## ⚠️ DO NOT Upgrade

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

## Quick Start

### 1. Update Version Catalog

```toml
# 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

```bash
./gradlew wrapper --gradle-version=8.14.3
```

### 3. Add JUnit Platform Launcher

Required for Gradle 8.14.3 with JUnit 5.11+:

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

### 4. Update Redis Libraries (if applicable)

Check if project uses Redis:

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

If Redis is used, update:

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

### 5. Validate

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