A Clojure wrapper for JGit providing a functional interface to manipulate Git repositories programmatically.
clj-jgit is a Clojure library that provides a wrapper around the JGit Java library, allowing developers to programmatically manipulate Git repositories from Clojure code. It offers a functional API for common Git operations like cloning, committing, branching, and diffing, serving as a pure-Java alternative to shelling out to command-line Git.
Clojure developers who need to integrate Git operations into their applications, such as building tools for repository automation, CI/CD pipelines, or version-controlled data management.
Developers choose clj-jgit because it provides an idiomatic, functional Clojure interface to JGit, reducing boilerplate and making Git operations more composable compared to using JGit directly or invoking shell commands.

Provides a functional, composable interface that aligns with Clojure idioms, making Git operations like cloning and committing more natural compared to JGit's imperative Java API, as highlighted in the philosophy section.
Supports multiple authentication methods including SSH keys, passwords, and GPG signing with macros like `with-credentials`, allowing secure remote operations without shelling out.
Covers common tasks such as cloning, branching, committing, diffing, and blaming through functions like `git-clone` and `git-diff`, with detailed examples in the quickstart tutorial.
Eliminates the need to invoke command-line Git, reducing external process overhead and improving reliability in pure-Java environments, as stated in the value proposition.
Primarily wraps JGit's porcelain API, with the README admitting that lower-level functions may not be fully covered, potentially restricting advanced Git manipulations.
Requires Java 11 or newer since version 1.0.2, which can be a barrier for projects stuck on older Java versions or legacy systems.
GPG signing requires external key setup and configuration, and if not properly handled, it can throw exceptions like `ServiceUnavailableException`, adding operational overhead.
Specifically warns that Cygwin can cause the library to hang, requiring manual PATH adjustments, which complicates usage on Windows environments.
