Subject: [PATCH 1/2] Fix Java version compatibility and Lombok configuration

- Update Java version from 1.8 to 11 for better compatibility
- Add explicit Lombok version and annotation processor configuration
- Update Maven compiler plugin configuration for Java 11
- This resolves build failures with newer Java versions (Java 17+, 21+, 23+)

+**Recommended Java versions:**
+- Java 11 (LTS) - Fully supported
+- Java 17 (LTS) - Supported  
+- Java 21 (LTS) - Supported

+# Troubleshooting
+
+## Build Issues
+
+### Maven Build Errors with Lombok
+If you encounter compilation errors like "cannot find symbol" for getter/setter methods, this is typically a Java version compatibility issue with Lombok annotation processing.
+
+**Solution**: Ensure you're using Java 11 or higher. The project has been updated to use Java 11 with proper Lombok configuration.
+
+**Check your Java version:**
+```shell
+java --version
+```
+
+**If using Java 23+ and still encountering issues:**
+- Use Java 11 for building (as suggested by community feedback)
+- Or ensure your IDE has the latest Lombok plugin installed
+
+### Docker Build Issues on Apple Silicon (M1/M2)
+If you encounter Docker build failures on Apple Silicon Macs, this is due to architecture compatibility issues with the Docker Maven plugin.
+
+**Solution**: The project includes updated Docker plugin configuration that's compatible with Apple Silicon.
