Subject Building from a list...
Date Tue, 25 Apr 2006 16:13:19 GMT
hello,

i'm having a bit of a brain-fart coming up with a solution to this
situation.  we have about 130 JAR files that we are building for a
particular project.  most of these JARs are dependent on each other so
they require a specific build order.  i was hoping to create a list of
the projects that compose each JAR and feed this list to ANT to build
one at a time.  i know the Ant-Contrib project has a <foreach> tag
that allows for iteration, but i'm a bit stumped on how to build
everything from a properties file.  is this possible?  or is there a
better way to approach this?

we're using VSS as source control and have several projects that are
composed of several (130+) products/JARs in VSS.  so i'd like to make
a list of Project.Product that i can iterate through and
build/JAR/deploy in order.
so in VSS we may have Project1 that contains ProductA, ProductB &
ProductC and Project2 that contains ProductD & ProductE and Project3
that contains ProductF, ProductG & ProductH.  the build order may end
up being:
ProductB, ProductG, ProductA, ProductC, ProductD, ProductF, ProductE...
so my initial idea was to create a master list that contains these
products in their proper build order:
Project1.ProductB
Project3.ProductG
Project1.ProductA
Project1.ProductC
Project2.ProductD
Project3.ProductF
Project2.ProductE

our ANT build file is currently set up to build products individually.
 so typically we'd pass in the ProjectName, ProductName, Branch,
DeliverableType and DeploymentDest to build one product/JAR/etc.  to
build all applications (build world) we have to either type this in
manually 130+ times or we use a .bat file that makes 130+ calls.  the
problem with the .bat file is that if product 15 fails a bunch of
builds that follow will fail due to dependency.  there is no good way
to stop the build process on error.  so i was hoping ANT would be able
to come to the rescue. :)
hopefully this is enough background to either come up with a solution
or generate some discussion that will lead to a solution.
thanks for any help you can offer.
