Spring MQTT: java.util.MissingResourceException: C

Question

NOTE WELL: I am NOT running eclipse. I am running a standalone Spring application from the command line with maven.

When I attempt to send a message to an outbound channel adapter created with IoC using spring-integration-mqtt 4.3.8, I get

This suggests I am missing a dependency, but I have no idea what it might be.

Answer 1

Perhaps a corrupt jar in your maven repo? Clearly you have the org.eclipse.paho.client.mqttv3.logging.LoggerFactory class; I see the logcat bundle in my jar...
