Tech Stack
| Component | Version | Notes |
|---|---|---|
| Java | 21 (LTS) | Current LTS version |
| Gradle | 9.2.1 | Recommended for all projects |
| Spring Boot | 3.5.9 | Latest (min 3.5.9) - preparing for Spring Boot 4 |
| Database Access | jOOQ | For accessing PostgreSQL |
| Databases | PostgreSQL, Redis | Primary data stores |
| Inter-service Communication | gRPC | Standard protocol |
| Object Mapping | MapStruct | For DTO/domain mapping |
For Spring Boot upgrades, use /upgrade-to-recommended-versions.
Project Organization
Projects should be organized with domain-based modules:
root-project/
├── build.gradle
├── settings.gradle
├── docs/ # Documentation
├── bitso-libs/ # Library modules
│ ├── <subdomain>/ # Domain logic
│ └── <subdomain-proto>/ # Protobuf definitions
└── bitso-services/ # Service modules
└── <domain>/ # Spring Boot application
Build Verification
After updating Java or Groovy code, verify changes:
# Run tests to verify changes
./gradlew test 2>&1 | grep -E "FAILED|Error" || echo "All tests passed"
# Or run full build with tests
./gradlew build 2>&1 | grep -E "FAILED|Error" || echo "Build successful"
If problems are found, fix them before committing.
