With the 0.4.0 preview of mediation I cannot build on Android. We are using Perforce for source control and I suspect this is the problem. When building Unity tries to checkout the MediationAdapterDependencies.xml and fails. See below and attached: UnauthorizedAccessException: Access to the path "E:\p4\Game\proto_1\Assets\Editor\MediationAdapterDependencies.xml" is denied. at System.IO.FileStream..ctor (System.String path, System.IO.FileMode mode, System.IO.FileAccess access, System.IO.FileShare share, System.Int32 bufferSize, System.Boolean anonymous, System.IO.FileOptions options) [0x0019e] in <695d1cc93cca45069c528c15c9fdd749>:0 Even though this was a local build, I've seen this issue a lot when combing Cloud Build, Perforce and other .xml files. It's part of the reason we moved away from those "other mediation" companies. For now I've reverted to 0.3.0 which does not have this build error. Is there a way, through scripting, to switch source control to Offline mode before building? I think this would solve some of the other build issues we've been having with Perforce.
