You can't execute the script directly since it has to be interpreted by a shell like bash. Note that bash is an executeable.
你不能直接执行脚本，因为它必须由像 bash 这样的 shell 解释。请注意，bash 是一个可执行文件。
ProcessBuilder pb = new ProcessBuilder("/bin/bash", "/path/LicenseGen.sh");

I have used JSchextensively for remote login and script executions. I used google Expect4jwith Jschfor executing scripts on remote machines in expect mode(send/wait). Since, you have to execute command one after another, you can try this.
我JSch广泛用于远程登录和脚本执行。我使用google Expect4jwithJsch以期望模式（发送/等待）在远程机器上执行脚本。既然，你必须一个接一个地执行命令，你可以试试这个。
It can also be used for local execution that you require. The only worry is that you need to login (into your local machine) for execution.
它还可以用于您需要的本地执行。 The only worry is that you need to login (into your local machine) for execution.
For jsch, go to http://www.jcraft.com/jsch/
For Expect4j, go to http://code.google.com/p/expect4j/
