Conditional ANT building
Since some of the tasks differ between 1.3 and 1.4alpha/beta, I want to
perform different things for different ANT versions.
I can obtain the ANT version using the property ant.java.version, but is
there some way to say:
if ${ant.java.version} == "1.3"
echo "Using ANT 1.3"
else if ${ant.java.version} == "1.4"
do something else....
Is this possible?
Peter

How would someone check for a jvm of 1.3 being used, and those less than?
I want to enforce a fixed jdk version for development.
I use ant1.3 (currently).

To do different things for 1.4 and earlier versions? Yes, but only
because ant.version will not be defined in Ant 1.3, so you can use
target's if/unless attributes and this property.
For versions after that, <condition> and the <equals> condition should
help.

however, i don't think that's the property you really want,
since ant.java.version actually returns the version of the current
virtual machine, not the version of ant.
