Java 远程执行linux命令

需求：java代码中远程执行linux的pyton 命令和 shell命令

java远程执行linux命令对应的pom.xml 为：

<dependency>
    <groupId>ch.ethz.ganymed</groupId>
    <artifactId>ganymed-ssh2</artifactId>
    <version>262</version>
</dependency>

代码部分如下：

import ch.ethz.ssh2.Connection;
import ch.ethz.ssh2.Session;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

        RemoteSubmitCommand(remoteCommand);
        submitModelDataSync(localCommand);
    }
