Lombok Not Generating Getters in Spring Boot with MapStruct & Maven (Java 21)

I'm working on a Spring Boot project and facing an issue where Lombok is not generating getters for my entity class. Despite using @Data or @Getter, the getters are missing at compile time, leading to errors like "cannot find symbol getEmail()". My Setup (Dependencies & Plugins in pom.xml): 
<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <optional>true</optional>  <!-- Tried removing this -->
</dependency>

<dependency>
    <groupId>org.mapstruct</groupId>
    <artifactId>mapstruct</artifactId>
    <version>${org.mapstruct.version}</version>
</dependency>

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>

Tried Solutions from GitHub Issues & Community: ✅ Added -proc:full to <compilerArgs> under maven-compiler-plugin ✅ Removed <optional>true</optional> from Lombok dependency ✅ Enabled annotation processing in IntelliJ/Eclipse settings ✅ Checked for conflicting imports of User class ✅ Rebuilt the project using mvn clean install & mvn clean compile However, Lombok-generated methods are still missing! 💡 Any ideas on what could be causing this issue in my Spring Boot project? 🚀 Hey everyone! I finally figured out why Lombok wasn't generating getters in my Spring Boot project. 🤦‍♂️ Turns out, I forgot to add Lombok as an annotation processor inside annotationProcessorPaths for MapStruct in maven-compiler-plugin. Adding this fixed it: 
<path>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>${org.lombok.version}</version>
</path>
<path>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>${org.lombok.version}</version>
</path>
Hopefully, this saves someone else the headache! 😅🚀
