CustomValue Annotation Processing : How can i create a similar annotation of @Value

Question

I have just started using annotation processing and trying to inject the value on the field annotated with my annotation . Since yesterday I am facing this error message: Compilation failure

I have tried to research and fix but unable to avoid this error here is my CustomValueProcessor.java class and my annotation:

@Target(ElementType.FIELD)
@Retention(RetentionPolicy.RUNTIME)
public @interface CustomValue {
    String value(); // This attribute will hold the property value
}

import com.google.auto.service.AutoService;
import report.configurations.PropertyLoader;
import javax.annotation.processing.*;
import javax.lang.model.SourceVersion;
import javax.lang.model.element.Element;
import javax.lang.model.element.ElementKind;
import javax.lang.model.element.TypeElement;
import javax.lang.model.element.VariableElement;
import javax.lang.model.type.TypeMirror;
import javax.tools.Diagnostic;
import java.lang.reflect.Field;
import java.util.Map;
import java.util.Set;

@SupportedAnnotationTypes("report.annotations.CustomValue")
@SupportedSourceVersion(SourceVersion.RELEASE_17)
@AutoService(javax.annotation.processing.Processor.class)
public class CustomValueProcessor extends AbstractProcessor {
    private Messager messager;
    private final Map<String, String> PropMap = PropertyLoader.parsePropertiesFile();

    @Override
    public synchronized void init(ProcessingEnvironment processingEnv) {
        super.init(processingEnv);
        messager = processingEnv.getMessager();
    }

    @Override
    public boolean process(Set<? extends TypeElement> annotations, RoundEnvironment roundEnv) {
        for (TypeElement annotation : annotations) {
            for (Element element : roundEnv.getElementsAnnotatedWith(annotation)) {
                if (element.getKind() == ElementKind.FIELD) {
                    CustomValue annotationValue = element.getAnnotation(CustomValue.class);
                    String newParaName = annotationValue.value().substring(2, annotationValue.value().length() - 1);
                    String propertyValue = PropMap.get(newParaName);
                    //messager.printMessage(Diagnostic.Kind.ERROR, propertyValue);
                    VariableElement fieldElement = (VariableElement) element;
                    String fieldName = fieldElement.getSimpleName().toString();
                    //messager.printMessage(Diagnostic.Kind.ERROR, fieldName);
                    // Get the class type from the TypeElement
                    TypeElement enclosingClass = (TypeElement) fieldElement.getEnclosingElement();
                    TypeMirror classType = enclosingClass.asType();
                    //messager.printMessage(Diagnostic.Kind.ERROR, classType.toString());
                    // Assuming PdfService is in the same package as enclosingClass
                    Class<?> clazz = enclosingClass.getClass();
                    // Get the field
                    try {
                        Field field = clazz.getDeclaredField(fieldName);
                        //messager.printMessage(Diagnostic.Kind.ERROR,field.toString());
                        field.setAccessible(true);
                        // Set the value of the field
                        field.set(null, propertyValue);  // Pass an object instance instead of null if the field is non-static
                    } catch (NoSuchFieldException | IllegalAccessException e) {
                        e.printStackTrace();
                    }
                }
            }
            return false;
        }
        return false;
    }
}

Please suggest/advice what I am doing wrong.
