Docbook to PDF via FOP question which related to ANT

[Lars Vogel <lars.vogel@gmail.com>]

Hi,

not sure if this is the right distribution list.

I'm running an Apache Ant build to create PDF files from Docbook
input. This includes the translation to fop and afterwards running the
<fop> Ant task. If I assigned twice the the same ID I get Java
exceptions. See below for an example.

All this is good and well, only that the Ant build finishes successful.

Is their a way to tell Apache Ant to fail the build if such an exception occurs?

Best regards, Lars
