I'm also facing this issue, both with external proto files as well as my internal ones. It'd be very helpful if you could update the ticket with the fix.

 

Cheers

>          Components: java

> Using avro-protobuf for google protobuf timestamp models fails to extract schema due to invalid namespace resolution.
>   
>  Proto model for timestamp has following options defined. 
> {code:java}
> option java_outer_classname = "TimestampProto";
> option java_multiple_files = true; 
> {code}
>  
>  That would mean that the generated code for Timestamp will be at "com.google.protobuf.Timestamp" rather than "com.google.protobuf.TimestampProto$Timestamp". 
>   
>  However, when I try to derive an avro schema from a proto model using google timestamp, avro-protobuf is not honouring the java_multiple_files option and tries to look for timestamp class at "com.google.protobuf.TimestampProto$Timestamp"
>   
> {code:java}
> Caused by: java.lang.ClassNotFoundException: Failed to load classcom.google.protobuf.TimestampProto$Timestamp
>  at org.apache.avro.util.ClassUtils.forName(ClassUtils.java:60)
>  at org.apache.avro.util.ClassUtils.forName(ClassUtils.java:36)
>  at org.apache.avro.protobuf.ProtobufData.newRecord(ProtobufData.java:137){code}
>  
>  "getNamespace" of org.apache.avro.protobuf.ProtobufData ins't honouring multiple files option there by breaking models that import google proto definitions.
