no service on port 8001. geotrellis GeoTiffReader compilation error

[levareg]

On Ubuntu 12.04.5 LTS, from the master branch, and after applying feature/fix-sbt-launch.

When uploading a first GTFS (/#/settings/upload) using the web interface, the following error message is returned

502 Bad Gateway nginx/1.1.19

Investigating the 502 error, I found out that a request was sent to 127.0.0.1:8001, but no service is Listening on port 8001 (lsof -iTCP -P).

Manually trying to start geotrellis (/etc/init/oti-geotrellis.conf) after replacing
import geotrellis.vector.json_ by
import geotrellis.vector.io.json_
sudo ./sbt 'project opentransit' -mem 5600 run

the following GeoTiffReader error is returned, preventing geotrellis from starting

[error] /home/vbox/dev/open-transit-indicators/scala/geotrellis-transit/src/main/scala/geotrellis/transit/Main.scala:182: geotrellis.raster.io.geotiff.reader.GeoTiffReader.type does not take parameters
[error] val (jobTile, extent, crs) = GeoTiffReader(inPath).read.imageDirectories.head.toRaster

How can I get geotrellis up and running for open-transit-indicators to process GTFS?
