Detected both log4j-over-slf4j.jar AND slf4j-log4j12.jar on the class path, preempting StackOverflowError.

Question

I have used xuggle library in my project to trans code the video from mp4 to flv. I have used slf4j libraries also to support logging

Answer 1

For gradle

compile('org.xxx:xxx:1.0-SNAPSHOT'){
    exclude module: 'log4j'
    exclude module: 'slf4j-log4j12'
}

Answer 2

I got the solution

download Xuggler 5.4 here

and some more jar to make it work...

commons-cli-1.1.jar

commons-lang-2.1.jar

logback-classic-1.0.0.jar

logback-core-1.0.0.jar

slf4j-api-1.6.4.jar

You can check which dependencies xuggler needs from here:

Add this jars and xuggle-xuggler-5.4.jar to your project's build path and it s ready.

**version numbers may change

Answer 3

SBT solution stated above did not work for me. What worked for me is excluding slf4j-log4j12

//dependencies with exclusions
libraryDependencies ++= Seq(
    //depencies
).map(_.exclude("org.slf4j","slf4j-log4j12"))

Answer 4

So you have to exclude conflict dependencies. Try this:

<exclusions>
  <exclusion> 
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
  </exclusion>
  <exclusion> 
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
  </exclusion>
</exclusions> 

This solved same problem with slf4j and Dozer.

Answer 5

Encountered a similar error, this how I resolved it:

1. Access Project explorer view on Netbeans IDE 8.2. Proceed to your project under Dependencies hover the cursor over the log4j-over-slf4j.jar to view the which which dependencies have indirectly imported as shown below.

2. Right click an import jar file and select Exclude Dependency

3. To confirm, open your pom.xml file you will notice the exclusion element as below.

4. Initiate maven clean install and run your project. Good luck!

Answer 6

And for SBT : excludeDependencies += "log4j" % "log4j"
