Build failure because of... App Icons ?!

Hi :slight_smile:
I’ve an error when I build my app. I’m on Mac, and with the ionic build ios command, I’ve these errors in my terminal :

CpResource MHB\ App/Resources/splash/Default-736h.png build/emulator/MHB\ App.app/Default-736h.png
CpResource MHB\ App/Resources/icons/icon-40@2x.png build/emulator/MHB\ App.app/icon-40@2x.png
CpResource MHB\ App/Resources/icons/icon-76.png build/emulator/MHB\ App.app/icon-76.png
CpResource MHB\ App/Resources/icons/icon.png build/emulator/MHB\ App.app/icon.png
CpResource MHB\ App/Resources/icons/icon@2x.png build/emulator/MHB\ App.app/icon@2x.png
CpResource MHB\ App/Resources/icons/icon-72.png build/emulator/MHB\ App.app/icon-72.png
CpResource MHB\ App/Resources/icons/icon-50.png build/emulator/MHB\ App.app/icon-50.png
CpResource MHB\ App/Resources/icons/icon-60@2x.png build/emulator/MHB\ App.app/icon-60@2x.png

I’ve generated the splash screen and app icons, using ionic resources, and it works well. The path to the images in the error lines are totally valid : no image is missing.

So, how can I solve this problem ? And does someone know the cause of that issue ?

Thanks for answers ^^
