Problem with widgetset Vaadin7

rlalaoui · February 24, 2025, 9:19am

Hi,

I have a problem with my project who was developped in Vaadin 7. When i want launch my application, he ask me to compile widgetset. I use Eclipse for developpement and you removed the pluging Vaadin with the button Widgetset and the button to compile the theme.

I found another solution with maven, i opened a cmd and write this command : mvn vaadin:compile and mvn vaadin:compile-theme. It work and write in green BUILD SUCCESS, but when i launch the application, i have always this message

What can i do to find a solution ?

Best regard.

That plugin should still exists in the Eclipse Marketplace.

Another way to compile the widgetset is to use maven plugin:

See example

github.com

TatuLund/vaadin-create23/blob/master/vaadincreate-ui/pom.xml#L172


      
                      to compile a separate widgetset for production mode. -->
                  <attachClasses>true</attachClasses>
                  <!-- Exclude some unnecessary files generated by the 
                      GWT compiler. -->
                  <packagingExcludes>WEB-INF/classes/VAADIN/gwt-unitCache/**,
                      WEB-INF/classes/VAADIN/widgetsets/WEB-INF/**</packagingExcludes>
                  <failOnMissingWebXml>false</failOnMissingWebXml>
              </configuration>
          </plugin>
          
          <plugin>
              <groupId>com.vaadin</groupId>
              <artifactId>vaadin-maven-plugin</artifactId>
              <version>${vaadin.plugin.version}</version>
              <configuration>
                  <webappDirectory>${basedir}/target/classes/VAADIN/widgetsets</webappDirectory>
                  <style>OBF</style>
              </configuration>
              <executions>
                  <!-- You are free to mark this as permanently ignored in
                  Eclipse -->

And use vaadin-client-compiler

When i do in cmd command : mvn vaadin:compile

19 seconds sound too fast to me, usually widgetset compilation takes a minute.
