I have followed multiple links on SO and other sources on the internet and modified my logback.xml but it is still not working. Please help.

I have a web application in Maven using Java 1.7 and Spring 4.3.13.RELEASE.

logback.xml under src/main/resources

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE configuration>

<configuration>

    <property name="log.folder" value="/logs" />
