[logback-user] Spring -> SLF4J -> Logback

[David Roussel]

Luciano,

The problem is probably because you have commons-logging the class path. 
Use the maven dependencies plugin to find where it is coming from.  It'll
definately be coming from spring, but possibly other places.

Then try this:


			<dependency>
				<groupId>org.springframework</groupId>
				<artifactId>spring-core</artifactId>
				<version>${spring-version}</version>
				<exclusions>
					<exclusion>
						<groupId>commons-logging</groupId>
						<artifactId>commons-logging</artifactId>
					</exclusion>					
				</exclusions>
			</dependency>
