Question

我正在使用protobuf玩榛子和grpc。我已经按照在线指南和教程创建了一个简单的问候应用程序。使用mvn exec:java，可以使用我的IDE正常运行。但是，当我尝试运行由bazel build命令生成的二进制文件时，在运行时会得到以下信息

bazel-bin/greet_client

stacktrace似乎指向opencensus相关的jar。

我检查的第一件事是我是否具有不同版本的依赖关系，并且在maven pom.xml和为bazel生成的依赖关系之间似乎没有什么区别。

当我将grpc的版本从1.18.0降级到1.17.1时，它没有问题。

我对bazel的依赖性

#dependencies.yml
dependencies:
  io.grpc:
    grpc:
      modules: ["protobuf", "stub", "netty-shaded"]
      version: "1.18.0"
      lang: java

我的pom.xml

<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <grpc.version>1.18.0</grpc.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>io.grpc</groupId>
            <artifactId>grpc-netty-shaded</artifactId>
            <version>${grpc.version}</version>
        </dependency>
        <dependency>
            <groupId>io.grpc</groupId>
            <artifactId>grpc-protobuf</artifactId>
            <version>${grpc.version}</version>
        </dependency>
        <dependency>
            <groupId>io.grpc</groupId>
            <artifactId>grpc-stub</artifactId>
            <version>${grpc.version}</version>
        </dependency>
    </dependencies>

bazel运行在CensusStatsModule处给出java.lang.NoSuchFieldError
