Target Versions

⚠️ DO NOT Upgrade

• protobuf: Keep existing version (3.x → 4.x is breaking)
• grpc: Keep existing version

Quick Start

1. Update Version Catalog

# gradle/libs.versions.toml
[versions]
springBoot = "3.5.8"
springCloud = "2025.0.0"  # CRITICAL for 3.5.x compatibility
spock = "2.4-groovy-4.0"

[plugins]
spring-boot = { id = "org.springframework.boot", version.ref = "springBoot" }
spring-dependency-management = { id = "io.spring.dependency-management", version = "1.1.7" }

2. Update Gradle Wrapper

./gradlew wrapper --gradle-version=8.14.3

3. Add JUnit Platform Launcher

Required for Gradle 8.14.3 with JUnit 5.11+:

subprojects {
    plugins.withType(JavaPlugin).configureEach {
        dependencies {
            testRuntimeOnly libs.junit.platform.launcher
        }
    }
}

4. Update Redis Libraries (if applicable)

Check if project uses Redis:

grep -r "bitso.commons:redis\|jedis" --include="*.gradle" --include="*.toml" .

If Redis is used, update:

[versions]
bitso-commons-redis = "4.2.1"
jedis4-utils = "3.0.0"

5. Validate

./gradlew clean build -x test
./gradlew test
