JavaSVN^TM - the only pure Java^TM Subversion client library in the World.

JavaSVN^TM is a powerful pure Java Subversion (SVN) client library. This means that users of the library, i.e. java applications do not have to include SVN native binaries or javahl bindings to work with a Subversion repository.

The library represents two main concepts for developers who use a Subversion repository in their projects:

Low-level API - the package org.tmatesoft.svn.core.io - a solution for those developers who doesn't need to work with the native Subversion high-level format known as 'Working Copy' - that is when all local files are stored in a filesystem and all version controll metadata is concentrated in .svn directories. For instance, those developers who would like to customize managing versioned files - like storing and managing versioned data as well as all metadata within a data base - will certainly find this package pretty suitable for their purposes.

High-level API - the package org.tmatesoft.svn.core.wc - this is a set of classes and interfaces designed to provide developers means for working particularly with the native Subversion client's format - 'Working Copy'. All the commands supported by the SVN command line client can be also easily performed by using this high-level API. Obviously in those cases when an operation needs an access to a repository this high-level API uses the low-level one.

Features

JavaSVN supports the following repository access protocols:

svn://, svn+ssh://
http://, https://
file:/// (Since 1.1.0 and for FSFS-type repositories only)

Since 1.0.2

Support for error codes similar to error codes of the native SVN.

Since 1.1.0

JavaSVN can create empty local FSFS-type (Subversion compatible) repositories.

JavaSVN can replicate revisions from one repository to another one. This allows to clone repositories. Also repository replicator supports incremental mode: if you've copied a repository, then created some new revisions in it and would like to have them in your repository clone too, you do not need to copy the whole original repository again - you simply copy those missing revisions to the clone and it's up to date with the original one again!

svn+xxx:// URL schemes (not only svn+ssh). JavaSVN API gives a user an ability to define tunnel providers which are responsible for matching subprotocol names (xxx) to tunnel command lines.
