为什么jenkins在构建后不能启动java进程

我正在使用此shell脚本启动java进程：

#!/usr/bin/env bash

# 当使用未初始化的变量时，程序自动退出
# 也可以使用命令 set -o nounset
set -u

# 当任何一行命令执行失败时，自动退出脚本
# 也可以使用命令 set -o errexit
set -e

set -x


JAVA_HOME="/usr"
APP_HOME="/Users/dabaidabai/.jenkins/workspace/soa-robot/soa-robot-service/build/libs"
APP_NAME="soa-robot-service-1.0.0-SNAPSHOT.jar"

PID=`ps -ef|grep -w ${APP_NAME}|grep -v grep|cut -c 9-15`
if [[ ${PID} -gt 1 ]]; then
        kill -9 ${PID}
        sleep 5
else
        echo "Process not found"
fi

count=`ps -ef | grep ${APP_NAME} | grep -v "grep" | wc -l`
if [[ ${count} -lt 1 ]]; then
  cd ${APP_HOME}
  nohup ${JAVA_HOME}/bin/java -Xmx440M -Xms128M -jar \
  -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/opt \
  -Xdebug -Xrunjdwp:transport=dt_socket,suspend=n,server=y,address=5009 \
  ${APP_HOME}/${APP_NAME} >> /dev/null &
  sleep 5
else
  echo "process aready exists!"
  exit 1
fi

在jenkins中执行以下脚本：

/bin/bash ${WORKSPACE}/script/upgrade.sh

这是jenkins执行日志输出：

但是，当我登录服务器并发现进程没有启动时，为什么会发生这种情况？当我在服务器的终端中执行此脚本时，它可能会启动进程成功：

nohup /usr/bin/java -Xmx440M -Xms128M -jar -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/opt -Xdebug -Xrunjdwp:transport=dt_socket,suspend=n,server=y,address=5009 /Users/dabaidabai/.jenkins/workspace/soa-robot/soa-robot-service/build/libs//soa-robot-service-1.0.0-SNAPSHOT.jar &

你把

+nohup/usr/bin/java-Xmx440M-Xms128M-jar&&在命令的末尾？成功消息是关于脚本本身，而不是调用的java命令。是的，我在命令的最后一个@thannguyevan中添加了（&D）
