Replit performance

Gradle Build Very Slow on Replit

Gradle builds take 2-3 minutes even for small changes. Build process is frustratingly slow.

Replit's shared resources and Gradle's large classpath cause slow compilation.

Common Causes

  1. Gradle daemon not running (restarts each build)
  2. Too many dependencies causing compilation
  3. No parallel compilation enabled
  4. Kotlin compilation slower than Java
  5. Tests run during build (should be separate)

How to Fix It

Set org.gradle.parallel=true and org.gradle.workers.max=4 in gradle.properties. Use --no-daemon for single runs, but enable daemon for repeated builds. Skip tests during build: ./gradlew build -x test. Use build cache: org.gradle.caching=true. Consider splitting into modules to parallelize.
