I do not like personally 'find' model to be present in ANT. I like a
lot, the way processing of my build inputs works currently in ANT - which
is distinct from traditional 'make' and 'find'-based models.
I cannot see when:
<task1 ... ${find.file} ${find.dir} ... />
<task2 ... ${find.file} ${find.dir} ... />
would be of use? Everywhere the task can take a list of files, it itself
implements include/exclude model, like javac/delete etc. With find we
would have two ways of doing the same thing, which I feel would break
the rule of making things simple. For example if I have to compile
all my java source files in one directory and then copy them to the
distribution src directory, in current ANT, with 'no-find-philosophy'
I do:
1. compile all java files from _src.dir_
2. copy all java files from _src.dir_ to _dist.dir_
with 'find' it usually looks like:
1. find all the java files from _src.dir_
2. compile all what's in ${find.file} ${find.dir}
3. copy all what's in ${find.file} ${find.dir} to _dist.dir_
Do not tell me that you do not like the beauty, simplicity and
the very explicit way of the first (current ANT) model. Everywhere ANT
lacks the excludes/includes model (like in current exec) it needs
simple to be extended. Apart from that, in Unix:
find <dir> -name <regexp> -exec <task>
<task> is performed sequentially one call per found item. In most cases
(like in the one with compiling and copying) you do not want the task
to be performed n times, once per each found item, you want it to be
performed once with the list of items (which I suppose the propose
find task would differ from the real
find <dir> -name <regexp> -exec <task> ).
Do not get me wrong, I love 'find', and it would be not possible to
have 'make' without it, but I am very happy not to have find in ANT,
and I do not feel the need for it here either. When do you need find
task to be used? and with what tasks?
