Spring MQTT：java.util.MissingResourceException：找不到基本名称的包org.eclipse.paho.client.mqttv3.internal.nls.logcat，locale en_US

Question

注意：我是 不 运行eclipse。我正在使用maven从命令行运行一个独立的Spring应用程序。

当我尝试使用spring-integration-mqtt 4.3.8向使用IoC创建的出站通道适配器发送消息时，我得到了

这表明我错过了依赖，但我不知道它可能是什么。

也许你的maven回购中有一个腐败的罐子？显然你有org.eclipse.paho.client.mqttv3.logging.LoggerFactory类;我在jar中看到了logcat包...
