Question

How do I get system property from teamcity in msbuild file?

teamcity version:6.0

Answer 1

Try removing system_ part from property’s name.

The documentation says

• Don’t forget to leave the “system.” part out of the system
  properties.
• When using MSBuild, replace “.” with “_” when you reference
  property names.

(However this is version 6.5 documentation, maybe it woun’t work in your case but you can try it anyway)
