Robert Munteanu commented on SLING-8167:
----------------------------------------
I personally would like for {{sling.home}} to be automagically available as a
variable so I can use it without any preparation. However, I would be OK with
Karl's suggestion of catching these kinds of problems as logging a warning
message (or an error if we're sure nothing good can come out of it).
> Using sling.home as a variable leads to runtime errors

> Key: SLING-8167
> URL: https://issues.apache.org/jira/browse/SLING-8167
> Project: Sling
> Issue Type: Bug
> Components: Feature Model
> Affects Versions: slingfeature-maven-plugin 0.8.0
> Reporter: Robert Munteanu
> Priority: Major
>
> I tried using ${sling.home} as a variable but replacement did not work and
> ended up failing at runtime when the property was used to try and create a
> directory, e.g. - failed creating directory "/${sling.home}/foo".
> I was able to work around by declaring a ${sling.home}: null variable but I
> wonder whether we can have better handling of such scenarios.
