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

jar, java

Solution

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.

Problem

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 end. ``` import com.xuggle.mediatool.IMediaReader; import com.xuggle.mediatool.IMediaViewer; import com.xuggle.mediatool.IMediaWriter; import com.xuggle.mediatool.ToolFactory; public class TranscodingExample { private static final String inputFilename = "E:\\VIDEO\\Facebook.mp4"; private static final String outputFilename = "E:\\VIDEO\\Facebook.flv"; public static void main(String[] args) { // create a media reader IMediaReader mediaReader = ToolFactory.makeReader(inputFilename); // create a media writer IMediaWriter mediaWriter = ToolFactory.makeWriter(outputFilename, mediaReader); // add a writer to the reader, to create the output file mediaReader.addListener(mediaWriter); // create a media viewer with stats enabled IMediaViewer mediaViewer = ToolFactory.makeViewer(true); // add a viewer to the reader, to see the decoded media mediaReader.addListener(mediaViewer); // read and decode packets from the source file and // and dispatch decoded audio and video to the writer while (mediaReader.readPacket() == null) ; } } ``` Here I am getting an error ``` "Detected both log4j-over-slf4j.jar AND slf4j-log4j12.jar on the class path, preempting StackOverflowError.". ``` I have used both jar files as libraries in order to solve logging problems. How can this problem be solved?
