<format> 

dir değeri kullanılır. Açıklaması şöyle

we set the format to dir. This means the resulting artifact will be a folder with JAR files in it. As an alternative, you can change that to jar and get one BIG jar file with all resources and dependencies

<dependencySet>

 Açıklaması şöyle. Kendi kodum olan dependency'lerimi kopyalamıyorum, çünkü bunlar moduleSet ile kopyalanacak

useProjectArtifact: We say that do not use the artifact from the module itself
outputDirectory: Put the dependencies in the folder named shared  
unpack: keep them as JAR files instead of unpacking 
exclude: exclude the app and tools from the dependency list.
