Spring always print logs at DEBUG level when running Maven - spring

Question

I am using slf4j, logback for logging in my Spring application. I have configured to exclude common-logging and add the jcl-over-slf4j bridge.
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<exclusions>
<exclusion>
<groupId>commons-logging</groupId>
<artifactId>commons-logging</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.12</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>jcl-over-slf4j</artifactId>
<version>1.7.12</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.1.3</version>
</dependency>
My logback.xml looks like the following:
<root level="INFO">
<appender-ref ref="STDOUT" />
</root>
<logger name="com.my" level="DEBUG" />
The problem is when running maven builds, classes from spring always prints in DEBUG level which pollutes the console with verbose information. This doesn't happen when running the app with Tomcat though.
Also, if I extend a class of Spring, e.g. HttpSessionRequestCache, logging statements from the Spring classes are executed, as if it get the level from the child class! This does happen when running with Tomcat.
How to make Maven honor the logback.xml configuration?
