Ivy installation seems broke with JPackage ant

[Brian Feeny <bf...@me.com>]

I am having an issue where it looks like Ivy will not work with the RPM version of Ant installed.

I searched the archives, and found the same problem going back to 2008.  I would hate to switch off of the RPM version of Ant so I am hoping
someone here can help me with this issue.


I am using CentOS 6.3 with ant-1.7.1-13.el6.x86_64:

[root@hadoop01 hello-ivy]# yum info ant-1.7.1-13.el6.x86_64

Trying to build Ivy fails:

[root@hadoop01 hello-ivy]# ant
Buildfile: build.xml

resolve:

BUILD FAILED

This appears to be an antlib declaration.

It seems to be related to the /etc/ant.conf file installed by the RPM version of ANT:


[root@hadoop01 hello-ivy]# cat /etc/ant.conf 
# ant.conf (Ant 1.7.x)
# JPackage Project <http://www.jpackage.org/>

# Validate --noconfig setting in case being invoked
# from pre Ant 1.6.x environment
if [ -z "$no_config" ] ; then
  no_config=true
fi

# Setup ant configuration
if $no_config ; then
  # Disable RPM layout
  rpm_mode=false
else
  # Use RPM layout
  rpm_mode=true

  # ANT_HOME for rpm layout
  ANT_HOME=/usr/share/ant
fi

if I set --noconfig, everything works fine:

[root@hadoop01 hello-ivy]# ant --noconfig 
Buildfile: build.xml

Does anyone have any ideas? The closest info I could find which I did not totally understand was here:
