[jira] Commented: (MRESOURCES-29) An escape mechanism for property interpolation is missing.

["Dan Hardiker (JIRA)" <ji...@codehaus.org>]

Dan Hardiker commented on MRESOURCES-29:
----------------------------------------

I have tried the following, none of which work:

* *$\{dollarSign}\{id}* where dollarSign = $
* *$\{dollarSign}@start@id@end@* where dollarSIgn = $, start = \{, end = }
* *@start@id@end@* where start = ${, end = }

All yeild in the same result - the artifact's full ID being spat out. What I am looking for is a simple solution where I can put down *$$\{id}* or *\$\{id}* and have that come out the other side as literally *$\{id}*.

Any _working_ work-arounds are appreciated!

> It would be great, if there was a mechanism that let's you escape a property so that it is not replaced by the filtering machism. E.g. in a log4j.xml configuration file you might want to preserve ${user.home}, but replace some other property like ${log.dir}. Currently there is no convenient way to achieve that.
> Alternatively to escaping, it would be helpful, if one could choose the token format. So, if one could say, only honor @token@ and not ${token} (or the other way around) one could easily work around the escape problem.
> Workaround for the problem mentioned above:
> replace the ${user.home} in log4j.xml with @start@user.home@end@ and define     start=${    and end=$}   in the property file
