Developer Productivity – How I Learned to Stop Worrying and Love the AI
summary
Shows concrete fixes for slow JVM builds: enable Gradle build scans to find tests as the bottleneck, add Mantium embeddings plugin so ChatGPT uses up-to-date Gradle docs, and flip maxParallelForks to use all CPU cores to cut a 60s test run to ~6s. Demonstrates remote caching and CI-populated caches to eliminate first-build slowness, and cites predictive test selection that saves ~30% of build time with ~98.7% failure prediction accuracy.
