JSON Payload Generator
vviswadeep opened this issue · comments
I am able to replicate the same exercise for the Hello World,
I'd like to test the same for a JSON Payload,
This is what I tried,
final Counter counter = extensionContext.getMetricRegistry().counter("payloads.generated");
extensionContext.getExtensionRegistry().addPayloadGenerator("hello-world-generator", payloadGeneratorInput -> {
counter.inc();
JSONObject obj=new JSONObject();
obj.put("name","sonoo");
obj.put("age",new Integer(27));
obj.put("salary",new Double(600000));
//System.out.print(obj);
return ByteBuffer.wrap(obj.toString().getBytes(StandardCharsets.UTF_8));
The Jar was build successfully, I pasted the jar in the extension, but I am getting the following error.

Please let me know how to proceed. Thank you
Hi @vviswadeep
You need to package all your dependencies into your extension jar.
You can for example use the shadow Gradle plugin (https://github.com/johnrengelman/shadow) and use the output of the shadowJar task instead of the jar task.
Hope this helps.
