TouchKit (4.1.0) + Vaadin (7.6.1) - NoClassDefFound

Flow

Hi,

I get the following exception when trying to run an app with TouchKit:

These are my dependencies (I’m using Gradle):

dependencies {

// Vaadin
providedCompile 'javax.servlet:javax.servlet-api:3.0.1'
providedCompile 'com.vaadin:vaadin-client-compiler:7.6.1'

compile 'com.vaadin:vaadin-client:7.6.1'
compile 'com.vaadin:vaadin-client-compiled:7.6.1'
compile 'com.vaadin:vaadin-push:7.6.1'
compile 'com.vaadin:vaadin-server:7.6.1'
compile 'com.vaadin:vaadin-themes:7.6.1'

// Email
compile 'javax.mail:javax.mail-api:1.5.5'

// Database
compile 'com.google.code.gson:gson:2.6.1'
compile 'org.mongodb.morphia:morphia:1.1.0'

// EventBus
compile 'net.engio:mbassador:1.2.4'

// For Markup
compile 'org.pegdown:pegdown:1.6.0'

// touchkit
compile 'com.vaadin.addon:vaadin-touchkit-agpl:4.1.0'

// Testing
testCompile 'junit:junit:4.12'
}

My servlet is pretty simple (I’m trying to modify from my currently desktop only app):

[code]
@WebServlet(value = “/*”, asyncSupported = true)
//@VaadinServletConfiguration(
// productionMode = false,
// ui = FalkirkRPGDesktopUI.class,
// heartbeatInterval = 60)
public class FalkirkRPGServlet extends TouchKitServlet {

private FalkirkRPGUIProvider uiProvider = new FalkirkRPGUIProvider();

@Override
protected void servletInitialized() throws ServletException {
super.servletInitialized();
getService().addSessionInitListener((SessionInitListener) event → event.getSession().addUIProvider(uiProvider));
}

}
[/code]Any ideas?

Thanks in advance. :slight_smile:

So I don’t know if this is a difference between Gradle and Maven, but changing line 5 above to this fixed the problem:

compile 'com.vaadin:vaadin-client-compiler:7.6.1'
