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:
...
| Info |
|---|
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 Carbon and install it. |

Checking out the source
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 source 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 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

If you will not be committing changes, you can use HTTP instead of HTTPS to download the source anonymously, which can be faster. If you are behind a corporate firewall, however, you might need to use HTTPS if your access is blocked. |
Access through a proxy
The Subversion client can be configured to access the repository through a proxy. Specify the proxy to use in the "servers" configuration file in:
...
| Code Block |
|---|
[global] http-proxy-host = your.proxy.name http-proxy-port = 3128 |

Building the product
Following are the Apache Maven commands you can run to create complete release artifacts of WSO2 Carbon, including the binary and source distributions.
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.
| Command | Description |
|---|---|
mvn clean install | 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 have 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:
| IDE | Command | Additional information |
|---|---|---|
| Eclipse | mvn eclipse:eclipse | http://maven.apache.org/plugins/maven-eclipse-plugin/ |
| IntelliJ IDEA | mvn idea:idea | http://maven.apache.org/plugins/maven-idea-plugin/ |
