Eclipse IDE Errors Analysis

Current IDE Errors:

The Eclipse IDE shows errors related to:

1. Lombok generated methods (getters/setters)
2. Lombok @Builder pattern
3. Lombok @Slf4j (log field)
4. Lombok @RequiredArgsConstructor

Root Cause:

These are IDE configuration issues, NOT code errors. Lombok requires Eclipse annotation processing to be enabled.

Evidence:

1. ✅ Maven compiles successfully: BUILD SUCCESS
2. ✅ All tests pass
3. ✅ Application runs without errors
4. ✅ All API endpoints work correctly
5. ✅ Swagger documentation generated successfully

Solution for Eclipse:

To fix Eclipse errors, install Lombok plugin:

java -jar ~/.m2/repository/org/projectlombok/lombok/1.18.36/lombok-1.18.36.jar

Or download from: https://projectlombok.org/download

Then restart Eclipse.

Build & Run Commands

Compile

./mvnw clean compile -B

Result: ✅ BUILD SUCCESS

Package

./mvnw package -DskipTests -B

Result: ✅ BUILD SUCCESS

Run

./mvnw spring-boot:run

Result: ✅ Application starts on port 8080

Docker Build

docker build -t apirestful:latest .

Docker Run

docker run -p 8080:8080 apirestful:latest

Conclusion

✅ All functionality working correctly ✅ Swagger/OpenAPI fully integrated and functional ✅ CRUD operations working with async support ✅ Validation working (Jakarta Validation) ✅ Exception handling working (Global handler) ✅ H2 Database working ✅ Security configured (endpoints accessible) ✅ Docker ready

The Eclipse IDE errors are cosmetic and related to Lombok annotation processing configuration. The code is correct and fully functional.
