Hi all, I'm trying to install ant.
After using sudo, I ran this command and this is the result that I got:
$ sudo ./build.sh -Dant.install=/usr/bin
[sudo] password for developer:
Exception in thread "main" java.lang.UnsupportedClassVersionError:

Program will exit.
Ok... not what I wanted. Then, just for kicks, this is what I decided to
do:
$ ./build.sh -Dant.install=/usr install
Buildfile:
/home/developer/Downloads/apache-projects/apache-ant-1.9.0/build.xml
install:
prepare:

to /usr/lib/ant-antlr.jar due to java.io.FileNotFoundException

And that's not surprising. I do want ant to be installed in /usr/bin, but
get that funky Java error when I try.
Why is that?
How can I instally ant-1.9 on my CentOS 6.3 machine? No, it was not
pre-installed :) .
