REST Assured: missing class that's (apparently) not missing

Here's my simple code:
import static com.jayway.restassured.RestAssured.get;
public class testget {
public static void main(String[] args) {
Response countryName = get("http://maps.googleapis.com/maps/api/geocode/json?latlng=45.2542285874,30.2564857&sensor=false");
System.out.println(countryName);
System.exit(0);
}
}
When running, I get the following error:

But the Rest Assured lib is loaded, otherwise the get method wouldn't even be called... What could it be?
I'm using Rest Assured 2.8.
Update:
I'm using Eclipse to run it, and the classpath has, besides the default Java/Eclipse content, the path to the .jar file of Rest Assured and it's dependencies, as listed on their website.
Dependencies list on the bottom of the page (all added to the classpath).

driven off the jar file compression

How to run a Sikulix.class ?
This is the error I'm getting.

The class you want to run is apparently org.sikuli.ide.SikuliIDE. You need to set the classpath to the top folder and not to the package folder and use the qualified class name.
D:\test_sikuli\sikulix>java -cp D:\test_sikuli\sikulix org.sikuli.ide.SikuliIDE

Exception in thread "main" java.lang.SecurityException: Invalid signature file d igest for Manifest main attributes

I have an application that when run in the IDE (Netbeans 8) works fine. The program makes use of 4 external .jar libraries. It also has a virtual machine argument pointing to a DLL. When I try to execute the .jar from the command line I get an error. This leads me to believe that there is a classpath issue.
This is the error itself:

I have used a workaround to get around this problem because I couldn't figure out a solution. I opened all of the JAR files that my application depends on and removed the META-INF/.DSA and META-INF/.SF files

Below is the project structure, which shows the classpath-
Is there any dependencies missing?

It seems your code can not find the class:
Caused by: java.lang.ClassNotFoundException: org.apache.xerces.dom.ElementNSImpl
from ODF Toolkit
Note: ODFDOM requires Apache Xerces. The jar file xercesImpl.jar also must exist in a folder lib next to odfxsltrunner.jar file, or it must be in the classpath. The ODF XSLT Runner NetBeans projects includes a reference to xersesImpl.jar in the runtime classpath which has to be adapted after checking out the project.
