Question

使用Google Cloud Platform服务开发maven spring启动应用程序，包括同一应用程序中的BigQuery，PubSub和Dataflow / Beam。

我通过maven添加了以下依赖项：

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-gcp-starter-pubsub</artifactId>
    </dependency>

    <dependency>
        <groupId>org.apache.beam</groupId>
        <artifactId>beam-sdks-java-core</artifactId>
        <version>2.2.0</version>
    </dependency>

    <dependency>
        <groupId>com.google.cloud</groupId>
        <artifactId>google-cloud-bigquery</artifactId>
        <version>0.33.0-beta</version>
    </dependency>

    <dependency>
        <groupId>org.apache.beam</groupId>
        <artifactId>beam-runners-google-cloud-dataflow-java</artifactId>
        <version>2.2.0</version>
    </dependency>

问题是当应用程序运行时，抛出以下异常：

在上下文初始化期间遇到异常 - 取消刷新尝试：org.springframework.beans.factory.UnsatisfiedDependencyException：在类路径资源中定义名称为'pubSubAdmin'的bean时出错[org / springframework / cloud / gcp / pubsub / autoconfig / GcpPubSubAutoConfiguration .class]：通过方法'pubSubAdmin'参数0表示的不满意的依赖;嵌套异常是org.springframework.beans.factory.BeanCreationException：在类路径资源中定义名称为'topicAdminClient'的bean时出错[org / springframework / cloud / gcp / pubsub / autoconfig / GcpPubSubAutoConfiguration.class]：通过工厂方法进行Bean实例化失败;嵌套异常是org.springframework.beans.BeanInstantiationException：无法实例化[com.google.cloud.pubsub.v1.TopicAdminClient]：工厂方法'topicAdminClient'抛出异常;嵌套异常是java.lang.NoClassDefFoundError：com / google / api / gax / grpc / GrpcStatusCode

根据João André Martins建议的更改，出现了另一个异常：

我能够使用你的pom.xml，spring-cloud-gcp版本1.0.0.M2编译一个类似的项目，并对你的依赖项进行以下更改。

希望这有帮助！

    <dependency>
        <groupId>io.grpc</groupId>
        <artifactId>grpc-core</artifactId>
        <version>1.9.0</version>
    </dependency>

    <dependency>
        <groupId>io.grpc</groupId>
        <artifactId>grpc-netty</artifactId>
        <version>1.9.0</version>
    </dependency>

    <dependency>
        <groupId>org.apache.beam</groupId>
