Unusable in modular Java projects #242
Description
Since no module-info exists, nor does an Automatic-Module-Name exist in the MANIFEST.MF, the generated name of this library becomes "ergo.appkit.2.12" which is an invalid name because no part of it can start with a number.
Unfortunately, fixing that will not be enough because the dependencies of this library also do not come with a module name and result in invalid names being generated due to the strange library_2.12 format used by Scala.
However, that does not mean that appkit should not have an Automatic-Module-Name. For example, the scala standard library comes with one (scala.library).
The first step to rectifying this problem is to add an Automatic-Module-Name to appkit. It should be named org.ergoplatform.appkit in my opinion.
