How to autowire #service from external Jar in Spring - spring

Question

I am developing two spring based application(Ex app1 and app2) fully on Java configuration with Maven and no XML config.
Through Maven -WAR plugin , I have created Jar reference of app2 and using mvn install:install file I have binded the app2 jar with app1.
app2 - Its used to fetch inforamtion from data source.
I have autowired the app2 serive in app1 implementation class to fetch the details which was annotated with #Service in app2 application.
My first doubt is:
Both app1 and app2 have separate AppConfig.java file.Is it possible to simply autowiring one of the #Service which is availble in Jar format or else I need to define or import App2's AppConfig java file into App1's AppConfig.jave file.
I have tried with the simple autowired the external JAR #Service class and ended with error.
Kindly help me on what needs to be done to autowire external Jar's #Service to the
implementation class.
Below is my App1 repository class
#Repository
public class VehicleRepository {
#Autowired
VehicleService vehicleservice;
public Map<String, item> getAllTypes(String type) {
Vehicke vehicle = vehicleservice.getAllVehicle(type);
// handle response here...
} catch (Exception ex) {
// handle exception here
} finally {
}
return vehicleDetails;
}
}
VehicleService is available in external Jar.
VehicleService Class:
#Service
public class VehicleService {
public VehicleService() {
}
#Autowired
PortRepository portRepository;
#Autowired
MessageSource messageSource;
public Vehicle getAllVehicles(String type) {
List<Vehicle> cehicles = portRepository.getPorts();
return vehicle;
}

Let's make it simple.
Your App1 depends on App2.
So you use #Import(App2Config.class) class App1Config {}, that's it.
And by the way, instead of tricks with 'mvn install:install file' you can just use parent pom.xml with modules app1 and app2, and declare dependency of module app1 on module app2 in pom.xml <dependencies> section. You then run 'mvn install' to build your project.
