NoSuchMethodError:io.netty.handler.codec.http.HttpResponseStatus.codeAsText()Lio/netty/util/AsciiStr

I am using java 1.8 and trying to connect my java grpc-client to ruby grpc server using grpc (1.3.0.0)

but at the time of execution it's giving me following exeption:

java.lang.NoSuchMethodError: io.netty.handler.codec.http.HttpResponseStatus.codeAsText()Lio/netty/util/AsciiString;

Note: grpc server is implemented in c-ruby.

thank you in advance!

Do you know what version of gRPC Java you are using?  Is it possible you are depending on two different versions of Netty?

I am using grpc version 1.3.0 can you help me out how to solve this problem.?

[Carl Mastrangelo]

It seems like you may have two copies of netty in your code.  If you are using gradle, can you print out the dependencies of your project?  It should come out of something like:

./gradlew :dependencies

You're using a different/wrong version of Netty. grpc-java is quite particular about the version of Netty being used and needs exactly what its dependency specifies.

Eventually we'll have a pre-shaded Netty transport that should avoid most versioning issues.
