Can't get basic Powershell script running inside Team City

The stdin command option of Powershell has some weirdness around multiline commands like that.

You script in the following form would work:

write-host "test"write-host "test2"if("1" -eq "1"){write-host "test3 in if"} else {write-host "test4 in else"}

The ideal way would be to use the Script : File option in TeamCity which will will run the script you specify using the -File parameter to Powershell.

If you don't want to have a file and having VCS, in the current setup, change Script Execution Mode to Execute .ps1 file with -File argument.

I've had this problem with inline powershell scripts with TeamCity (right up until the current version of 7.1.3). I've found the problem to be the tab character rather than multi-line statements. Try replacing the tab characters with spaces (while still remaining multi-line) and the script should run fine.

You could try putting the brace opening the block on the same line as the If.

I.e.,

If ('1' -eq '1') {    ...}Else {    ...}

That's the usual styling you see with Powershell, and obviously, putting the braces on the next line can cause problems.
