都采用subversion
进行版本控制，可以根据URL通过浏览器直接查看，也可以用svn客户端checkout下来，仔细研究源码还是不错呀。

Source Control Repositories

Starting in March, 2006 Hibernate
source is maintained in a Subversion repository hosted by the JBoss Labs
project. For anonymous access, the root repository URL is http://anonsvn.jboss.org/repos/hibernate/
. For
developer access, the root repository URL is https://svn.jboss.org/repos/hibernate/
.

Also, the repository layout is
expected to change to better align with the subproject structure.
Currently, the layout essentially follows that found in the older CVS
modules, with trunk, branches, and tags all at the root level of the
repository. Thus to checkout the latest source for the Hibernate3
module, type

svn co

http://anonsvn.jboss.org/repos/hibernate/trunk/Hibernate3

To checkout Hibernate Annotations and Hibernate
EntityManager, type

svn co

http://anonsvn.jboss.org/repos/hibernate/trunk/HibernateExt

or (for branch 3.2)

svn co

http://anonsvn.jboss.org/repos/hibernate/branches/Branch_3_2/HibernateExt

Then you'll find metadata

which contains Hibernate Annotations, ejb
which contains
Hibernate EntityManager and ejb-api
which contains the
javax.persistence APIs of EJB3.

Note that some of the modules present in CVS were
dropped after import into Subversion; namely Hibernate and Hibernate2
modules. If you need access to these source trees, they are still
accessible from the SourceForge CVS repository. For anonymous access,
use pserver:anonymous@cvs.sourceforge.net:/cvsroot/hibernate as the
CVSROOT.

NHibernate uses Subversion hosted on Sourceforge. The
repository URL is https://svn.sourceforge.net/svnroot/nhibernate. Using
this URL directly will cause all branches and tags of the project to be
checked out, transferring a large volume of data. To check out only the
trunk (main development line), use
https://svn.sourceforge.net/svnroot/nhibernate/trunk as the repository
URL.

The repositories are also browsable online via ViewCVS
and Fisheye.
