Java 找不到类com.cisco.sdp.vsn.node.channel.tcp.handler.sftp.TestSftpServerHandlerIntegration

当我运行这个类时，它会这样说：我们如何解决这个问题？

类是否没有找到一个非常清晰的错误消息？包含测试类的包是什么？包com.cisco.sdp.vsn.node.channel.tcp.handler.sftp；和类名TestSftpServerHandlerIntegration.java sir，但类存在于我的项目中为什么会出现此错误并编译该类，如果它是maven项目，只需更新它。我已经重新编译了，但仍然存在
