java - How to resolve error - package com.squareup.okhttp3 doesn't exist? -

i trying convert json java object use of gson in maven, following youtube video guidance - https://www.youtube.com/watch?v=vqgghm9pwe0 , theres error occurs when in main class error - package com.squareup.okhttp3 doesn't exist. code below:

java

package com.codebeasty.json; import com.squareup.okhttp3.okhttpclient;  public class main {      private static okhttpclient client = new okhttpclient();     public static void main (string [] args)     {     }  } 

i put in dependency in pom.xml:

  <dependencies> <dependency>  <groupid>com.squareup.okhttp3</groupid>  <artifactid>okhttp</artifactid>  <version>3.4.2</version> </dependency>  <dependency>  <groupid>com.google.code.gson</groupid>  <artifactid>gson</artifactid>  <version>2.8.0</version> </dependency>  </dependencies> 

i dont understand why doesn't recognize com.squareup. there may need download? have downloaded jar website - http://square.github.io/okhttp/ , tried building project dependencies. please :(

mvn install:install-file -dfile=path/to/okhttp-3.4.2.jar -dgroupid=com.squareup.okhttp3 -dartifactid=okhttp -dversion=3.4.2 -dpackaging=jar
