Builds cancel immediately upon start

Resolve issues with Unity Build Automation builds canceling immediately upon
Read time 1 minute
Last updated 7 days ago

Symptoms

  • The Unity Build Automation (UBA) service launches a build but cancels it immediately.
  • You're unable to manually start new builds with UBA.
  • UBA doesn't produce logs when it launches a new build.

Environment

Builds from either:
  • The Build Automation configuration page
  • Build History

Causes

The most common causes of this issue are as follows:
  • Your organization is on a Free DevOps plan and your build exceeds the free usage limits.
  • You have a build minute cap in place and when the build begins, it exceeds the cap.
  • The build configuration is invalid. For example, the source control connection isn't available or, for a macOS build, the XCode version isn't available.

Resolution

Change to a consumption-based plan

If your organization is on a Free Plan and you exceed the free limits, you can upgrade to a consumption-based plan.

Change your build minute cap

If you have an active subscription, check if you use a build minute cap and whether your build exceeds the cap.
To check your cap, go to Organization > Administration > Billing & Cost > Budget alerts. If Build minutes monthly cap is enabled and you're near the limit, either disable the cap or increase the limit.

Contact the support team

Contact the Service Support team if:
  • Your plan and build minute cap aren't exceeded.
  • The Build Automation sidebar displays no issues under the DevOps menu.
To submit a ticket, from the Dashboard, go to DevOps > Help & Support > Ticket > File a ticket.
