我下面的代码抛出以下错误，我可以在 Google 上找到的唯一信息涉及日志记录错误，但没有任何东西看起来像我的。我已经尝试在中央 maven repo 上安装它说需要的依赖项，但问题仍然存在。有谁知道为什么我上课没有发现异常？

import java.io.IOException;
import java.util.concurrent.TimeUnit;

import net.schmizz.sshj.SSHClient;
import net.schmizz.sshj.common.IOUtils;
import net.schmizz.sshj.connection.channel.direct.Session;
import net.schmizz.sshj.connection.channel.direct.Session.Command;

public class ConnectSSH {

public void connecting() throws IOException {

    @SuppressWarnings("resource")
    final SSHClient ssh = new SSHClient();

    ssh.loadKnownHosts();
    ssh.connect("*******");

    try {
        ssh.authPassword("*****", "*****");
        final Session session = ssh.startSession();
        try {
            final Command cmd = session.exec("*****");
            System.out.print(IOUtils.readFully(cmd.getInputStream()));
            cmd.join(5, TimeUnit.SECONDS);
            System.out.print("\n** exit status: " + cmd.getExitStatus());
        } finally {
            session.close();
        }
    } finally {
        ssh.disconnect();

    }

}

}

运行时抛出以下错误：

Exception in thread "main" java.lang.NoClassDefFoundError: net/schmizz/sshj/SSHClient
    at ssh.liq_con.stats.ConnectSSH.connecting(ConnectSSH.java:16)

您实际上不需要安装依赖项 - 它们由 Maven 自动获取。这可能是您的类路径的问题，您可以尝试添加作为您的第一行public static void main(String[])：

System.out.println(System.getProperty("java.class.path"));

确保你sshj-0.9.0.jar在你的类路径中。
