Also, you need to use the maven-shade-plugin to package the artifact in an uber-jar.

How can i exclude ‘shade’ plugin and use ‘maven-jar-plugin’ ‘maven-dependency-plugin’ instead?

It works with Vaadin 8, for example:

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>

                            <addClasspath>true</addClasspath>
                            <classpathPrefix>libs/</classpathPrefix>
                            <classpathLayoutType>simple</classpathLayoutType>
                            <mainClass>our.Application</mainClass>
                        </manifest>

Cool! Thanks for sharing the solution.

Hmm. I play with annotations @Push, @Theme and @Route. I create some classes with that annotations, all works fine. Then i wanted to disable some classes from routing and simply comment @Route annotation. After that all app restarts brought me to “HTTP ERROR 503. Service Unavailable” message. All other views become unavailable too. I tried to play with some variants with comment/uncomment annotations and understand that i should not use @Push or @Theme annotations with commented out @Route.

Vaadin 14 brings new pain… Is there anybody know wehere to get working Jetty-embedded demo project?

Martin602 · July 9, 2019, 7:30am

It’s actually less pain! You should use npm-based frontend build. For this you need to remove all jars related to webjar content from the classpath. Then you need to have the following Servlet and set the following init configuration:

asyncSupported=true
compatibilityMode=false

However, there is some serious build trouble with Vaadin 14 RC3, you should use RC2 for now!

SERVLET:

public class VaadinJettyEmbeddedServlet extends VaadinServlet {
	
	private static final long serialVersionUID = -8665721849295105766L;

	@Override
	public void init(ServletConfig servletConfig) throws ServletException {
		super.init(servletConfig);
		
		this.getService().setClassLoader(VaadinJettyEmbeddedServlet.class.getClassLoader());
	}
	
	@Override
	public boolean serveStaticOrWebJarRequest(HttpServletRequest request, HttpServletResponse response) throws IOException {
		if(request.getRequestURI().startsWith("/VAADIN/static")) {
			URL resource = this.getClass().getClassLoader().getResource("/META-INF/resources" + request.getRequestURI());
			if(resource != null) {
				String mimetype = request.getServletContext().getMimeType(request.getRequestURI());
				if(mimetype != null) response.setContentType(mimetype);
				
				InputStream inputStream = resource.openStream();
				try {
					return IOUtils.copy(inputStream, response.getOutputStream()) > 0;
				} finally {
					IOUtils.closeQuietly(inputStream);
				}
			}
		}
		return super.serveStaticOrWebJarRequest(request, response);
	}
}

How can i do it with Maven?

Hi, I’ve created an example project which runs embedded Jetty on Vaadin 14.1: https://github.com/mvysny/vaadin14-embedded-jetty
