如何创建由gradle预编译运行的批注处理器，以便向方法中添加代码？

plugins {
    id 'java'
}

dependencies {
    implementation 'javax.annotation:javax.annotation-api:1.3.2'
    annotationProcessor 'com.google.auto.service:auto-service:1.0-rc7'
}

sourceSets {
    main {
        java {
            srcDirs = ['src/main/java']
        }
    }
}

configurations {
    apt
}

compileJava {
    options.compilerArgs += ['-Xplugin:MyAnnotationProcessor']
    options.annotationProcessorPath = configurations.apt
}

task generateSources(type: JavaCompile, group: 'build') {
    source = sourceSets.main.java
    classpath = configurations.compileClasspath
    destinationDir = file('build/generated')
    options.annotationProcessorGeneratedSourcesDirectory = file('build/generated')
}

compileJava.dependsOn generateSources

clean.doLast {
    file('build/generated').deleteDir()
}

import javax.annotation.processing.*;
import javax.lang.model.SourceVersion;
import javax.lang.model.element.TypeElement;
import javax.tools.Diagnostic;

@SupportedAnnotationTypes("com.example.MyAnnotation")
@SupportedSourceVersion(SourceVersion.RELEASE_8)
public class MyAnnotationProcessor extends AbstractProcessor {

    @Override
    public boolean process(Set<? extends TypeElement> annotations, RoundEnvironment roundEnv) {
        for (TypeElement annotation : annotations) {
            for (Element element : roundEnv.getElementsAnnotatedWith(annotation)) {
                processingEnv.getMessager().printMessage(Diagnostic.Kind.NOTE, "Processing element: " + element.toString());
                // 在这里可以添加你的代码逻辑，向方法中添加代码
            }
        }
        return true;
    }
}

import com.example.MyAnnotation;

public class MyClass {

    @MyAnnotation
    public void myMethod() {
        // 这是一个示例方法
    }
}

gradle clean build
