You've done something (that's for you to figure out) that causes your
project to ship a jackson-databind version that's older than the one
expected by Gatling 2.2.2.

 I have a simple CSV I'm trying to use in the user-files/data directory, in
 the format of:
 loginEmail,loginPassword
 "test+s...@example.com","password"
 "test+s...@example.com","password2"
 ... (etc)
 Trying to create the feeder gives an error:
 Code:
 package example
 import io.gatling.core.Predef._
 import io.gatling.http.Predef._
 import io.gatling.jdbc.Predef._
 import io.gatling.http.HeaderNames._
 import io.gatling.http.check.HttpCheck
 import scala.concurrent.duration._
 import util.Random
 import io.gatling.jsonpath.JsonPath
 object Login {
     val loginFeeder = csv("customer_accounts.csv")
 ...
 Removing / commenting the csv line (and anything referencing it) will
 prevent the error from occurring, though I then have to hard code the
 values it's meant to replace for the script to actually work. If I put the
 file somewhere else or otherwise make the path to the file wrong, I get a
 corresponding error about the CSV file not being found, so it at least gets
 as far as trying to read the file. Nothing in the CSV file is outside the
 range of [0-9a-zA-Z] except for the '@' in the email field, and the commas
 and quotation marks formatting the CSV file itself.
 This is the error I get:
 Exception in thread "main" java.lang.NoSuchMethodError:
 com.fasterxml.jackson.databind.ObjectMapper.readerFor(Ljava/lang/Class;)
