Patching WSO2 BPS - Carbon

I am attempting to patch the carbon app within our WSO2 BPS 3.2.0 environment. We are currently runnning 4.2.0 patch0005 which was bundled with BPS. There is a fix in patch0007 that resolves a bug we are experiencing. Does anyone have a working processes including the steps to download the patch source?

I see there is a service pack listed here... https://svn.wso2.org/repos/wso2/carbon/kernel/branches/4.2.0/service-packs/, but this does not include the jar files needed for the service pack.

I'd appreciate a point in the right direction.

Thanks!

Solution

Here's how you can build and apply the patch0007:

Pre-requisites:

Java 1.6 (it won't build with 1.7 or later versions)
Maven 3.0.5 (may have problems with later versions so try to install this version)

How to build:

Checkout Kernel 4.2.0 (https://svn.wso2.org/repos/wso2/carbon/kernel/branches/4.2.0/)
Build the kernel (mvn clean install -Dmaven.test.skip=true) - this step is optional and you may proceed to the next step without this, but if you face any problems, then start from this step. This will take some time.
Goto patches directory
Build each patch from 0001 to 0007 in that order (it's important to perform this in order without missing any)
Now you have built all patches upto 7, now you have to apply both patch0006 and patch0007 to the BPS (it already has upto patch0005)
Those patches are in patch0006/distribution/target/WSO2-CARBON-PATCH-4.2.0-0006.zip and a similar location for patch0007
unzip those files and take patch0006 and patch0007 directories from them and copy to <BPS>/repository/components/patches
restart the server
