有没有办法在Shell脚本中修改TeamCity系统属性？

Question

I'm trying to figure out how to modify some custom system properties that I've defined in the build configurations parameters.

For example, if I have a system property named system.TestProperty with value 0 and I want to modify it's value from shell, I've tryed using ##teamcity[setParameter name='system.TestProperty' value='1'] as explained here but the next time I get it's value, it gives me 0 again. The script i'm using to test:

Write-Host "-------------"
$testProperty = "%system.TestProperty%"
Write-Host "system.TestProperty: $testProperty"

Write-Host "##teamcity[setParameter name='system.TestProperty' value='1']"

$testProperty = "%system.TestProperty%"
Write-Host "system.TestProperty: $testProperty"
Write-Host "-------------"

What I'm getting:

-------------
system.TestProperty: 0
##teamcity[setParameter name='system.TestProperty' value='1']
system.TestProperty: 0
-------------

You wont see the parameter updated in the same script. If you split the check into another build step, you should see it there.
