Subject [jira] (DOXIASITETOOLS-79) APT document with verbatim section including C #include causes NPE
Date Mon, 21 Jan 2013 07:19:14 GMT

     [ https://jira.codehaus.org/browse/DOXIASITETOOLS-79?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Lukas Theussl closed DOXIASITETOOLS-79.
---------------------------------------

    Resolution: Not A Bug
      Assignee: Lukas Theussl

This only happens when you use filtering (*.vm). In this case the source file is first piped
through velocity which doesn't know anything about apt syntax, so you have to escape the velocity
special characters.

> A simple apt.vm document including a C program fragment in a verbatim section causes
"mvn site" to fail with a NPE.  The failure can be worked around by escaping the # as backslash-#
but the requirement to do this is not documented, nor AFAICS is the feature of supporting
#include in verbatim sections.
