Simplified Vaadin add-on development with Maven and Jetty

Jetty Vaadin Add-on

Jetty Vaadin is a Vaadin add-on that allows you to run a Jetty Server for a Vaadin application in Java.

Creating Vaadin add-ons

Jetty Vaadin Add-on is highly useful when developing Vaadin add-ons. It simplifies the development cycle by allowing you have both, the code for the add-on itself and the code for any demo application, in the same project.

Follow this instructions to get a single module Vaadin add-on Maven project:

1) Create a Vaadin project using the vaadin-archetype-widget Maven archetype (see this).

2) Remove the generated demo module and copy the src directory, the assembly directory, and the pom.xml file in the addon module to the root directory and remove the addon directory (this will overwrite the pom in the root directory).

3) Add the jetty-vaadin dependency using <scope>test</scope> in your pom.xml.

4) Add the vaadin-themes dependency in your pom.xml if required (most of the time it is):


5) If a custom widgetset is required, add the vaadin-maven-plugin. See this.

6) If no custom widgetset is required, add the vaadin-client-compiled:


7) Implement a UI in the test directory. Use the @Widgetset annotation if required:

public class TestUI extends UI { ... }

8) Add a standard main method to the UI implementation and create and start a new VaadinJettyServer:

public static void main(String[] args) throws Exception {
    VaadinJettyServer server = new VaadinJettyServer(8080);

9) Build the project (mvn clean package).

10) Run the standalone Java application from your IDE (the IDE will manage the classpath) or with Maven:

mvn exec:java -Dexec.mainClass="com.example.TestUI" -Dexec.classpathScope=test

If you are using Linux or Mac, you can copy and paste the following in a terminal and continue from step 3:

mvn -B archetype:generate -DarchetypeGroupId=com.vaadin -DarchetypeArtifactId=vaadin-archetype-widget -DarchetypeVersion=7.6.8 -DgroupId=com.example -Dpackage=com.example -DartifactId=example -DreleaseVersion=1.0-SNAPSHOT
cd example
rm -rf example-demo/
cp -r example-addon/src .
cp -r example-addon/assembly .
cp example-addon/pom.xml .
rm -rf example-addon/
