NullPointerException when running ivy report on Linux

[Nyc Ivy <ny...@yahoo.com>]

Hi,

Can anyone assist with the error below?
It only occurs on Linux. Windows is fine.

My ant task has is as follows:

<target name="_ivy-report" depends="init-ivy">
  <ivy:report todir="${build.dir}/reports/ivy"/>
</target>

TIA
_ivy-report:
    [mkdir] Created dir: /home/qabuild/dev/build/reports/ivy
Overriding previous definition of property "ivy.version"
