Setting a property using oak-run console.md

1. Download https://files.acrobat.com/a/preview/e885654b-8424-4698-b5e9-7751b647276b (or build oak-run 1.1.x version)
2. Stop all AEM instances
3. Upload the oak-run 1.1 version to the AEM server if using TarMK or MongoDB server (if using MongoMK)
4. Run this command to start the oak console

• on TarMK:

   java -jar target/oak-run.jar console --quiet /path/to/segmentstore

• For MongoMK run this:

   java -jar oak-run.jar console mongodb://localhost/aem-author

5. Run these commands to set a property on a node

setProperty(session, "/path", "propName", "propValue", false)

To build latest oak version:

   $ svn checkout http://svn.apache.org/viewvc/jackrabbit/oak/trunk/
   $ cd oak-run
   $ mvn clean install

Note: use at least maven 3.1.0
