CI/CD for a Slow Gradle Build: Cut the Wait
A cold Gradle build with no cache and a memory-starved daemon can take 15 minutes - on every push.
Gradle CI is slow when caches are cold and the daemon is under-resourced. Caching and right-sized memory fix most of it.
Cache the Gradle caches
Cache ~/.gradle/caches and the wrapper so dependency resolution and compiled output are reused across runs.
Right-size the daemon
Gradle OOMs and slows when starved. Managed runners let you pick a size with enough heap without paying premium rates.
Cheaper compute
Gradle builds benefit from more cores and memory. Managed runners deliver that at about 69 percent lower cost than GitHub-hosted.
Recover transient OOM
Self-healing retries daemon OOM and transient failures so a one-off crash does not cost a full manual re-run.
Key takeaways
- Cache ~/.gradle/caches and the wrapper.
- Right-size daemon memory.
- About 69 percent cheaper; auto-retry OOM crashes.
