1. Use a repository like GitHub Packages, Nexus Repository Manager, or JFrog Artifactory to store your jar file.
2. Automate the process of uploading the jar file to the artifact repo whenever there is a version update using CI/CD tools like Jenkins
3. Finally, share the repo details with team so that they can include the configuration in their Maven pom.xml files

This way your team can pull required/latest version from repo.
