As the help text clearly states

-r Use this JKS format keystore to verify the server

You need to generate Java KeyStores from the files you have.

Since you don't appear to have any client certs/keys we will assume you are just trying to verify the brokers certificate is issued by a trusted CA. So you will need to add the CA cert to a JKS and pass it with the -r option.

QUESTION

ClassNotFoundException When running jar file but runs fine in Intellij

Asked 2021-Mar-15 at 00:17

I created a small mqtt application using eclipse paho mqtt library in kotlin with Gradle in Intellij IDE. it runs fine when running it through Intellij but when I build it and run the jar file that gets created I get a NoClassDefFoundError error.

From other questions I have seen about this it looks like it has something to do with the class path but I am not sure what needs to be done if that is indeed the issue because I am using gradle and not jar files for libraries.

I was following this tutorial

Here is my gradle file

The way you start your application does not include the dependencies, meaning your MQTT driver and the Kotlin dependencies are not included.

Install paho.mqtt.java

The included code below is a very basic sample that connects to a server and publishes a message using the MQTTv3 synchronous API. More extensive samples demonstrating the use of the MQTTv3 and MQTTv5 Asynchronous API can be found in the org.eclipse.paho.sample directory of the source.
