Hi Reto,
The scala 2.7 based version in clerezza was based on the one from
sling. The 2.8 version started from scratch.
Ok I understand. So it might still be a good idea to start out with the
Scala script engine form clerezza and try to integrate the requirements
for Sling. That shouldn't be too difficult I think.
I'm not sure if the scala-incubator would allow to have thing in the
maven central repo fast enough.
Probably true. So Apache Commons would probably the best place for the
time being. When it becomes more mature and attracts some interest from
the Scala community, it might still make sense to contribute it then.

Hi,
Thanks for bringing this up again. The Scala scripting engine for Sling
evolved somewhat since it was copied over to clerezza: Sling dependencies
have been removed and factored out. AFIK the current version used in
clerezza does not fulfill some of the requirements of the Sling scripting
engine (configurability, abstraction of file system). However, since I wont
be able to contribute much in the coming weeks, I think the version of
clerezza might well serve as a starting point. I'd be happy to merge the
changes required by Sling into it later on.
However, I think the Scala incubator [1] might be a better place for the
Scala scripting engine. That way there is the chance for it making it into
the Scala distro some time in the future.

In apache clerezza we need scala in a way that:
- it can be used in an osgi container
- it exposes the scripting interfaces as per JSR 223 (javax.scripting)
At least the sling project has very similar requirements on the
foundation of their scala support, so I think it would be good to pool
this efforts and I'm wondering if this would best be pursued as an
Apache Comons project.
We have done a first implementation consisting of 3 bundles, 2 bundles
seem to be analogous to the ones available here
http://scala-tools.org/repo-releases/com/weiglewilczek/scala-lang-osgi/
(I didn't know about them originally, and the yhave the disadvantage
of not being in maven central). Our implementations has no
dependencies on other clerezza components.
The source of our implementation is here:
http://svn.apache.org/viewvc/incubator/clerezza/trunk/scala-scripting/
The current implementation is quite minimalistic and merging it with
the best from the scala support in sling could bring big improvements,
but as far as I know there's no other javax.scripting implementation
for scala 2.8.
