Python3 automated deployment of javaweb systems to remote Tomcat

Just learn python recently, do not want to do something ....

Made an automated deployment of the script, shortcoming.

The following hypothetical database is used together with

The process is as follows:

Local maven Package
upload to Server
Server database library backup
server shutdown Tomcat
Server application backup
Server purge application, work
server boot tomcat
