我将采取以下步骤：

git克隆 cd org.eclipse.paho.mqtt.java.git mvn包-DskipTests 此步骤将导致：

有人能帮我吗？

你可以尝试将maven从2.x升级到3.x。

注意，在Ubuntu上，“maven”包比“maven2”包更新。以下命令为我修复了它：

sudo apt-get remove maven2
sudo apt-get install maven

是的@Que，这就是答案，我很久以前就知道了，但是忘了更新帖子。非常感谢。

sudo apt-get remove maven2
sudo apt-get install maven
