Eclipse JethroJDBC DriverManager.getConnection在运行带有Dependencies.jar的Maven Snapshot时引发NullPointerException

JethroJDBC

DriverManager.getConnection

在Eclipse IDE中本地运行程序时工作正常，但在运行带有Dependencies.jar的Maven Snapshot时抛出的代码是相同的

NullPointerException

。在可执行jar中，我可以看到类存在于com.jethrodata包中。 请帮帮我

HOST="jdbc:JethroData://UATSERVERHOST:9111/UATINSTANCE"

USER= "USERNAME"

PASS= "PassWord"
