Looks like your task is quite specific, and probably the GIt step is not a
The Git step is made to actually do some CI of the repository, here it does
not look like you are building a CI for opencv, but rather building a CI
for a derived package.
So I would rather use a shell script that does the necessary checkout, and
branching, and patch applying.
Obviously, you wont be able to implement the smarts that the Git step has
(inclding reuse of the previous build's workdir), but this should work
especially if you are not very confortable with python.
