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
