I restarted module but not resolve this. Should this problem come from Ignition version?

[victordcq]

This doesnt look like a problem with ignition but with the build you made. It didnt include the class, did you do a correct import?

[user9]

oh, I don’t know, but I think this is successful build and correct imported.

[victordcq]

Check if this class is in the module file.

And if you have this turned on

NoClassDefFoundError - Trying to add producer to the kafka module

Don’t mistake this answer for me knowing anything about this module because I just cloned it for the first time. I’m not sure what IDE you are using, but in IntelliJ you need to enable this option on your run configuration: [image] All of the Ignition SDK dependencies are marked as “provided” scope in the Maven pom files, which basically means “these are provided by the environment I will run in, so I need them to compile against but don’t need to package them for runtime”.

altho i would think the ignition gateway should have acces to those files anyways, weird

Thank you so much.
I solved this problem when I change scope from ‘provide’ to ‘compile’.

[Kevin.Herron]

You shouldn’t use “compile” for this dependency.

It looks to me like the real problem is the reporting component example is still using the old module ID of the reporting module instead of the new one: com.inductiveautomation.reporting

If you change rept to com.inductiveautomation.reporting in these dependencies it should work…
