How can I capture the output of the ShellScript in Groovy ?

Hi,

    I am trying to capture the output of the Shell Script by using below pice of code but it is not working for me .

import java.io.InputStream;
import com.jcraft.jsch.ChannelSftp;
import com.jcraft.jsch.Channel;
import com.jcraft.jsch.ChannelExec;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;
import com.jcraft.jsch.SftpException;
import com.jcraft.jsch.*
import java.io.*
import java.lang.*

JSch jsch = new JSch();
Session session = jsch.getSession("admin","192.168.2.32", 22);
session.setPassword("admin123");
java.util.Properties config = new java.util.Properties();
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);
session.connect()
Channel channel = session.openChannel("exec");
channel.connect();
//def command=((ChannelExec)channel).setCommand("bash /home/bedrock/Soapui_Automation/test.sh");
def command = "bash /home/bedrock/Soapui_Automation/test.sh"
def process = command.execute()
def outputStream = new StringBuffer()
def errorStream = new StringBuffer()
process.consumeProcessOutput(outputStream ,errorStream)
process.waitFor()
log.info("return code: ${process.exitValue()}")
log.error("standard error: ${process.err.text}")
log.info("standard out: ${process.in.text}" + outputStream.toString())
channel.disconnect();
session.disconnect();
