Android gradle Copy from more that one directory into one .jar

Question

I want to copy from more than one directory int one .Jar file:

So that all the .class files in both directories are bundles into one .jar file, is this possible?

task makeJar(type: Copy)
    from('directory1') && (directory2)
    into('another directory')
    include('classes.jar')

I can copy from one directory like this:

task makeJar(type: Copy)
    from('directory1')
    into('another directory')
    include('classes.jar')

Have you seen my answer? Also, did you want a .jar of your sources(.java) as well? — Jared Burrows, Apr 29 '15 at 19:27
@JaredBurrows, Yes I just did, the problem is I want to copy 2 separate **classes.jar** from different directories and make one **FILE.jar** from both of them, in such a way that all **.classes** that are contained in them are now contained in one .jar — Sbonelo, Apr 29 '15 at 21:01
@JaredBurrows Your answer copies correctly, but I cannot merge the two classes.jar into one. The directory that I copy into always contains the last classes.jar that I copied. — Sbonelo, Apr 29 '15 at 21:10
Why do you want the `.class` files? are you trying to make a compiled `.jar` of your project? — Jared Burrows, Apr 29 '15 at 21:23
