Every Gradle 7 release has a known high-severity advisory, and your build has no patch. Now what? A rushed major upgrade costs time. The Security Subscription patches 7.6.6, so teams patch where they are and upgrade later. https://gradl.es/4BjzUOl #StateOfTheBuild #Gradle
Your root build script configures every subproject, and Isolated Projects fails the build. What replaces it? Convention plugins: each project applies shared logic to itself. https://gradl.es/3U75yOq #ReadingTheBuild #Gradle
Gradle 9.8.2 is out 🐘 🔒 Fixes 3 high-rated security vulnerabilities (upgrade recommended) ☕ Java 27 support 🪞 Reuse Maven mirror settings ⚡ Up to 45% faster builds on some Windows machines

"So we call it dependency hell." Sean Sullivan of Grubhub at a recent summit. His defenses: `failOnVersionConflict()`, dependency locking, and a bill of materials to keep libraries aligned. Which one does your build use? #FromTheStage #Gradle
Your IDE sync crawls, but turning on Isolated Projects feels too risky for your CI. Can you split it? Set the flag in gradle.properties and turn it off on the CI command line, just like the Gradle team does. https://gradl.es/4B9QjVs #OneFlag #Gradle
You're on Gradle 9.4.0, and the security fix ships only in the latest minor. Now what? Open-source fixes only reach the latest minor. The Gradle Security Subscription covers 9.2.x to 9.8.x: critical fixes within 7 days, high within 30 days. https://gradl.es/4BjhCww #AskTheDocs #Gradle
Agents can now upgrade your Gradle wrapper correctly using our new skill. We tested 7 models. How did they score? 0 of 7 models pinned it alone. With our skill, 4 scored 29/29. See the ranking: https://gradl.es/4zPEvq5 #HeadToHead #Gradle
Gradle Technologies is now Develocity, and gradle.com redirects to develocity.ai. FYI for anyone who missed the news. #Gradle #Develocity #Rebrand

Unpopular opinion: most caching problems aren't caching problems. They're "nobody looked at the Build Scan" problems.
Cold starts on ephemeral CI runners are an underrated tax. Automated cache management landed in 2026.1; 2026.2 widened Artifact Cache and Setup Cache coverage. develocity.ai/releases/

Ran a benchmark on this: same model, only difference was access to real build data. 4/40 vs 36/40 on cache miss diagnosis. Numbers are wild. develocity.ai/blog/build-caching-optimizer-benchmark/
What Build Data Adds to an AI Agent: A Benchmark | Develocity
Your AI agent can already read your build logs. We measured what changes when it can read your build data too: 36 of 40 runs solved, against 4.

Cache hit rate is the number everyone quotes. Avoidable miss rate is the one worth acting on. One is a scoreboard. The other is a to-do list.
Cache key debugging, the manual way: gradle build --scan Run it twice, from two different locations. Open both scans, diff the task inputs. That's usually where the volatile timestamp or absolute path is hiding.
Build Caching Optimizer went GA for Gradle and Maven in 2026.2. Other toolchains aren't covered by the automated fix; you still get the Build Scan data, you just go find it yourself.
We pointed a new agent-benchmarking harness at a real Gradle bug: Fable 5.1 vs Astra 6, same prompt, same 50-turn limit. Both fixed it (but not the same way). Diffs, cost, tokens, and which fix we're merging, on the blog: https://blog.gradle.org/two-agents-one-gradle-bug
Testing Astra 6 v Fable 5.1 on a Gradle docs bug
We gave two coding agents the same one-line Gradle documentation bug, the same repo, the same 50 turns, and a stopwatch. Both completed the task and fixed the bug. Here is everything that happened in ...

A build cache miss with zero explanation turned out to be two bytes, swapped, in javac's own output. Wildest root cause we've written up in a while. develocity.ai/blog/develocity-found-bug-java-compiler/

Comparing two Build Scans is the fastest way to catch a path-dependent cache miss. Run the build from two locations, diff the task inputs. Usually, it's an absolute path or a volatile input hiding in there.
