Err when importing a dependency

Question

I am coming from a ruby programming background and I have started learning java. I absolutely fell in love with it. Right now I am trying to run the sample aws iot java sdk project but I keep getting this err.

import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;

The import com.fasterxml.jackson.databind.DeserializationFeature cannot be resolved

When I looked inside the maven dependency folder and navigated to com.fasterxml.jackson.databind I did not find any class with DeserializationFeature as well as ObjectMapper

Any idea?

@passion, could it be? I will try to update it. btw it was installed by default. — Sushant Bajracharya, Sep 20 '16 at 05:23
@jens I assumed that it was not necessary since eclipse was adding it by default. My bad. Thanks for ur help though — Sushant Bajracharya, Sep 20 '16 at 05:35
eclipse do nothing by Default. Maybe that is a dependency of one of your other dependency. — Jens, Sep 20 '16 at 05:36

Can you confirm the version of the jar .... its part of jackson.databind.jar ... you might need the correct version

You need to add dependency for jackson-databind

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>2.8.0</version>
    </dependency>

it should be in jackson-databind-2.8.0.jar – ravthiru Sep 20 '16 at 05:32
ya it is . I was assuming that it would be on its separate file but it turns out that it is a method inside the databind class. thanks again mate – Sushant Bajracharya Sep 20 '16 at 05:34
