API shipped as zip

Hello,

I am building a multi dependencies application. But i encounter a problem : one API i do want to use is provided as a zip instead of a jar and thus the IDEA does not recognize it when i want to load it as a library.

I find it quite disturbing since the same API author provides an other API that i also use as a jar. Is there something to do in Intellij for this case or do i have to build my own jar by extracting the zip and building a jar with the source ( i don't know how an API should be built so if someone could explain me this if this is the only solution, that would be great)

Thanks.
