Jenkins ver. 2.7.1 Zip File permissions lost on Windows

[Nicolas Barlatier]

Hello all I need your help for an annoying side effect of Jenkins, 

when I do 

C:\Program Files (x86)\MSBuild\14.0\Bin\MSBuild.exe ${WORKSPACE}\XTR\tools\PNRViewer\PNRViewSln\Misterfly.PNRView\Misterfly.PNRView.csproj /p:VisualStudioVersion=12.0 /property:NugetDir="C:\Builds" /p:Configuration=DEBUG /p:DeployIisAppPath="PNRView"

 /T:Package /P:Configuration=Debug /P:PackageLocation="C:\Build\Nico.zip"

I got the zip file expected but it doesn't have any permission, not even read....

When I launched in CMD MS-DOS directely

C:\Users\nbarlatier>"c:\Program Files (x86)\MSBuild\14.0\bin\MSBuild.exe" "c:\Bu

ilds\PnrViewer\workspace\XTR\tools\PNRViewer\PNRViewSln\Misterfly.PNRView\Mister

fly.PNRView.csproj" /p:VisualStudioVersion=12.0 /property:NugetDir="C:\Builds" /

p:Configuration=DEBUG /p:DeployIisAppPath="PNRView" /T:Package /P:Configuration=

Debug  /P:PackageLocation="C:\zip\Nico.zip

the zip file is ok, so it must be Jenkins which removes the permissions....

could you help us figure out why Jenkins removes the file permissions and how to prevent this problem??

Thank you for your help :)

Nicolas
