A: SemaphoreCI provides robust error handling and retry mechanisms to handle failures in pipelines. If a job fails during the execution of a pipeline, SemaphoreCI automatically stops the pipeline and marks it as failed, allowing teams to investigate the issue. Teams can set up custom error handlers in their pipelines to retry failed jobs, skip failed jobs, or send notifications to the relevant stakeholders. SemaphoreCI also provides detailed logs and debugging tools, helping teams to identify and resolve issues quickly.
