当我部署我的 jar 在gcp云函数文件中，我得到以下异常

2021-03-11T17:30:04.835Zarun-function-http Exception in thread "main" java.lang.RuntimeException: Class com.arun.serverless.CloudFunctionMain does not implement com.google.cloud.functions.HttpFunction at com.google.cloud.functions.invoker.HttpFunctionExecutor.forClass(HttpFunctionExecutor.java:47) at com.google.cloud.functions.invoker.runner.Invoker.startServer(Invoker.java:252) at com.google.cloud.functions.invoker.runner.Invoker.main(Invoker.java:127)
Exception in thread "main" java.lang.RuntimeException: Class com.arun.serverless.CloudFunctionMain does not implement com.google.cloud.functions.HttpFunction at com.google.cloud.functions.invoker.HttpFunctionExecutor.forClass(HttpFunctionExecutor.java:47) at com.google.cloud.functions.invoker.runner.Invoker.startServer(Invoker.java:252) at com.google.cloud.functions.invoker.runner.Invoker.main(Invoker.java:127)

这是我在cli中遇到的另一个错误

ERROR: (gcloud.alpha.functions.deploy) OperationError: code=3, message=Build failed: build succeeded but did not produce the class "org.springframework.cloud.function.adapter.gcp.GcfJarLauncher" specified as the function target: Error: class not found: org.springframework.cloud.function.adapter.gcp.GcfJarLauncher; Error ID: d818fd83

这是我的源代码
这是我 Spring 的主要课程

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class CloudFunctionMain {

    public static void main(String[] args) {
        SpringApplication.run(CloudFunctionMain.class, args);
    }

}

这是我的职责

import java.util.function.Function;

public class ReverseString implements Function<String, String> {

    @Override
    public String apply(String actualString) {
        return "The reversed string is " + new StringBuilder(actualString).reverse().toString();
    }
}

这是我的梦想 build.gradle 包含

plugins {
    id 'java'
}

group 'com.arun'
//version '1.0'

repositories {
    mavenRepository()
}

dependencies {
    implementation 'org.springframework.cloud:spring-cloud-function-adapter-gcp:3.1.1'
    implementation 'org.springframework.cloud:spring-cloud-starter-function-web:3.1.1'
}

它在我的地方工作得很好。。。但是，当我在gcp云函数中部署时，它并没有开始和停止，只是我在上面粘贴了一个例外
