json dependency added in pom.xml get error

Question

I am working with Sparse Matrix in my project. To build a Sparse Matrix I am using Universal Java Matrix Package. I add all the dependency in my pom.xml file.My pom.xml file is like that.

 <?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <artifactId>ujmp-json</artifactId>
        <version>0.3.0</version>
    </dependency>
</dependencies>

I added this dependency on my own. All the dependency in added from ujmp.org website from there documentation. After added all the dependency one error is still there Error:(30, 16) java: package org.json does not exist.Error:(75, 40) java: cannot find symbol symbol: class JSONTokener location: class org.ujmp.core.util.JsonUtil. Error:(72, 38) java: cannot find symbol symbol: class JSONTokener location: class org.ujmp.core.util.JsonUtil

So I think added json dependency in my pom.xml file should remove the error.

 <dependency>
        <groupId>org.ujmp</groupId>
        <artifactId>ujmp-json</artifactId>
        <version>0.3.0</version>
    </dependency>

But error not removed and the version 0.3.0 is not recognized. It show in a red sign. So what should I do? I am using Intellij Idea. There is no dependency added for json in the UJMP official website. Please give me a suggestion.

`ujmp-core` core is not declared as a dependency, it is declared as if your project itself was `ujmp-core` . — Arnaud, Jul 12 '18 at 07:55

remove:

<groupId>org.ujmp</groupId>
<artifactId>ujmp-core</artifactId>
<version>0.3.0</version>

add in dependencies:

<dependency>
    <groupId>org.ujmp</groupId>
    <artifactId>ujmp-core</artifactId>
    <version>0.3.0</version>
</dependency>
