# gradle.properties - Performance tuning

# Enable parallel builds
org.gradle.parallel=true

# Increase Gradle daemon memory
org.gradle.jvmargs=-Xmx4g -XX:MaxMetaspaceSize=1g

# Enable Gradle build cache
org.gradle.caching=true

# Enable configuration cache (used by hot reload optimization)
org.gradle.configuration-cache=true

# Hot Reload optimization (enables config cache during recompilation)
systemProp.compose.reload.gradle.build.optimize=true

// Properties automatically propagated:
// 1. Initial Gradle build sets properties
// 2. Application process receives properties
// 3. Recompiler daemon inherits properties

// Example: Gradle sets java.home
val javaHome = System.getProperty("org.gradle.java.home")

// Hot Reload ensures recompiler uses same JDK
// to avoid cache misses and compatibility issues
