Below are three PowerShell Commands run in Jenkins and the build result. Why it fails? Which command could be failing? I've read this post: How/When does Execute Shell mark a build as failure in Jenkins?, but couldn't figure out. I am not familiar with MS stuffs.
Command 1:
& "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.com" "$env:WORKSPACE\ETL\OnePnL.sln" /Build
Command2:
###########################
# Deploy SSIS package           #
###########################  
$csource ="$env:WORKSPACE\ETL\Project Type 0\bin\DEFAULT\OnePnL.ispac"
$cserver = "SSASDBDEV01"
$cdest = "/SSISDB/OnePnL/OnePnL"    
echo $env:GIT_BRANCH    
if ($env:GIT_BRANCH  -like '*master*')
{
   # Call IS Deployment Wizard
   echo "Deploying SSIS package to $cdest on $cserver"    
   # "C:\Program Files (x86)\Microsoft SQL Server\110\DTS\Binn\ISDeploymentWizard.exe" "/Silent /SourcePath:""$csource""    #/DestinationPath:""$cdest"" /DestinationServer:""$cserver""" -Wait
   Start-Process "C:\Program Files (x86)\Microsoft SQL Server\110\DTS\Binn\ISDeploymentWizard.exe" "/Silent /SourcePath:""$csource""    /DestinationPath:""$cdest"" /DestinationServer:""$cserver""" -Wait
}
Command 3:
#####################
# Copy Files to O: drive #
#####################
#Make build directory
#$outputparentdir = "\\orion\Shared\AppUpload\ApplicationPackage\OnePnL Cube\SSIS Jenkins Builds"
$outputparentdir = "\\inv\Shared\Transfer - Deleted Weekly\Jenkins\BI\OnePnL\SSIS Jenkins builds"
$outputdir = "$outputparentdir\${env:GIT_BRANCH}\Build ${env:BUILD_NUMBER}"
echo "Branch"
echo ${env:GIT_BRANCH}
echo "Output directory"
echo $outputdir 
if (!(Test-Path "$outputparentdir"))
{
  mkdir $outputparentdir
}
mkdir $outputdir
ROBOCOPY "$env:WORKSPACE\ETL\Project Type 0\bin\DEFAULT" "$outputdir" /E /v
echo "Done Copy"
Build result:
