[devel at bb.net] Accessing step result in the factory

[Pierre Tardy]

Hi Aakash,

The BuildFactories cannot be dynamic like you say, because they are run at
the begining of the build.

You can use doStepIf in order to do that, or you can also use a customStep,
with dynamicSteps.
You have an example in the doc:
http://docs.buildbot.net/latest/manual/cfg-buildfactories.html#dynamic-build-factories

Regards
Pierre
