Subject Can't get ant to install...
Date Tue, 02 Apr 2013 17:37:58 GMT
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:

Could not find the main class: org.apache.tools.ant.launch.Launcher.
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:

check_for_optional_packages:

build:

BUILD FAILED

to /usr/lib/ant-antlr.jar due to java.io.FileNotFoundException
/usr/lib/ant-antlr.jar (Permission denied)

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 :) .
