Bamboo 5.1.1 pre-build action issue

[Shaahul Hameed]

We are having two Build projects which has some build plans and we are always running a clean checkout for all plans.

We are using Build Number stamper plugin to generate "build-number.txt". This plugin runs as a pre-build action.

In Project 1 pre-build action runs after "Checkout Default Repository" task and hence our generated build-number.txt is retained

In Project 2 pre-build action runs at the start i.e. before "Checkout Default Repository" and since we always do a clean build. The task 'Checkout Default Repository" removes build-number.txt.

I have looked in every tab and in miscellaneous tab in the corresponding Job and I cannot find were this behavious is defined.

Appreciate if someone please shed some light on this

The pre-build action are deferred after Checkout Task if this is the first task in the Job.(more precisely it is executed before the first task which is not 'initialising task', so if you have 2 checkout tasks at the beginning the pre-build action would be executed after both of them. But if you put script task at the top it is executed before it)

In your case the solution would be to move disabled task down the pipeline (since you don't use it anyway).

Thanks for the answer Marcin.

Is it the default behaviour or is there way to run pre-build action before/after any tasks?

That sequence is hard coded.
