My organization has been using a self-hosted Jenkins setup for years, but the maintenance of plugins and "dependency hell" is becoming a full-time job. With the rise of GitHub Actions and its deep integration with the repository, is it worth the migration effort for a complex Java-based enterprise application?

We made the switch last year for our Spring Boot microservices and haven't looked back. The biggest advantage isn't just the syntax; it's the managed infrastructure. No more patching Jenkins servers or worrying about disk space on build agents. However, be prepared for the pricing model shift. Jenkins is "free" but high maintenance; GitHub Actions is pay-as-you-go. For our complex workflows, we had to use "Reusable Workflows" and "Composite Actions" to keep things DRY. If you have very specific, legacy on-prem requirements, Jenkins might still be a necessary evil.
Did you face any significant hurdles with security secrets or connecting to your private VPC when moving to a cloud-managed CI tool?
Jenkins still has a better plugin ecosystem for niche edge cases. If you have a highly customized build process, you might find GitHub Actions a bit limiting.
Laura is right about the plugins, but the "Actions Marketplace" is catching up fast. We found that most things we did with Jenkins plugins could be replaced by a simple shell script or a pre-built Action.
