Alternative classpath settings apart from fatjar

[Harald Kirsch]

I am trying to use tika-parsers-1.4.jar in a self-build fat jar, meaning 
I just unjar all jars into one directory and jar the result into one fat 
jar.

The problem is, that this produces an unreliable META-INF, so just 
before running jar, I delete the META-INF directory.

This seemed to work, except that tika-parsers does not work anymore. No 
error, no exception, no log, it just returns nothing. And I can boil 
this down to the META-INF.

Now, there might be a way to hand-craft a fat jar that works. However I 
wonder if there is a better way  to add additional jars to a topology?
