我正在尝试编写来自google pub / sub的一些消息。写作大型作品，所以基础层面没有任何遗漏。
我已升级到google-cloud-dataflow-java-sdk-all v2.3.0，其中包括SpannerIO接收器。
我基本上都遵循了API docs of SpannerIO的写作示例。
但是，我收到异常internal_static_google_rpc_LocalizedMessage_fieldAccessorTable

指定withProjectId()无法解决问题。
也没有升级所有依赖项，包括传递中的依赖项 - 除非我犯了错误（我不习惯数据流在内部的结构以及每个依赖项的作用）。更新依赖项之后，甚至没有暂存已编译的项目。
我怀疑存在需要更新的特定依赖关系，我尝试了各种组合，但无济于事。
更新
我尝试过的其中一件事就是将grpc-google-common-protos固定在0.1.9或甚至是最新的1.2.0。
如果我这样做，甚至没有上传管道，因为我在上传之前得到以下例外：

看看这个Stack Overflow帖子：Error using SpannerIO in apache beam。它可能与JIRA问题BEAM-2837中描述的相关或相同的问题有关。
Stack Overflow帖子没有接受的答案，但我能够通过明确定义所需的com.google.api.grpc依赖关系并从org.apache.beam中排除版本来解决问题。
<dependency>
<groupId>com.google.api.grpc</groupId>

答案 1 :(得分：0)
如果您使用的是gradle，请使用以下代码段来强制执行该版本。这解决了我的问题。
compile (group: 'com.google.api-client', name: 'google-api-client', version: '1.22.0') {
force = true
}
