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

      Luciano,

I suspect that you are pulling in an older version of jcl-over-slf4j. 
You can use the dependency plugin to see all dependencies. The command is:

mvn dependency:tree

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>

Hello.
I am trying to integrate Logback for the first time in a project of
mine, and i'm having such a hard time trying to use it along with
Spring 3.0.5.
I declared jcl-over-slf4j dependency so it replaces commons-logging
used by spring-core, but it seems like something is missing or wrong:
java.lang.NoSuchMethodError:
org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;[Ljava/lang/Object;Ljava/lang/Throwable;)V
  at
org.apache.commons.logging.impl.SLF4JLocationAwareLog.info(SLF4JLocationAwareLog.java:159)
  at
org.springframework.jca.context.SpringContextResourceAdapter.start(SpringContextResourceAdapter.java:151)
...
Here're my logging dependencies (No commons-logging or log4j are being
used):
      <dependency>
      	<groupId>ch.qos.logback</groupId>
      	<artifactId>logback-core</artifactId>
      	<version>0.9.28</version>
      	<type>jar</type>
      	<scope>runtime</scope>
      </dependency>
      <dependency>
      	<groupId>ch.qos.logback</groupId>
      	<artifactId>logback-classic</artifactId>
      	<version>0.9.28</version>
      	<type>jar</type>
      	<scope>runtime</scope>
      </dependency>
      <dependency>
      	<groupId>org.slf4j</groupId>
      	<artifactId>slf4j-api</artifactId>
      	<version>1.6.1</version>
      	<type>jar</type>
      	<scope>runtime</scope>
      </dependency>
      <dependency>
      	<groupId>org.slf4j</groupId>
      	<artifactId>jcl-over-slf4j</artifactId>
      	<version>1.6.1</version>
      	<type>jar</type>
      	<scope>runtime</scope>
      </dependency>
Any thoughts about what may be wrong?
Thank you
Luciano
