The base path within the repository where the library files are located.

Expected Structure:

• vars/ - Global variables and functions (e.g., vars/uploadToGooglePlay.groovy)
• src/ - Shared classes (optional)
• resources/ - Resource files (optional)

Examples:

• Meta/Jenkins/SharedLib - If your library is at Meta/Jenkins/SharedLib/vars/
• jenkins-lib - If your library is at repository root jenkins-lib/vars/
• . or leave empty - If vars/ is at repository root

Jenkins will look for vars/, src/, and resources/ directories within this base path.
