Powershell in MsBuild: Check if script succeeded?

Question

I am using a powershell script to perform a few tasks that are pre requisites for my MsBuild. The script is called from the build itself. How do i check if the script succeeded so that my build can continue, else fail.

Answer 1

The easiest way would be to return a non exit zero code from your script that would indicate that the build failed. So something like this at the end of the script:

if ($error) { exit 1 }

that would exit with a code of 1 if any errors occured during the script
