Reflections is not working when using Jenkins

I've created a console app which gets dlls from folder and uses reflection in order to extract the methods out of each dll, it works fine on my local machine, but when I use this app from Jenkins server, I get error for each

file (could not be loaded: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.)

is that a known issue? what could be the problem?
