Description Aravind 2002-08-06 10:56:06 UTC 
Hello !!!!
I just downloaded the ant 1.5 source. Did the bootstraping. Set the appropriate 
classpath and path. And when I tried to run ant on a build xml file that was 
working find in version 1.4.1 it gave me the following errors.

Kindly let me know what I should do.

D:\Projects\Scaffolding\Source_Ver1.0\Development>ant -buildfile build-
findbysql.xml -Djboss=true
Buildfile: build-findbysql.xml

BUILD FAILED

You are more than probably mixing different ant version.
On a small note, you don't have to build ant yourself, there are the binaries 
available. There are complex conditional compilation because of the huge 
number of dependencies so unless you know exactly what you are doing you will 
compile half of the classes that are delivered in an official release.
