I'm not sure how you can perform the dependency checking without
actually comparing file modification dates. However, the <uptodate/>
task makes this a lot easier than the file::up-to-date function, when
multiple files are involved. Were you aware of it?

Subject: [NAnt-users] Checking Build Dependencies for External
Applications
Hello All,
I've been working with NAnt for about a three months now and along the
way I've learned a lot, but I've yet to figure out the best way to check
build dependencies for external applications. In a perfect world, I
would be able to develop an application in a single language, but I work
with a project that needs to compile source code from languages such as
C++ and Java. To accomplish this, I use the exec task with build tools
such as make, javac, jar, g++, libtool etc... However, the build is far
from efficient, because I have situations where targets have multiple
source file dependencies. The solution that I came up with was to use:
unless="${file::up-to-date(src,target)}"
in the target element to determine if a file needs to be rebuilt. This
works pretty well when there is a one to one dependency, but does not
help much in situations where I have targets that have multiple
dependencies. For example, I build a class file from A.java that
depends on B.java, C.java and D.java. In this case I need to check if
all the dependencies are up-to-date. I was considering writing a
function that takes a list of dependency files and then check for
modifications against the target. I was also thinking of just writing a
target that checks all of the dependencies and then sets a property if a
compile needs to happen. Anyway, before I made a decision I thought I
would ask the community for suggestions. Cheers.
