Logback configuration file not loaded

Question

I'm working on a maven project and I use slf4j to perform logging but my problem is my logback.xml configuration is not loaded and it won't take effect on my project. My logback.xml is placed in src/main/resources folder

Dependencies:

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>${logback.version}</version>
</dependency>
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-core</artifactId>
    <version>${logback.version}</version>
    </dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>jcl-over-slf4j</artifactId>
    <version>${jcloverslf4j.version}</version>
</dependency>

logback.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE XML>
<configuration>

    <!-- Appenders -->
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <!-- encoders are assigned the type ch.qos.logback.classic.encoder.PatternLayoutEncoder 
            by default -->
        <encoder>
            <pattern>[%d{dd-MM-yyyy HH:mm:ss.SSS}] [%-5level] [%logger{36}.%M\(%line\)] - %msg %n</pattern>
        </encoder>
    </appender>

    <!-- Application logger -->
    <logger name="com.example">
        <level value="info" />
    </logger>


    <!-- Root Logger -->
    <root level="DEBUG">
        <appender-ref ref="STDOUT" />
    </root>

</configuration>

Main class:

public class Main {

    private static Logger logger = LoggerFactory.getLogger(Main.class);

    public static void main(String[] args) {

        logger.trace("hi");
        logger.debug("hi");
        logger.info("hi");
        logger.warn("hi");
        logger.error("hi");
    }
}

Expected:

09:34:27.298 [main] INFO com.example.entry.Main - hi
09:34:27.298 [main] WARN com.example.entry.Main - hi
09:34:27.298 [main] ERROR com.example.entry.Main - hi

Output:

09:34:27.296 [main] DEBUG com.example.entry.Main - hi
09:34:27.298 [main] INFO com.example.entry.Main - hi
09:34:27.298 [main] WARN com.example.entry.Main - hi
09:34:27.298 [main] ERROR com.example.entry.Main - hi
