mvn sling:deploy -Dobr=?

[Sandro Boehme]

Hello,

I would like to deploy my bundle to the local Sling instance and get my 
dependency to JSTL resolved automatically (to be able to use the JSTL 
expression language) using Maven. But I could not find out what obr url 
is configured in a default sling installation. Can somebody tell me 
which one to use?

Judging from Google search results people generally seem to prefer 
sling:install over sling:deploy and useful features like "mountByFS" are 
included in sling:install but not in sling:deploy. Is there any 
advantage of installing over deploying I'm not aware of?

Best,

Sandro
