Junit is not working in Maven Project

I wrote the following code to read the contents of the arxml file.
#Test
public void second() throws IOException {
private XMLResource resource;
String file = "E:\\Input\\ArText_0001.arxml";
AutosarResourceSetImpl resourceSet = new AutosarResourceSetImpl();
Autosar40ResourceFactoryImpl resourceFactory = new Autosar40ResourceFactoryImpl();
URI uri = URI.createFileURI(file );
Map<?, ?> options = null;
resource = (XMLResource) resourceFactory.createResource(uri);
resource.load(options);
resourceSet.getResources().add(resource);
}
I run the project using clean verify goal , In eclipse its working fine but using maven from command line I am getting the following exception.
java.lang.StackOverflowError: null
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClass(ClassLoader.java:763)
Finally i got know I am facing the problem in resource.load(option).Instead of option = null I tried the following way also
option.put(Resource.Factory.Registry.DEFAULT_EXTENSION,new Autosar40ResourceFactoryImpl())
But now also i am getting same exception.Please help me to solve this one?

Newly created JUNIT class not found exception (Class not found com.pearson.aimswebplus.controller.TestNavAssignmentListControllerTest)

I created a java file TestNavAssignmentListControllerTest. codes as follows
public class TestNavAssignmentListControllerTest extends

#Autowired
private TestnavAssignmentListController testnavAssignmentListController;
#Test
public void searchOk(){
String params = "aimswebId=1168&roster=RCM3MA==&minGrade=0&maxGrade=7&measureCode=&type=&schoolYearVal=2015&benchmarkPeriodId=2&studentsWithNewStatus=0&page=0&size=0&sort=studentName&order=asc&username=manager&assignmentIds=1602,1723,1829,2437";
TestnavAssignmentListDto listDto = (TestnavAssignmentListDto) when().get(BASE_URL + "/query/testnavAssignments?" + params) .as(TestnavAssignmentListDto.class);
assertNotNull(listDto);
}
when I try to run as Junit Test it throws

Class Not Found Exception When Creating New Instance Of Class Inside of Jar - Java

I am trying to create a new instance of a class to invoke a method in Java. But because the class is inside a jar (Which loads just fine), The class cannot. This causes a ClassNotFoundException to be thrown. Could someone please tell me how to fix this?
Code:
private static void loadClassFromJar(String PluginJar) throws MalformedURLException, ClassNotFoundException, InstantiationException, IllegalAccessException, NoSuchMethodException, SecurityException, IllegalArgumentException, InvocationTargetException {
File PluginFile = new File("./debug/plugins/DiamondCorePlugin.jar");
URL[] PluginURLs = { PluginFile.getAbsoluteFile().toURI().toURL() };
URLClassLoader ClassLoader = URLClassLoader.newInstance(PluginURLs);
Class<?> PluginClass = ClassLoader.loadClass("net.trenterprises.diamondcore.plugin.Main");
Method EventMethod = PluginClass.getMethod("onEnable");
EventMethod.invoke(PluginClass.newInstance());
}

Found the problem! It turned out that the class was loading just fine, but in another class that tried to get the classes name, becuase the class was in a JAR file. It could not load! Thank you for all of the help immibiz and vanza!
