OK, I tried make, but the makefile doesn't support Visual Studio (only 
on Windows Phone, not on Windows 7). So I guess I'll have to start over 
on a Linux box, because a mingw build will most certainly be 
incompatible with the maven-compiled stuff, which used Visual Studio. 
And anyway, mingw64 isn't supported either, only mingw32. cmake is not 
that bad, after all...

When Tobias tried his code on my machine, we had a similar problem. We 
solved it by adding some paths explicitly (vigra-imglib2/target/classes 
and 
$HOME/.m2/repository/net/imglib2/imglib2/2.0.0-SNAPSHOT/imglib2-2.0.0-SNAPSHOT.jar). 
I applied the same change to your pom file, and got a bit further. The 
error message is now

[ERROR] Error: Could not find class file for 
'net.imglib2.vigra.VigraImg3DUnsignedByte'.

No, there is no duplication. The two approaches are completely 
complementary -- yours is for embedding Java in a VIGRA program, and 
Tobias' is to call VIGRA code from Java. You can have a look at
   https://github.com/tpietzsch/vigra-imglib2/tree/buffer
