Did all these things

• Added Lombok dependency in pom.xml.
• Verified Lombok is present in mvn dependency:tree.
• Installed the Lombok plugin in IntelliJ IDEA.
• Restarted IntelliJ after installing the plugin.
• Enabled annotation processing in IntelliJ settings.
• Annotated the service class with @RequiredArgsConstructor.
• Rebuilt the project using IntelliJ’s Rebuild Project.
• Ran mvn clean compile from the terminal.
• Checked IntelliJ Alt + 7 Structure tab to confirm constructor generation.
• Validated Lombok dependency version is compatible with Java 17.
• Used Invalidate Caches / Restart in IntelliJ.
• Confirmed manually written constructor works, but Lombok-generated one doesn’t show effect.
