Ant file dependency

[Alexey Kakunin <ka...@muromoi.net>]

Hello all!

I'm quite new in ant, actuallyI'm migrating from make.
Seems it is really great tool, but I have some (probably very stupid) 
question.

For example, I have a target for compiling something by using 
idl-compiler. To do it I should use exec task to make SomeFile.h from 
SomeFile.idl. But I want to call this exec only in case the SomeFIle.idl 
was changed (has later timestamp comparing to SomeFile.h). In this case 
I have some sort of file dependency  (not a target dependency) - file 
SomeFile.h depends from SomeFile.idl.

Is it possible to implement this sort of dependency in ant?

With best Regards,
Alexey Kakunin

Hi,

check <uptodate> to set a property, and use unless in the target ;)

Hope this helps,
Nicolas
