Unless I missed it somewhere, no one has mentioned the extra bloat in
your source distributions (if you include the binary dependencies).
James,
you need the binary dependencies anyway to build the project, so what is
your point? You download the source distribution with libs included or
you download the source distribution without libs and ant does the lib
download afterwards. The sum of required network traffic is the same.
That's true for the developer. But I was also considering ASF hardware
and bandwidth. Again, that's a drop in the bucket if only MyFaces were
doing it. But you are not. I have had this same conversation (beating
the same dead horse) with developers on other projects, both here, sf.net,
and many, MANY closed source projects.
Oliver, I'm having a hard time understanding your point.
I can see how one wouldn't care about disk space and bandwidth,
because you (nor I) currently pay for neither. But how much more
"simple" can building a project be then calling "ant". That's all you
should have to do to build the project.
Please explain to me what makes it "not simple" if the ant script
automatically goes out and gets the dependencies the first time you
run the script (and never has to do it again unless a dependency is
added or changed) ??
It get's "not simple" as soon as the automatic download fails for
whatever reason. I had problems in the past with maven-based builds
because the attempt to download required libs ended up in corrupt jars
in the local repository because ibiblio was not available and all the
downloaded jars actually were http 404/500 error pages. The result is a
long list of strange error messages talking about corrupt zip files and
stuff like that. What you plan to do with ant is just another way to the
same potential problem.
I'm not sure why you keep talking about corrupt binaries. This is not
even a valid case. At least not with any of the last 5 versions of Ant
that I have used.
Let me explain:

you continue to make this assumption that someone is smart enough tobe
able to download and configure both SVN and Ant, and checkout theproject,
yet so dumb that they would "throw it in the trash" on the firsterror.
That's not making a lot of sense to me. That's why we have a userslist,
and forums, and books, and many articles and blogs about the same.--James
