These instructions explain how to get the source code for Roller from Roller's Subversion repository, import it in to Eclipse and run it via an Eclipse launcher that starts Jetty and Derby.

h1. Prerequisites

These instructions assume you have these things already installed on your computer:
* Sun Java SE 1.6
* Subclipse Subversion client for Eclipse
* M2Eclipse Maven client for Eclipse

h1. Checkout code from Subversion

Use the *File->Import* menu in Eclipse to start the Import, then choose the *Checkout Projects from SVN* option. _(If you are wondering why we don't suggest using the "Check out Maven projects from SCM" option: it does not work. See this issue for_ _[MNGECLIPSE-2596|https://issues.sonatype.org/browse/MNGECLIPSE-2596]_ _details.)_

h1. Building and running Roller

To build all of the Roller code, right-click on the roller-project project, choose *Run As* and then choose "*Maven install*." If you change anything in a project, you'll have run Maven Install on the project before you attempt Roller.

The Eclipse Maven plugin can also run Roller for you and will start both the Jetty web service and the Derby database for Roller. To run Roller, use Eclipse's *Run->Run Configurations  *to create a launcher for Roller. Create a new launcher under Maven Build, set these fields:

* Base directory: {preformatted} *${workplace_loc:/roller-weblogger-webapp}{preformatted}*
* Goals: *jetty:run*

Then you can use the *Run* button to start Roller.

Navigate to [http://localhost:8080/roller] and you'll find Roller up and running.
