反序列化pbf编码的文件

Question

我正在使用一个名为SharedStreets-Matcher https://github.com/sharedstreets/sharedstreets-matcher的github项目。它使用Google的protobuf技术生成一个speeds pbf编码文件。

     FileInputStream inputStream = new FileInputStream(s);


    SharedStreetsSpeedsProto.SharedStreetsWeeklySpeeds  speedData  = S haredStreetsSpeedsProto.SharedStreetsWeeklySpeeds.newBuilder().mergeFrom(inputStream).build();

    System.out.println( speedData .getReferenceId());

原始文件就是这个https://github.com/sharedstreets/sharedstreets-ref-system/blob/master/proto/speeds.proto。我在做什么错了？

这是我得到的错误。
