I have compiled a spring boot war and trying to deploy it to JBoss application server. There seems to be some conflict with jackson jars present in modules of my jboss with spring boot dependencies. this is what i have found when i run mvn dependency:tree -Dincludes=com.fasterxml.jackson.core

[INFO] com.newgen:omnipedia2:war:0.0.1-SNAPSHOT [INFO] +- com.fasterxml.jackson.core:jackson-databind:jar:2.11.0:provided [INFO] +- com.fasterxml.jackson.core:jackson-core:jar:2.11.0:provided [INFO] \- com.fasterxml.jackson.core:jackson-annotations:jar:2.11.0:provided 

In my jboss modules folder jackson jars of version 2.6 already exist. I have tried putting 2.9 version jars in tmodules also. that dos not works.

I have modified my pom.xml

<dependency>             <groupId>com.fasterxml.jackson.core</groupId>             <artifactId>jackson-databind</artifactId>             <scope>provided</scope>         </dependency>         <dependency>             <groupId>com.fasterxml.jackson.datatype</groupId>             <artifactId>jackson-datatype-jdk8</artifactId>             <scope>provided</scope>         </dependency>         <dependency>             <groupId>com.fasterxml.jackson.datatype</groupId>             <artifactId>jackson-datatype-jsr310</artifactId>             <scope>provided</scope>         </dependency>         <dependency>             <groupId>com.fasterxml.jackson.core</groupId>             <artifactId>jackson-core</artifactId>             <scope>provided</scope>         </dependency>         <dependency>             <groupId>com.fasterxml.jackson.core</groupId>             <artifactId>jackson-annotations</artifactId>             <scope>provided</scope>         </dependency> 

and in jboss server logs this error occurs
