repos/wso2/carbon/platform/tags/turing-chunk11/product-releases/chunk-11 and run the following Apache Maven commands. To build only selected products, open <localDir/repos/wso2/carbon/platform/tags/turing-chunk11/product-releases/chunk-11/products/pom.xml file, comment out the products you do not want to build, and run the relevant Maven command.
| Command | Description |
|---|---|
mvn clean install -Dproduct=brs | The binary and source distributions |
mvn clean install -Dmaven.test.skip=true | The binary and source distributions, without running any of the unit tests. |
mvn clean install -Dmaven.test.skip=true -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. |
