No, they are not. If you visit the Apache Ant Web site's download page, you can download Ant 1.8.2 from any of the mirrors.

I think your problem is that you have not set the JAVA_HOME variable to point at a Java JDK. See the ANT installation instructions:

http://ant.apache.org/manual/install.html#advanced

Rather confusingly Java comes in two flavours, JRE and the JDK. It's the latter that contains tools like javac for compiling java code.
