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
