Packaging/release artifacts

The release artifact contains the following jar file at the toplevel:

zookeeper-.jar - legacy jar file which contains all classes and source files. Prior to version 3.3.0 this was the only jar file available. It has the benefit of having the source included (for debugging purposes) however is also larger as a result

The release artifact contains the following jar files in “dist-maven” directory:

zookeeper-.jar - bin (binary) jar - contains only class (.class) files zookeeper--sources.jar - contains only src (.java) files zookeeper--javadoc.jar - contains only javadoc files

These bin/src/javadoc jars were added specifically to support Maven/Ivy which have the ability to pull these down automatically as part of your build process. The content of the legacy jar and the bin+sources jar are the same.

As of version 3.3.0 bin/sources/javadoc jars contained in dist-maven directory are deployed to the Apache Maven repository after the release has been accepted by Apache: http://people.apache.org/repo/m2-ibiblio-rsync-repository/
