Unable to properly install binary edition of Apache Ant

I'm following this tutorial to install the binary edition of Apache Ant.

Unfortunately, when I get to the "optional" step 5, I'm unable to get some resources. That is, an error occurs while processing the Maven artifact tasks.

When I try to navigate to the servers, it appears that they are either down, or non-existent. Anyone else encounter this problem?

And I just found this piece of information regarding the HTTP 403 response code,

This response is returned by the Apache web server when directory listings have been disabled.

So, would enabling directory listings 开发者_开发百科fix this? And if so, how do I go about enabling that?

It seems that Ant is trying to download some JARs from a Maven repository on the Internet, in this case on JBoss' site. They changed the location of their repository some time ago.

Here's how to change the URL:

1. Go to your ant installation folder.

2. Open fetch.xml in your favorite text editor.

3. Search for http://repository.jboss.org/maven2 and replace it with https://repository.jboss.org/nexus/content/repositories/thirdparty-releases/

Run the optional command again:

ant -f fetch.xml -Ddest=system
