Unable to build to Android and iOS using BuildPipeline Failed to copy files

I get errors related to copying files when attempting to use BuildPipeline with iOS or Android (it works fine with OS X and Windows).

Here is the iOS error I get:

IOException: Failed to Copy File / Directory from 'Temp/StagingArea/Trampoline/Unity-iPhone.xcodeproj/project.pbxproj' to '/Users/wuchiang/Desktop/mygame-build/ios/Unity-iPhone.xcodeproj/project.pbxproj'.

and here is the Android error I get:

		}

		return keystoreData;
	}

For Android it looks like the path doesn’t exist.

For iOS the BuildOptions.AcceptExternalModificationsToPlayer is for appending and will only work if there is already a project to append to at the path location. It looks like this might be the reason you’re receiving the iOS error. You can remove this build option or use BuildOptions.None for when you don’t have a project to append to and need one created. Also (just like for Android) make sure the path exists prior to building.

I hope this helps :slight_smile:

Docs - BuildOptions.AcceptExternalModificationsToPlayer:

EDIT: Also, don’t put a slash at the end of the path for the iOS build. Change path + “/ios/” to path + “/ios”
