Embedded Jetty+Vaadin. Cannot use add-ons.

Hello.
I created some little "Intellij Idea" project with Vaadin, but i cannot add add-ons.

After start i see a page with text:
"Widgetset 'com.vaadin.DefaultWidgetSet' does not contain an implementation for com.alsnightsoft.vaadin.MaskedField. Check the connector's @Connect mapping, the widgetset's GWT module description file and re-compile your widgetset. In case you have downloaded a vaadin add-on package, you might want to refer to add-on instructions."

I looked at instructions link, but cannot fully understand how to fix it.
Please review my project and suggest me how to use add-ons.

Thanks!

Hi, 
you should add vaadin plugin configuration to your pom.

<plugin>
  <groupId>com.vaadin</groupId>
  <artifactId>vaadin-maven-plugin</artifactId>
  <version>${vaadin.plugin.version}</version>

  <configuration>
    <extraJvmArgs>-Xmx512M -Xss1024k</extraJvmArgs>
    <webappDirectory>${basedir}/target/classes/VAADIN/widgetsets</webappDirectory>
    <draftCompile>false</draftCompile>
    <compileReport>false</compileReport>
    <style>OBF</style>
    <strict>true</strict>
  </configuration>

  <executions>
    <execution>
      <goals>
        <goal>update-theme</goal>
        <goal>update-widgetset</goal>
        <goal>compile</goal>
        <goal>compile-theme</goal>
      </goals>
    </execution>
  </executions>
</plugin>

You can also omit the executions confiiguration and manually run widgetset compilation via maven.

See here and here for futher information

Thanks, Marco!
I add this XML to pom.xml, but it did not help. If i start/debug application over Run/Debug Idea's buttons - the problem still here.
On start goal 'vaadin:compile' it only outputs "[WARNING] GWT plugin is configured to detect modules, but none were found."
On start goal 'vaadin:update-widgetset' it create ${basedir}/target/generated-resources/gwt/AppWidgetset.gwt.xml with content:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 2.5.1//EN" "http://google-web-toolkit.googlecode.com/svn/tags/2.5.1/distro-source/core/src/gwt-module.dtd">
<module>
    <inherits name="com.vaadin.DefaultWidgetSet"/>
    <inherits name="com.librishuffle.WidgetSet" />
    <inherits name="com.alsnightsoft.vaadin.MasketfieldWidgetset" />
</module>

It only works if i start lifecycle 'package'. It generates many other folders and application starts properly.
Do i need to always start lifecycle 'package' or there is simplest procedure, that i can link with 'Make' step of IntelliJ Idea?

I think i understand some more at now...
When i use lifecycle 'package'  then Maven generates correct JAR file with dependent libs, include Vaadin add-ons.
So, there is ready solution for generate final JAR.
But when i develop my project i will use sometime lifecycle 'package' for generate client parts of Vaadin add-ons.

Hi, I think you can also avoid to run the whole package phase.
Try using this args for maven task in make step

vaadin:update-widgetset process-resources vaadin:compile

This will only recompile the widgetset when it is not found in the target directory (so at first launch or after a maven clean)
In this case you can remove the executions configuration for vaadin maven plugin
