Robert Scholte commented on MSHARED-143:
----------------------------------------
IMO escaping is the preferred solution, which has been fixed with MSHARED-228.
So I'm considering to close this as {{Won't Fix}}.

> I am trying to filter my log4j.properties file in WEB-INF. One line is
> troublesome. The resulting line should be
> log4j.appender.mine.File=$\{myProject.root}/WEB-INF/logs/mine.log
> where myProject is the value of the property project.artifactId.
> I try
> log4j.appender.mine.File=$\{$\{project.artifactId}.root}/WEB-INF/logs/mine.log
> but no substitution is done.
> After much trial and error, I use
> log4j.appender.mine.File=!#!$$\{log4j.root}/WEB-INF/logs/mine.log
> and the following in my pom.xml
> {code:xml}
> <properties>
> <log4j.root>{$project.artifactId}.root}</log4j.root>
> </properties>
> ...
> <build>
> <plugins>
