[Python] JavaEE project update package packaging tool, pythonjavaee

The only Python script recommended by someone has been clicked. Well, should I issue some ready-made script tools?

 

First, let's talk about the production environment of this item.

People are in outsourcing companies, and there is no such thing as a small scale.

After the Java Web project is deployed, you must update the code and manually copy the changed file to the server to replace it. In particular, If you change a bunch of bugs to Java, when JSP files are dozens or even more... it is quite painful to manually find the compiled class from Tomcat.

But I also said that there are no specifications, and there are no ready-made tools... As a result, I want to write a script to automatically package it.

 

The Enterprise project is mainly Eclipse + SVN, and SVN uses sqlite3 as the local data storage to store the file change list. Then SVN can be used to conveniently and quickly obtain file update information.

Because the project file structures of different ides are different, this script can only be used for applications in the same environment (Eclipse + SVN ).

The usage is very simple. Enter the SVN project directory/package start version/Tomcat application directory/generate a different directory as prompted, the system will automatically read all file changes from the SVN version to the last version, and go to Tomcat to find the corresponding file (class/jsp, etc ), copy the file to the corresponding location of the generated differential directory. At last, you only need to back up the original application, paste and replace the entire folder, and restart the file.

I have never learned anything about Python. Just ignore the variable name and specification ....
