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:

Building from source is optional. Users who do not want to make changes to the source code can simply download the binary distribution of WSO2 Business Rules Server and install it.

Checking out the source 

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 4.2.0).

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).

BRS 2.1.0 is released in Turing chunk 11, which you can download using the checkout command as shown below (replace <localDir> with a meaningful name, such as wso2carbon-platform):

$ svn checkout https://svn.wso2.org/repos/wso2/carbon/platform/tags/turing-chunk11 <local-platform-directory>

Building the product 

Following are the Apache Maven commands you can run to create complete release artifacts of WSO2 Business Rules Server, including the binary and source distributions. If you only want to build Business Rules Server, use the -Dproduct=brs option as shown. If you want to build the entire Carbon core project, omit the -Dproduct=brs option.

Before you build:

  1. Make sure the build server has an active Internet connection to download dependencies while building.
  2. Install Maven and JDK. See Installation Prerequisites for compatible versions.
  3. Set the environment variable  MAVEN_OPTS=”-Xms768m -Xmx3072m -XX:MaxPermSize=1200m to avoid the Maven OutOfMemoryError.
CommandDescription
mvn clean install -Dproduct=brsThe binary and source distributions
mvn clean install -Dmaven.test.skip=trueThe binary and source distributions, without running any of the unit tests.
mvn clean install -Dmaven.test.skip=true -oThe 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.

Setting up your development environment

Before you edit the source code in your IDE, set up your development environment by running one of the following commands:

IDECommandAdditional information

Committing your changes 

If you are a committer, you can commit your changes using the following command (SVN will prompt you for your password):

$ svn commit --username your-username -m "A message"
