It looks like the problem is that you are getting incompatible versions of jackson-core and jackson-databind – jackson-core 2.0.5 is being pulled in, but I believe at least 2.1.0 is required.
The first line of the exception tells you that it can’t find the method JsonParser.getValueAsString(), looking at the API docs for 2.0.5, that method indeed does not exist. It looks like it was added in 2.1.0.
So, you’ll need to fix the dependencies – most likely by excluding 2.0.5 and including 2.1.0.
