I made a program with third party libraries like apache and i'm trying to put them all in a runnable .jar file. I searched a lot, and i found a program named "JarSplice - The Fat Jar Creator" but when i go to create the final jar i'm getting the error: 

Jar creation failed due to the following exception:
duplicate entry: org/apache/xmlbeans/xml/stream/Location.class

My 3rd party libs are:

poi-3.14-20160307.jar
poi-examples-3.14-20160307.jar
poi-excelant-3.14-20160307.jar
poi-ooxml-3.14-20160307.jar
poi-ooxml-schemas-3.14-20160307.jar
poi-scratchpad-3.14-20160307.jar
xmlbeans-2.6.0.jar

I dont see any duplicates :/ So what am i doing wrong? Is there any way to void this error? Any help will be highly appreciated!

  • I would highly suggest using [Maven](https://maven.apache.org/index.html) to create a JAR with dependencies. If you really do want a single JAR with all the class files in it, you can use the Maven [shade plugin](https://maven.apache.org/plugins/maven-shade-plugin/). – Adam Aug 19 '16 at 19:55
