Java Git
========
An implementation of the Git version control system in pure Java.
This package is licensed under the EDL (Eclipse Distribution
License).
- 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.http.server
Server for the smart and dumb Git HTTP protocol.
- org.eclipse.jgit.pgm
Command-line interface Git commands implemented using JGit
("pgm" stands for program).
- org.eclipse.jgit.test
Unit tests for org.eclipse.jgit and the same licensing rules.
Warnings/Caveats
----------------
- Symbolic links are not supported because java does not support it.
Such links could be damaged.
- Only the timestamp of the index is used by jgit check if the index
is dirty.
- Don't try the library with a JDK other than 1.6 (Java 6) unless you
are prepared to investigate problems yourself. JDK 1.5.0_11 and later
Java 5 versions *may* work. Earlier versions do not. JDK 1.4 is *not*
supported. Apple's Java 1.5.0_07 is reported to work acceptably. We
have no information about other vendors. Please report your findings
if you try.
- 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 the jgit.gitprefix system propety or 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 same value as the user.home system property.
Package 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 and Amazon S3. JGit does not yet deltify
the pushed packs so they may be a lot larger than C Git packs.
- org.eclipse.jgit.pgm/
* Assorted set of command line utilities. Mostly for ad-hoc testing of jgit
log, glog, fetch etc.
Missing Features
----------------
There are some missing features:
- gitattributes support
- Recursive merge strategy
