Is there a way to create a build step that is triggered before every stage of my build pipeline?

If you start some common build script then this script can always execute some code. If you're looking for pure TeamCity solution, then templates are the way to go.

Hi Pavel,

I was basically looking for a way to define a build configuration that is not tied to any projects and then define a triggering condition for it such as "Run this step whenever build configurations a, b, c, or d are run".

For example, let's pretend we have a project named "Sample Project" that has several sub projects each with a few build configurations:

+ Sample Project
+ Sub Project 1
  + Build
  + Unit Test
  + Deploy
  + Integration Test
+ Sub Project 2
  + Build
  + Unit Test
  + Deploy
  + Integration Test

I want to define a build Configuration not tied to any single Sub Project (e.g. defined on Sample Project) and configure it to get executed before the following build configurations:

* Sample Project/Sub Project 1/Build
* Sample Project/Sub Project 2/Build
* Sample Project/Sub Project 3/Build

Do you see any reasons why this might not be a good idea/feature? If not, I can submit a feature request. But if you think for one or more reasons this is not a good feature, could you please explain?

Thanks,
Behrang

Behrang, generally speaking. templates are offering all necessary functionality. Also, the in TC concepts all build actions take part in one build. There's no injection, etc.
