Dialogflow V2 Springboot API调用失败，并出现java.lang.ClassNotFoundException：org / eclipse / jetty / alpn / ALPN

Question

我已经将Dialogflow V2 API（DetectIntend）与Springboot集成在一起，并且在我的本地计算机上运行良好。但是，将API调用部署到GCP后失败。在进行了一些研究之后，我添加了以下依存关系，但两者均无济于事。已通过此处https://github.com/grpc/grpc-java/blob/master/SECURITY.md的指导，但没有解决问题。

<dependency>
        <groupId>io.grpc</groupId>
        <artifactId>grpc-netty-shaded</artifactId>
        <version>1.18.0</version>
    </dependency>
    <dependency>
        <groupId>io.netty</groupId>

        <artifactId>netty-tcnative-boringssl-static</artifactId>
        <version>2.0.20.Final</version>
    </dependency>

请参阅以下堆栈异常。
