The Auto-build option for a build target is automatically disabled if the target hasn't been built for 30 days. Symptoms include inability to enable Auto-build or it resetting immediately. To resolve, manually build the target once via Build Automation Build History, then Auto-build can be re-enabled. More details are available in the Unity Build Target Configuration documentation.
Symptoms:
- When I enable Auto-build in my build target configuration, it resets immediately after.
- I am not able to enable Auto-builds in my build target configuration.
- I had a build target configuration set to Auto-build but it has become disabled and I cannot re-enable it.
Cause:
- When a build target hasn't been built for 30 days, the Auto-build option is disabled automatically.
Resolution:
- To re-enable the Auto-build setting in the Configuration, the build target needs to be built manually once. Run a manual build of the build target (next step), then you should be able to re-enable Auto-build for that build target.
- To run a manual build, navigate to Build Automation > Build History, select Build, and then choose your target and build in the UI that comes up.
