反序列化protobuf消息时发生java.lang.NoClassDefFoundError

我在数据流作业中使用protobuf生成的java类来处理消息。我一直在尝试运行一些东西，但是依赖项（jar-hell）存在一些问题，导致反序列化失败，出现以下异常：

我在gradle项目中使用以下依赖项：

compile 'com.google.cloud.dataflow:google-cloud-dataflow-java-sdk-all:1.5.0'
compile 'com.google.protobuf:protobuf-java:3.0.0-beta-2'
compile 'io.grpc:grpc-all:0.13.2'

protobuf文件是使用以下配置编译的（使用gradle protobuf插件）

更新

找到了另一个可能有用的堆栈跟踪：
