Quick Tips Quick tip #1: As indicated by Danny in this post, searching your full build log for 'BuildPipeline:BuildPlayerInternalNoCheck' may lead you to the actual reason for your build failure, which might not be flagged/colored as an error in the log text. If you resolve your issue this way, please post a reply with the error text that you found. These findings will be added to our existing error detection to constantly improve it going forward. Quick tip #2: Some of these failures are caused by multiple copies of a plugin DLL for different architectures, that are still set to 'Default' platform in the Unity editor. We are adding to our error indication to flag these in the build log, but in the meantime here are some links to resources that may help resolve that specific issue: (Vuforia-specific) Unity Cloud Build not working - vuforia 6 - Unity 5.4.0f3 (Plugin collisions) Why does Unity 5.4 include the contents of Plugins/Android to iOS Project? ----- Issue: Build failures with no indicated errors in log Status: Ongoing Improvement This thread has been created to capture any information on scenarios where a build has failed for you in Cloud Build, but does not clearly indicate what the problem may be.
