linux调好了代码，配好了依赖，并写好了 shell 启动脚本。测试成功 。
之后通过windows 的idea 写java 调用 linux 上 shell 脚本执行程序 报错信息如下：

Exception in thread "main" java.lang.UnsupportedClassVersionError: com/boco/querymr/task/ActiveDomainDriver : Unsupported major.minor version 52.0at java.lang.ClassLoader.defineClass1(Native Method)at java.lang.ClassLoader.defineClass(ClassLoader.java:803)at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142)at java.net.URLClassLoader.defineClass(URLClassLoader.java:449)at java.net.URLClassLoader.access$100(URLClassLoader.java:71)at java.net.URLClassLoader$1.run(URLClassLoader.java:361)at java.net.URLClassLoader$1.run(URLClassLoader.java:355)at java.security.AccessController.doPrivileged(Native Method)at java.net.URLClassLoader.findClass(URLClassLoader.java:354)at java.lang.ClassLoader.loadClass(ClassLoader.java:425)at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308)at java.lang.ClassLoader.loadClass(ClassLoader.java:358)at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:482)

网上百度说是jdk版本的问题，发现无论本地 还是linux的java 环境 都是jdk1.8.
各种百度，不禁怀疑人生。后来偶然使用了sudo 命令 这时发现java 的版本突然编程了1.7
这时执行linux上的程序，爆出了相同的问题。
看来应该是 调用ssh 远程连接， 执行shell 时 的用户环境的问题。
解决方式:给程序指定jdk
程序包中放置 jdk目录
运行jar 包时，指定jdk

export PLFMS_JDK_PATH=$BUTLERSYS_PATH/jdk1.8.0_211
$PLFMS_JDK_PATH/bin/java     com.bdpp.monitor.server.start.StartHttpServer

同时附上ssh工具类
