Standalone MacOS build - PlayerIcon.icns problem

Hello,

I'm using Unity with command line. To generate Standalone MacOSX build, I used this command :

 -quit -batchmode -nographics -projectPath "C:\Program Files (x86)\Jenkins\userContent\AngryBots" -buildOSXPlayer "$WORKSPACE/Builds/AngryBirds"

I noticed that the AngryBirds.app application is well generated, but I have this problem in the build steps :

 Cancelling DisplayDialogComplex: Opening file failed Opening file C:\Program Files (x86)\Jenkins\jobs\MacOSAppWindows\workspace/Builds/AngryBirdsX/Contents/Resources/**PlayerIcon.icns** failed: The specified path is not found.

This error is not generated when I build with Unity Editor and the PlayerIcon.icns is well generated in the specific folder.

I can't understand the problem, should I use postBuildProcessor to create PlayerIcon.icns ?
