I follow the readme and get an error like this 2020-03-20 21:57:45,712 INFO o.j.g.c.GrpcClientSampler: grpcCallMethod 2020-03-20 21:57:45,712 ERROR o.j.g.c.GrpcClientSampler: grpcCallMethod Exception java.lang.NoSuchMethodException: greet.GreeterGrpc$GreeterBlockingStub.SayHello(greet.HelloRequest) how can I fix this?

Can you give me your .proto and .jmx files? For the error is displayed, I can guess some problem can happen:

The method must begin by lowercase: example sayHello but not SayHello
Is your package in the .proto only named greet ?

I follow command: apache-jmeter-5.2/bin/jmeter.sh -n -t GrpcClientSampler.jmx -l result.csv Picked up _JAVA_OPTIONS: -Xmx4096m Error in NonGUIDriver java.lang.NullPointerException An error occurred: Error in NonGUIDriver null How can I fix this error ?

Hello @datuanmac, before you run that command, please ensure : 1) The dependency jmeter-grpc-client-sampler.jar is coppied into apache-jmeter-5.2/lib/ext 2) The *.jar file after build *.proto file is also in apache-jmeter-5.2/lib/ext
