I just ran into this problem today.

Yes, Eclipse will create the Manifest for you, but it's really a joke.

It only includes the line Manifest-Version: 1.0. I have not figured out how to make it add my Main class, so I created my own MANIFEST.MF file, added it to my project main directory (not src and not lib). Then, when I go to Export > JAR File, hit Next all the way to the end (do not hit Finish too early) and click the option to select manifest from project. Select the Manifest file you just added to your project. Make sure the Manifest has the path to your Main class (e.g. com.company etc). For example this is how a basic Manifest file would look like:

Manifest-Version: 1.0
Created-By: 1.6.0 (Sun Microsystems Inc.)
Main-Class: MyPackage.MyClass

I tried @Michael's method but I ended up with no class files left in my JAR and only Manifest files.. oh well. My above method works well.
