How to combine multiple JARs into one JAR

hi all,

I have 2 JAR files. For example a.jar and b.jar.
a.jar is the library to b.jar. Can I combine these JAR files so that I can run it using one JAR?
Thanks for help.

Hi,

You can use fatjar to do your job. Please click here for more info.

Or jarjar, which does the same thing (as well as provide renaming/shading options) without having to be used as a plugin.

have you use this before because I'm not familiar with all this. Thanks for the replied.

Hi david, thanks for the replied.
I've downloaded this but i was confuse. there's not much guide on how to use it.

Not sure what kind of information you need.

What else?

You could also use Apache Maven, which is the preferred solution for larger projects imho.

Note that using an Eclipse plugin like FatJar will be a lot easier than learning Maven...

Suggesting Maven seems like a bit of overkill for what is a relatively simple requirement--that would require a complete overhaul of the original poster's project.

Indeed it may be overkill for a small project; however, Maven has features that would make the task fairly straight forward should other features that it offers be desirable.
