| Component | Version | Notes |

|-----------|---------|-------|

| Spring Boot | 3.5.9 | Latest (min 3.5.9) - preparing for Spring Boot 4 |

| Spring Cloud | 2025.0.0 | Required for Spring Boot 3.5.x |

| Spring Dependency Management | 1.1.7 | Required plugin version |

| Gradle | 9.2.1 | Recommended for all projects |

| JUnit | 5.14.2 | Testing (via BOM) |

| Spock | 2.4-groovy-4.0 | Groovy testing (use -groovy-5.0 for Java 25) |

| JaCoCo | 0.8.14 | Code coverage |

| SonarQube Plugin | 7.2.2.6593 | Code analysis |

| bitso-rds-iam-authn | 2.0.0 | If using RDS IAM |

| bitso-commons-redis | 4.2.1 | If using Redis |

CRITICAL: Ensure Spring Boot version is defined in only ONE place.

See [version-centralization.md](../dependency-management/references/version-centralization.md) for details on avoiding multiple version definitions.

1. Update Version Catalog

```toml

# gradle/libs.versions.toml

[versions]

springBoot = "3.5.9"

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=9.2.1

```

3. Add JUnit Platform Launcher

Required for Gradle 9.x 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

```
