Re: Building Events

Hi Adam,


Try providing <classpath refid="build.classpath"/> to not only the taskdef 
definition of events, but also to the <events> element itself.  so...

<events srcdir="${build.event_source.dir}" destdir="${build.classes.dir}" 
descriptor="${src.dir}/${src.package.path}${subdir}">
     <classpath refid="build.classpath"/>
</events>

BTW, one little nit.  I never write a path with a trailing slash 
("/").  This way, if I ever need to add some more stuff to that path, I 
know that I need to explicitly add a "/" between the two paths being 
concatenated.  I suppose if you always add a trailing slash to your paths 
and treat it consistently that way, then that would be ok as 
well.  However, in the above, there is an explicit "/" between ${src.dir} 
and ${src.package.path}, but not between ${src.package.path} and 
${subdir}.  This is inconsistent and can lead to hard to identify 
errors.  Also, there may be times where a trailing slash will change the 
behavior of a task given a particular path.

later,

Jake
