How to set extension for a liquibase installed on CentOS?

General Discussion

Hi All,

I have liquibase installed on CentOS, but I have got very old scripts created for version 1.9, so, they need modifyColumn tag to run.

I found that there is an extension for liquibase version 3.1 and elder which can add this functionality.

https://github.com/liquibase/liquibase-modify-column/wiki

But I cannot figure out how to install this extension to my liquibase.

On my CetOS it is intalled as a jar file, so I cant put the extension jar to it.

When I put this jar as a set_classpath value it does not work.

Could you help me with this problem?
