I really like the new “auto detect Unity version” feature in UCB. However, in order for this feature to be really useful we need for UCB to support new Unity version at the same time as they’re available through Unity Hub. Right now I get the following error:
1: Detected project using Unity Version 2019_2_8f1, but this version is not available currently. Please update your project to use a supported version of Unity, or manually select a version for Cloud Build to build with.
There’s always a brief delay for us to make sure that the version works correctly in UCB, usually nothing goes wrong with these small upgrades but we still need to validate that everything is being stored by the datacenter correctly and everything was configured correctly when the version entry was created. We do have some major improvements in the works to try and help this situation along though.
There’s probably no way to avoid this particular situation where there’s a day’s lag between the version being released to the public and being released to UCB (unless we can somehow convince release management to delay every Unity release, but that’s the tail wagging the dog I think). However, something which we do have planned soon is to make robust fallbacks for the Unity version detection so that you will rarely ever see that message. Instead, in this case you probably would have built the project using 2019_2_7f1 while we wait for the new version to roll out.
