Build Condition "if script evaluate true" #2929

Hi,

I'm having problem with using build condition: "if script evaluate true". What I try to do is launch build as soon as one of the folder contain specific file. I tried to use execution of powershell script but it is constantly failing to evaluate it.

Script: 

util.execute("C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe \"D:\checkifDeploymentExists.ps1" \"D:\_Deployment\"") == 1


Error message:

Failed to evaluate below expression:
mvel:util.execute("C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe \"D:\checkifDeploymentExists.ps1" \"D:\_Deployment\"") == 1


Same problem happens if I try to read file name as string and compare it to NULL value.

I am not familar with powershell, but at least single back slash has to be replaced by double back slash in QB script:
util.execute("C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe D:\checkifDeploymentExists.ps1 D:\_Deployment") == 1


If this does not work, please show me the full error message including the stack trace.

Let say I've switched to groovy.

I use following code


${groovy:
def dir  =  new File("D:\_Deployment\")
if((dir.list() as List).empty)
   return false
else
   return true
}


And I keep receiving following error:

The code itself seems to be ok, becouse it works without problem in groovy console. Any idea what may be wrong ?

Firstable, remove surrounding ${} as it is not necessary for script fields. 

groovy:
def dir  =  new File("D:\_Deployment\")
if((dir.list() as List).empty)
   return false
else
   return true


Secondly, the NPE seems to me that the dir.list() returns a null value which indicates that the directory "D:\_Deployment\" does not exist.

Yeah, my bad. I've badly assumed that build condition is evaluated on server, in fact it is evaluated on node (where the path was not existing). Thanks for help (and sorry for dumb questions).
