Error: "multiple SLF4J bindings" component from Talend Component Kit IntelliJ plugin

[Igor_V]

I try to use example from "Talend Component Kit tutorial" (https://talend.github.io/component-runtime/main/1.0.5/tutorial-create-my-first-component.html)

After compiling and deploying the component to Talend Open Studio, I recieve error:

SLF4J: Class path contains multiple SLF4J bindings.

SLF4J: Found binding in [jar:file:/C:/Data/TOS_ESB-Studio-V7.4.1/configuration/.m2/repository/org/apache/logging/log4j/log4j-slf4j-impl/2.12.1/log4j-slf4j-impl-2.12.1.jar!/org/slf4j/impl/StaticLoggerBinder.class]

SLF4J: Found binding in [jar:file:/C:/Data/TOS_ESB-Studio-V7.4.1/configuration/.m2/repository/org/talend/sdk/component/slf4j-standard/1.29.0-SNAPSHOT/slf4j-standard-1.29.0-SNAPSHOT.jar!/org/slf4j/impl/StaticLoggerBinder.class]

SLF4J: See http://www.slf4j.org/codes.html# multiple_bindings for an explanation.

SLF4J: Actual binding is of type [org.apache.logging.slf4j.Log4jLoggerFactory]

I insert in pom.xml extensions from http://www.slf4j.org/codes.html# multiple_bindings :

 <dependencies>

  <dependency>

   <groupId>org.talend.sdk.component</groupId>

   <artifactId>component-api</artifactId>

   <version>1.34.1</version>

   <scope>provided</scope>

   <exclusions>

    <exclusion>

     <groupId>org.slf4j</groupId>

     <artifactId>slf4j-log4j12</artifactId>

    </exclusion>

    <exclusion>

     <groupId>log4j</groupId>

     <artifactId>log4j</artifactId>

    </exclusion>

   </exclusions>

  </dependency>

 </dependencies>

But error remained the same. 

Who can HELP!!!!!

Hi @Grapeus Grapeus​ ,

run `mvn dependency:tree` to see from where is coming the dependency and exclude it. btw, in itself component-api has no slf4j dep.

best regards

Yes, in Idea the result of mvn dependency:tree:

com.tutorial:TMPLTDDD:jar:0.0.1-SNAPSHOT

[INFO] \- org.talend.sdk.component:component-api:jar:1.34.1:provided

[INFO]  +- org.apache.geronimo.specs:geronimo-annotation_1.3_spec:jar:1.2:provided

[INFO]  +- org.apache.geronimo.specs:geronimo-json_1.1_spec:jar:1.3:provided

[INFO]  \- org.apache.geronimo.specs:geronimo-jsonb_1.0_spec:jar:1.2:provided

No mention of slf4j.

But when I insert the example exported from Idea into the Talend job, I get the error described above after run.
