WSO2 invites you to contribute by http://svnbook.red-bean.com.) The following sections describe this process:from the Subversion (SVN) source control system, and making changes, and then back to the source repository. (For more information on Subversion, see
Building from source is optional. Users who do not want to make changes to the source code can simply download the binary distribution of the product and install it.
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 8 of the
Turing platform release contains Carbon 4.2.0 plus Task Server 1.1.0, Data Services Server 3.2.0 and Complex Event Processor 3.1.0.
Before checking out the product source, you need to checkout the patches related to the Carbon chunk using the following command.
$ svn checkout https://svn.wso2.org/repos/wso2/carbon/kernel/branches/4.2.0/
<local-platform-directory-1> with a meaningful name, such as
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/platform/tags/turing-<release-chunk>/ <local-platform-directory-2>
<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. For example, for products based on Chunk 08 of WSO2 Carbon 4.2.0, the command is as follows:
$ svn checkout https://svn.wso2.org/repos/wso2/carbon/platform/tags/turing-chunk08/ <local-platform-directory-2>
Before you edit the source code in your IDE, set up your development environment by running one of the following commands:
|If you are using this IDE...||Run this command...||Additional information|
If you are using a later Eclipse version and if you get errors (library path etc.) when trying to import the source code using the Existing Projects into Workspace, follow the steps below to solve them by importing the source code as a Maven project.
mvn clean install
Follow the instructions below to build the product after editing the source code:
MAVEN_OPTS="-Xms1024m -Xmx4096m -XX:MaxPermSize=1024m" to avoid the Maven
Navigate to each folder representing the patches within the
<local-platform-directory-1> and run the following Apache Maven commands to build the patches. For information on the patches, which are applicable for the respective Carbon chunk release, go to Release Matrix.
The binary and source distributions of the chunk release.
|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've already built the source at least once.|
<release-chunk>/and run the Apache Maven commands stated in the above step. To build only a selected product/s , open file, and comment out the products you do not want to build and run the relevant Maven command.
After building the source , you can find the artifacts/product binary distribution package of the product in the
If you are a committer, you can commit your changes using the following command (SVN will prompt you for your password):
