How to use this and what is the purpose of this script?

Hi again @mydearmuthu1978

This script is also to be run in the Jenkins script console.

From line 1 to 6 are imports of the classes that the script will use.

In line 8 there is the variable that contains the name you want to use to register your shared library.

In line 9 is the address of the GIT repository where your shared library is.

In line 11 there is a condition that the installation code will only be executed if the shared library is not installed.

In line 12 I get all shared libraries already registered with Jenkins.

In lines 13 and 14 I initialize a class that is responsible for git information.

In lines 15 to 19 I initialize the class responsible for configuring the shared library.

In line 20 added this new library to the list of existing libraries.

From line 21 to 13 I save this new shared library.

Thank you so much Marcos
