Running background jobs on Grails? Two gotchas:
🪤 GORM owns the DataSource, JobRunr's auto-config cannot find it
🪤 Groovy closures ≠Java SAM lambdas
New guide: both fixed, plus a full demo.

JobRunr Grails just got a solid official guide working sample app:
jobrunr.io/en/guides/jvm-fra…
github.com/iNicholasBE/grail…
Quartz has been the default for years (it stalled ~2021 then revived recently), so many teams still stick with it.
JobRunr is an excellent modern option.

Grails has approximately 6,400 GitHub stars in total across all Grails-related repositories under these github orgs (grails/, grails-plugins/, gpc/, and apache/grails- repos). But they are very spread out.
Please help the project by staring the main repo: github.com/apache/grails-cor…

All the Grails Guides have been migrated over to the official Apache Grails site → grails.apache.org/guides/
Even better news: the process for adding new guides has been completely overhauled and is now ridiculously simple and fast.

Just wrapped my talk at @arcofai in Austin yesterday.
75 minutes on AI coding agents for full-stack Java dev in @jetbrains @intellijidea.
Here's what we covered...
AI coding agents aren't autocomplete anymore. They write entire features, generate tests, and produce docs. The shift is real and it's fast.
We did a live head-to-head: @GitHubCopilot vs @jetbrains Junie, running Claude, GPT, Gemini, and Grok side-by-side inside IntelliJ IDEA 2026.1. And then topped it off with an @opencode demo.
The stack I used: @springboot @grailsframework. Why Grails? Groovy gives you ~30-40% better token efficiency vs pure Java. That matters a lot when you're hitting context limits.
We also got real about the pitfalls:
↳ Hallucinations inventing fake methods and plugins
↳ Context loss mid-session on large codebases
↳ Security risks from unreviewed AI commits
↳ Over-reliance leading to hidden tech debt
And I showed my GitHub contribution graph: 7,744 contributions in the last year. Agentic engineering acceleration is not theoretical.
The audience brought great energy and sharp questions. Austin did not disappoint. 🚀

🚀 Grails Migration Win: 6 Months to 9 Days
Huge shoutout to Forrest Evans, Product Manager at @Rundeck at @pagerduty!
He crushed a full Grails 6 to 7 migration in just 9 days. The project was originally scoped for 6 months with big costs!
Have you upgraded to Grails 7 yet?
