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

Question

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:

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 :)

Docs - BuildOptions.AcceptExternalModificationsToPlayer: http://docs.unity3d.com/ScriptReference/BuildOptions.AcceptExternalModificationsToPlayer.html

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

$$anonymous$$aking sure the folder exists for Android works. For iOS, making sure the folder exists and setting BuildOptions to BuildOptions.None still does not resolve the issue. In fact, when the iOS build runs with BuildOptions.None and the folder exists, at some point the folder gets deleted and that same error gets thrown.

Hi, I've had another look and you also shouldn't have a slash at the end of your ios path. Change path + "/ios/" to path + "/ios" I've tested this my end and it works. If it fixes your problem I'll update the answer :)

I can indeed confirm that this works. Thank you very much for your assistance, and I would highly recommend that you pass this feedback on to whomever is in charge of documentation, because all of this could've been avoided with better documentation.

Things like certain build outputs requiring folders to exist and others not requiring them, certain build outputs accepting forward slashes at the end of the path and others not accepting that, all of this should be documented.

Awesome! I've updated the answer in case other people stumble across this. I'll forward your feedback to the documentation $$anonymous$$m as well :)
