variable of the target passed in

[Danny Zapata <dz...@bea.com>]

Is there a variable which references the command-line target specified by
the user?

i.e. if the user types ant build, is there variable that represents 'build'
from within the build.xml file?

This would be very useful for passing into dependent projects.

Good question. I'll try to give a good answer.

My point was that if one of the modules generates what effectively might be
thought of as a library, then when a stable version has been created, copy
it across to the other modules that depend upon it and us it there. We do
this internally here, we have a standard corporate Java library, and when we
hit a period of stability, we declare a new version and make it available to
our developers. The periodic release of stable versions allows other
developers to use it while still allowing active development on the library
itself. The library is built with ant and has unit tests, so knowing if we
have a stable build is fairly easy).

Concerning naming conventions, I am actually in transition. I used to just
label the library with it's name and no version or datestamp info. So our
library was called "landsend.jar". I am now leaning towards appending
version numbers, in the open source style, to the library name, which would
give me something of the order of "landsend-1.2.3.jar" My reason for
switching (to use the Apple term) is that anymore, ant removes the worry of
complicated CLASSPATHs anymore. For many Java tools anymore, just drop a JAR
file into a lib directory and "hey presto" it's available.
