Rodar JPA em IntelliJ

Meus caros, boa tarde!

Tenho um projeto maven básico inicial de JPA com hibernate, onde tenho a seguinte estrutura:
Pom.xml:

<dependency>
        <groupId>org.apache.maven</groupId>
        <artifactId>maven-plugin-api</artifactId>
        <version>2.0</version>
    </dependency>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>3.8.1</version>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
        <version>5.2.12.Final</version>
    </dependency>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.38</version>
    </dependency>
</dependencies>


<build>
    <finalName>introducao-jpa</finalName>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.0</version>
            <configuration>
                <target>1.8</target>
                <source>1.8</source>
            </configuration>
        </plugin>
    </plugins>
</build>

persistence.xml

<properties>
        <!-- Driver JDBC para conexão com o MySQL -->
        <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>

        <!-- Propriedades para conexão com o banco de dados -->
        <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/dbIntroJPA?createDatabaseIfNotExist=true"/>
        <property name="javax.persistence.jdbc.user" value="root"/>
        <property name="javax.persistence.jdbc.password" value="123456"/>

        <!-- Configurações do Hibernate -->
        <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/>

        <!-- Atualiza o banco de dados, criando as tabelas caso necessário -->
        <property name="hibernate.hbm2ddl.auto" value="update"/>
    </properties>
</persistence-unit>

A minha dúvida é a seguinte: utilizando essas dependências, é necessário ter o mysql instalado localmente ou fazer alguma configuração extra na parte de databases no IntelliJ?

Estou tendo o seguinte stacktrace:

Poderiam me dar uma luz?
Desde já, agradeço!
