Kotlin Git

An fork of the JGit project translated to Kotlin.

This project is licensed under the EDL (Eclipse Distribution License).

KGit can be imported straight into IntelliJ and built and tested from there. It can be built from the command line using Maven or Bazel. The CI builds use Maven and run on Jenkins.

• org.eclipse.jgit

  A pure Java library capable of being run standalone, with no additional support libraries. It provides classes to read and write a Git repository and operate on a working directory.

  All portions of JGit are covered by the EDL. Absolutely no GPL, LGPL or EPL contributions are accepted within this package.

• org.eclipse.jgit.ant

  Ant tasks based on JGit.

• org.eclipse.jgit.archive

  Support for exporting to various archive formats (zip etc).

• org.eclipse.jgit.http.apache

  Apache httpclient support.

• org.eclipse.jgit.http.server

  Server for the smart and dumb Git HTTP protocol.

• org.eclipse.jgit.lfs

  Support for LFS (Large File Storage).

• org.eclipse.jgit.lfs.server

  Basic LFS server support.

• org.eclipse.jgit.packaging

  Production of Eclipse features and p2 repository for JGit. See the JGit Wiki on why and how to use this module.

• org.eclipse.jgit.pgm

  Command-line interface Git commands implemented using JGit ("pgm" stands for program).

• org.eclipse.jgit.ssh.apache

  Client support for the SSH protocol based on Apache Mina sshd.

• org.eclipse.jgit.ssh.apache.agent

  Optional support for SSH agents for org.eclipse.jgit.ssh.apache.

• org.eclipse.jgit.ui

  Simple UI for displaying git log.

Warnings/Caveats

• Native symbolic links are supported, provided the file system supports them. For Windows you must use a non-administrator account and have the SeCreateSymbolicLinkPrivilege.

• Only the timestamp of the index is used by JGit if the index is dirty.

• JGit 6.0 and newer requires at least Java 11. Older versions require at least Java 1.8.

• CRLF conversion is performed depending on the core.autocrlf setting, however Git for Windows by default stores that setting during installation in the "system wide" configuration file. If Git is not installed, use the global or repository configuration for the core.autocrlf setting.

• The system wide configuration file is located relative to where C Git is installed. Make sure Git can be found via the PATH environment variable. When installing Git for Windows check the "Run Git from the Windows Command Prompt" option. There are other options like Eclipse settings that can be used for pointing out where C Git is installed. Modifying PATH is the recommended option if C Git is installed.

• We try to use the same notation of $HOME as C Git does. On Windows this is often not the same value as the user.home system property.

Features

• org.eclipse.jgit

  • Read loose and packed commits, trees, blobs, including deltafied objects.

  • Read objects from shared repositories

  • Write loose commits, trees, blobs.

  • Write blobs from local files or Java InputStreams.

  • Read blobs as Java InputStreams.

  • Copy trees to local directory, or local directory to a tree.

  • Lazily loads objects as necessary.

  • Read and write .git/config files.

  • Create a new repository.

  • Read and write refs, including walking through symrefs.

  • Read, update and write the Git index.

  • Checkout in dirty working directory if trivial.

  • Walk the history from a given set of commits looking for commits introducing changes in files under a specified path.

  • Object transport

    Fetch via ssh, git, http, Amazon S3 and bundles. Push via ssh, git, http, and Amazon S3. JGit does not yet deltify the pushed packs so they may be a lot larger than C Git packs.

  • Garbage collection

  • Merge

  • Rebase

  • And much more

• org.eclipse.jgit.pgm

  • Assorted set of command line utilities. Mostly for ad-hoc testing of jgit log, glog, fetch etc.

• org.eclipse.jgit.ant

  • Ant tasks

• org.eclipse.jgit.archive

  • Support for Zip/Tar and other formats

• org.eclipse.http

  • HTTP client and server support

Missing Features

There are some missing features:

• signing push
• shallow and partial cloning
• support for remote helpers
• support for credential helpers
• support for multiple working trees (git-worktree)
• using external diff tools
• support for HTTPS client certificates
