Hello.
I have a target called 'bind' in my build which uses xjc (JAXB .xsd -> .java
compiler) to compile XML schema files into Java sources. Currently, 'bind'
runs on every run of any target that depends on it - ant doesn't know when
the target is up to date. I want it to run only when the source xsd files
are newer than the generated .java files.
At first, the dependset tag looked promising, but I now realise that adding
a dependset will have ant run the target when the dependset indicates it
should *in addition* to the other times it's running (which is always). What
I want is a dependset that has its enclosing target run *only* when it
indicates.
Is this possible?
Cheers,
Eliot Stock
