Flexible publish doesn't define the behavior when some of publishers fail.
Current implementation works like this:
|Component||Behavior when some of publishers fail|
|Jenkins core||Run all publishers|
|Flexible publish (by condition)||Run all publishers|
|Flexible publish (in a condition)||Stop running following publishers|
Flexible-publish is featured just to run publishers conditionally and should work as Jenkins core in other aspects.
In flexible-publish 0.15, I'll explicitly define the behavior when publishers fail.
I introduce execution strategy and users can now define how flexible publish behaves when some publisher fail.
