IntelliJ IDEA says Maven class not found

I am using IntelliJ IDEA. I have one sample Java code which requires MySQL driver class using class.forName(); to get database connection. It is a standalone Java application. When I run the main method of that class, I get ClassNotFoundException. But, I have that sample code in a Maven project in which MySQL jar is configured. What am I missing? Eclipse does the job.

There are different scope for maven import

<scope>provided</scope>

Check. Scope should not be provided.

Thank you for your kind answers. I found that the maven dependency is scoped to 'provided'. So, Intellij IDEA was not looking out for that jar because of the scope. When I changed the scope to compile(no scope tag), it is working fine. But without any change the configuration worked fine in Eclipse.

Add these lines to Manven dependencies:

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.34</version>
</dependency>

And checklist:
- %M2_HOME%
- .m2 directory existing.
- Check internet connection.
- Check enabling Maven plugin inside IntelliJ IDEA.
- Add MySQL ConnectorJ jar file to lib inside application server.
