bazel - netty_tcnative 错误

【问题标题】：bazel - netty_tcnative errorsbazel - netty_tcnative 错误
【发布时间】：2020-03-19 18:28:56
【问题描述】：

我正在尝试运行由 grpc 提供支持的 java 应用程序，但我需要 netty_tcnative 才能工作。我正在关注一个例子https://github.com/grpc/grpc-java/blob/master/examples/example-tls/BUILD.bazel。到目前为止，我还没有成功地让它工作。我收到这样的错误：

我不确定我做错了什么。任何帮助都会很棒！

【问题讨论】：

  • 我不确定这是不是一个原因，但你不应该同时使用grpc-netty 和grpc-netty-shaded。你能去掉一个试试吗？
  • 嗨@creamsoup，你是对的。我保留了grpc-netty-shaded。问题是我的https://mvnrepository.com/artifact/io.opencensus/opencensus-contrib-grpc-metrics/0.8.0 不够有趣，它在我的maven_install.json 文件中。我需要查看可以在 Maven 中使用的覆盖目标配置。

【解决方案1】：

grpc-java 的 grpc-netty-shaded 目标实际上并没有遮蔽，所以看起来你的 @maven//:io_grpc_* 目标实际上是从 Maven Central 中提取的。您应该改用 grpc-java 存储库目标。

为了适当混合 Maven 依赖项和 Bazel 依赖项，请在您的 WORKSPACE as done in the example 中使用 maven_install 的 override_targets。

maven_install(
    artifacts = IO_GRPC_GRPC_JAVA_ARTIFACTS,
    generate_compat_repositories = True,
    override_targets = IO_GRPC_GRPC_JAVA_OVERRIDE_TARGETS,
    repositories = [
        "https://repo.maven.apache.org/maven2/",
    ],
)
