Deployment on Tomcat: Constraint violation when resolving method "org.slf4j.impl.StaticLoggerBinder.getLoggerFactory()Lorg/slf4j/ILoggerFactory;"

Question

I'm deploying Shibboleth IdP 3.1.1 on Tomcat 8.0.22, but I receive this error:

Information about the java version:

java version "1.7.0_80"
Java(TM) SE Runtime Environment (build 1.7.0_80-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)

I put in $CATALINA_HOME/lib the jars: slf4j-api-1.7.12.jar, slf4j-log4j12-1.7.12.jar and nlog4j-1.2.14.jar

But that does not solve the problem. I tried put org.slf4j as a dependency in maven, but don't work too.

Is there a way to resolve this exception? Thanks for any suggestion.

This mean you probably have two different librairies of slf4j in your war

org/slf4j/impl/StaticLoggerBinder, have different Class objects for the type LoggerFactory; used in the signature

You can use that command to find slf4j dependencies injected in your application.

mvn dependency:tree -Dverbose -Dincludes=commons-collections

resolving conflicts using the dependency tree

And Exclude dependancies in Maven:

<dependency>    
    [...]
    <exclusions>
        <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
        </exclusion>
    </exclusions>
<dependency>

You can also unzip your war file and look in WEB-INF/lib/ to find the different versions of slf4j that you have.

Perhaps one can be shipping with Tomcat. – Piotr Findeisen Jul 03 '15 at 20:02
Thanks , error gone , now it says java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory. Any idea? – Ricardo T. Macedo Jul 04 '15 at 22:49
Now you excluded too many. Your application try to find the class org.slf4j.LoggerFactory but it's not there. – bodyjares Jul 05 '15 at 00:16
I had this issue with Tomcat 7, I had another slf4j version in the $CATALINA_HOME/lib directory, so I added org.slf4j slf4j-api ${sl4jVersion} provided to my pom.xml for the slf4j dependency. – Brad Rippe Jan 03 '17 at 22:58

This problem may be because there is a jar in the servlet container (Ex Tomcat).

For example:

someone had kept some lib (In this case slf4j) in a tomcat's lib.
you deployed a new project to that tomcat.
In your new project, some of your dependencies have dependencies to that lib.
Then there is duplicated of the same jar in Tomcat and WAR of your new project

Then you get such an error message.

The way to solve this is just use "scope" to say that it is provided.

        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>1.7.6</version>
            <scope>provided</scope>
        </dependency>

By doing this, the WAR file will not include that dependency.

Problem solved. I used mvn dependency:tree to see the dependencies:

If you are using spring-boot-starter-web-1.5.1.RELEASE.jar,then you need to exclude jul-to-slf4j-1.7.22.jar,jcl-over-slf4j-1.7.22.jar.These two jar have conflict slf4j-api.
