I'm just starting with Talend component kit using Intellij and trying just follow guide how to create first logger component but have an error :

WARNING: An illegal reflective access operation has occurred

Thank you for any help in advance.

Hello,

Your issue comes from this:

java.lang.NoClassDefFoundError: routines/system/Dynamic

Which is fixed in the later version of component kit, so it's enough to build the component with a newer version.

Hi @Balazs Gunics

I'm using TCK version 1.57.1 - is there any newer version ?

Still have the same error. Any idea ?

I have re-installed windows with new Talend DI version 8.0.1.20211109_1610

Just trying simple :

@ElementListener

public void onNext(

@Input final Record defaultInput,

@Output final OutputEmitter<Record> defaultOutput) {

System.out.println("abc");

}

and connecting trowgenerator with my component.

Thank you for your help.
