Jitpack is a unique package repository for JVM and Android projects, designed to simplify the process of building and distributing GitHub-hosted Java and Android packages. By converting GitHub repositories directly into usable packages, Jitpack eliminates the need for project maintainers to create and host their own build artifacts, making it easier for developers to integrate third-party libraries into their projects. The service supports various build tools including Maven and Gradle, and automatically builds projects upon request, providing immediate access to libraries.
