[Soot-list] Exception in thread "main" java.lang.RuntimeException:, There is no main class set!

[Cheng Zhang]

Hi,

So far as I know, one workaround is to add a main method by hand.
It works fine when there are not so many custom entries.

A complete solution is described on Eric's website:

Best,
Cheng
