Conflicts with plugin rollno748/Jmeter-pubsub-sampler

[kuboraam]

I am currently using rollno748/Jmeter-pubsub-sampler to send requests to Pub/Sub and this works well. However, If i have both plugins - rollno748/Jmeter-pubsub-sampler and rollno748/di-kafkameter installed, and I run the same pub/sub test plan, JMeter throws the following stacktrace:

java.lang.NoSuchMethodError: 'void com.google.common.base.Preconditions.checkArgument(boolean, java.lang.String, int)' at com.google.api.gax.grpc.InstantiatingGrpcChannelProvider$Builder.setPoolSize(InstantiatingGrpcChannelProvider.java:553) ~[jmeter-pubsub-sampler-1.1.jar:?] at com.google.api.gax.grpc.InstantiatingGrpcChannelProvider$Builder.setChannelsPerCpu(InstantiatingGrpcChannelProvider.java:572) ~[jmeter-pubsub-sampler-1.1.jar:?] at com.google.api.gax.grpc.InstantiatingGrpcChannelProvider$Builder.setChannelsPerCpu(InstantiatingGrpcChannelProvider.java:561) ~[jmeter-pubsub-sampler-1.1.jar:?] at com.google.cloud.pubsub.v1.Publisher$Builder.<init>(Publisher.java:700) ~[jmeter-pubsub-sampler-1.1.jar:?] at com.google.cloud.pubsub.v1.Publisher$Builder.<init>(Publisher.java:651) ~[jmeter-pubsub-sampler-1.1.jar:?] at com.google.cloud.pubsub.v1.Publisher.newBuilder(Publisher.java:647) ~[jmeter-pubsub-sampler-1.1.jar:?] at com.google.cloud.pubsub.v1.Publisher.newBuilder(Publisher.java:626) ~[jmeter-pubsub-sampler-1.1.jar:?] at com.di.jmeter.pubsub.config.PublisherConfig.testStarted(PublisherConfig.java:97) ~[jmeter-pubsub-sampler-1.1.jar:?] at org.apache.jmeter.engine.StandardJMeterEngine.notifyTestListenersOfStart(StandardJMeterEngine.java:218) ~[ApacheJMeter_core.jar:5.5] at org.apache.jmeter.engine.StandardJMeterEngine.run(StandardJMeterEngine.java:396) ~[ApacheJMeter_core.jar:5.5] at java.lang.Thread.run(Thread.java:833) ~[?:?]

Can you please share the complete jmeter.log and a sample test plan structure of yours ? I have used both di-kafkameter and pubsub plugin together - haven't faced this. But there is a possibility of error which might be due to the fatty jar which I am building for di-kafkameter

Hi, please see attached the full jmeter.log and the sample test plan.

Thanks for sharing this - I will take a look at the attached files and push a change if required.

[rollno748]

Alright ! - the issue is due to the pub-sub plugin jar compiled as a shaded jar I will try to create a release to have its Transient dependencies separately

[kuboraam]

thank you for the prompt response :)

[rollno748]

Removed the fatty jar in this new version -1.1 This should avoid the conflicts with Pubsub plugin

[rollno748]

I will close this after releasing this version to plugins manager soon

[rollno748]

The newer version of di-kafkameter is out in plugins manager I am closing this ticket - If you experience the issue again, feel free to re-open it.

Wanna Appreciate it - Hit a star to the repo, It means a lot !

Thanks for your support!
