Include tag - filetype not known warning

Hi there,

I'm adding sql files to a databaseChangeLog in the following manner..

<include file="this_file.sql" relativeToChangelogFile="true" />

If the file added is in uppercase (named '.SQL' rather than '.sql'), then a warning is given and the file is ignored.
Is there any way to add an onFail tag or something similar, so that it fails, rather than just a giving a warning?

Thanks in advance,
Rhod
