rest assured imports are not resolved

Question

I have included rest assured jars in my POM as below.

    <dependency>
    <groupId>io.rest-assured</groupId>
    <artifactId>rest-assured</artifactId>
    <version>3.0.0</version>
    </dependency>

But still the import statements are showing "The import io cannot be resolved". If i download the rest assured jars and add them manually as external jars the error disappears.

import static io.restassured.RestAssured.*;
import static org.hamcrest.Matchers.*;

I tried removing the

<scope>test</test> 

tag also as suggested in some sites. This doesn't solve the issue.

import static io.restassured.RestAssured.*;
import static org.hamcrest.Matchers.*;

import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

import io.restassured.RestAssured;

public class OpenURL {

    @BeforeClass
    public void initPath() {

        RestAssured.baseURI = "http://localhost:9876";
    }

    /*******************************************************
     * Send a GET request to /api/f1/2016/drivers.json
     * and check that the answer has HTTP status code 200 
     ******************************************************/

    @Test
    public void checkResponseCodeForCorrectRequest() {

        given().
        when().
            get("/api/f1/2016/drivers.json").
        then().
            assertThat().
            statusCode(200);
    }
}

My complete POM is here. I am not finding any issues here.

I doubt the "dependencyManagement" tag, can you try with the below

  <version>0.0.1-SNAPSHOT</version>
          <dependencies>
            <dependency>
                <groupId>io.rest-assured</groupId>
                <artifactId>rest-assured</artifactId>
                <version>3.0.0</version>
            </dependency>
            <!-- https://mvnrepository.com/artifact/org.testng/testng -->
            <dependency>
                <groupId>org.testng</groupId>
                <artifactId>testng</artifactId>
                <version>6.9.10</version>
            </dependency>
            <dependency>
                <groupId>org.codehaus.groovy</groupId>
                <artifactId>groovy-all</artifactId>
                <version>2.4.5</version>
            </dependency>
        </dependencies>
