Subject Re: ZooKeeper Roadmap - 3.1.0 and beyond.
Date Thu, 06 Nov 2008 03:00:44 GMT
Hi Hiram,
I actually am just a user of zookeeper, I am not a "member" as of yet.  I am
also a user of maven and ant and have been using both for many years.

So while I would say it is never a bad decision to move to maven, it isn't
always a needed decision.

A standard build structure makes sense if you were building zookeeper
yourself, but I don't beleive you would be doing that.  So that leaves the
creation and building of your own projects like an ear, war, JBI, etc.  The
problem with zookeeper is that there is no required project structure.
There is no zar that is to say.

I personally have a mavenized war project that I am using zookeeper in and I
also have a hand rolled CL java program that uses it and is build with ant.
For both of these I just needed to copy one jar into my lib.
As far as dependency management, since zookeeper is so simple the only
requirement is log4j, not really needing any complex dependency tools there.

As far as modularity, again I see zookeeper being part of larger modules, so
I don't know if we can draw a common modular zookeeper application
structure.

Maven is a great tool and can help alot, but I personally don't see it as
synonymous with modern java development.
