Instalação do Ivy - ivy.jar em / usr / share / ant / lib não está funcionando

Estou tentando instalar o Apache Ivy e baixei o binário. Seguindo a pergunta aqui: Como instalar o ant & ivy? e instruções aqui: http://ant.apache.org/ivy/history/2.3.0/install.html Mudei o binário do diretório de download como tal:

sudo cp ivy-2.3.0.jar /usr/share/ant/lib/ivy.jar

No entanto, quando eu corro formiga do exemplo do hello-ivy, ainda recebo:

apache-ivy-2.3.0/src/example/hello-ivy/build.xml:38: Problem: failed to create task or type antlib:org.apache.ivy.ant:retrieve
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.
No types or tasks have been defined in this namespace yet

Eu também tentei colocá-lo em $ HOME / .ant / lib. Eu também tentei executar da seguinte forma:

ant-lib / usr / share / form / lib

Estou executando o CentOS6.4 com Ant 1.7.1.

Ele ESTÁ aparecendo no meu classpath. De antdiagnósticos:

Tudo sem sucesso. Alguém tem alguma ideia?

Esse problema parece estar relacionado à versão do ant (1.7.1) ou ao fato de que eu estava usando a versão RPM do CentOS / RedHat. De acordo com a lista de discussão, http://www.mail-archive.com/ivy-user@ant.apache.org/msg05766.html , há um problema conhecido na versão do RPM. Eu instalei a versão mais recente do ant (1.9) na minha máquina e tudo funcionou bem.
