Can i merge many jar files into one jar file

Question

I have several JAR files that I have to add to the classpath in Eclipse.

Is it possible to combine 30 files into one file and include this file?

Answer 1

You might want to watch jarjar .

If you use the ant task, you can also go to zipgroupfileset:

<zip destfile="jarlibrary.jar">
    <zipgroupfileset dir="lib" includes="*.jar"/>
</zip>

Answer 2

You can, but I don’t think it would be nice to do it. Three possible causes, and undoubtedly more of them:

• It's hard to see where any one compound file comes from.
• This makes it difficult to replace just one library.

Answer 8

Jar files are just ZIP files, so you can try to unzip all the jars, put all the files together, and then ZIP files again.
