Subject Re: Resource filtering difficulties.
Date Mon, 11 Jan 2010 13:41:45 GMT
Your solution actually gave me a NullPointerException (in plexus-filtering),
because ${*} is replaced by "the value of property *" in the pom.

So you have to use
<delimiter>$${*}</delimiter> (It took me a while to figure out that
the ${ } is escaped by doubling the dollar sign :-))

Here's the jira issue I filed for improving the docs:
http://jira.codehaus.org/browse/MRESOURCES-115

Regards,
Karel
