Unable to compile a widgetset

Flow
1

Hi all.

It makes 2 days i´m trying to compile a widgetset in my project, but i´m unable to do.

The path i did follow was to create a new project using maven vaadin archetype, add Vaadin Charts to this project and compile the widgetset in this project. This step is working.

So, i tried to copy everything in this project to my current project, but it´s not working.

Here is the status of my current project, where i´m unable to compile the widgetset.

  • There is a file called “br.com.personalsoft.metas.AppWidgetSet.gwt.xml”.

<module>
	<inherits name="com.vaadin.DefaultWidgetSet" />
	
	<inherits name="com.vaadin.addon.charts.Widgetset" />
	
	<inherits name="com.vaadin.addon.timeline.gwt.TimelineWidgetSet" />
</module>
  • Here is my web.xml file. The only remarkable difference compared to web.xml of the new project is “productionMode” and a listener class.

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	</servlet>
	<servlet-mapping>
		<servlet-name>App</servlet-name>
		<url-pattern>/*</url-pattern>
	</servlet-mapping>
</web-app>
  • Here is my pom.xml file. The main differences compared to the pom.xml file of the new project are:
    – My project codepage is Cp1252
    – My project has more dependencies
    – My project uses java 7
    – My project has a “resource” section, where i exclude *.java and *.app2 files from the build
    – Everything else is identical to the new project´s pom.xml

</project>

First, i run

mvn vaadin:update-widgetset

and it is able to find my “AppWidgetSet.gwt.xml” file and update it.

Then, i tried many alternatives, but the one that is working in the new project is

 mvn install

So i´m trying it in my current project, but i get this error:

I have the same problem when executing “Compile Vaadin widgets” option in Vaadin eclipse plugin.
At first the message was:

Could not find or load main class com.vaadin.tools.WidgetsetCompiler

Then I change the project’s Ivy configuration removing conf=“widgetset-compile->default” from vaadin-client-compiler dependency.
After that, the result of widgetset compilation was:

java.lang.NoSuchFieldError: warningThreshold

It seems that the same issue occurs when compiling widgets from an Vaadin eclipse plugin.

Regards,
Jacek

I have the same problem as Jacek. I want to use the RatingStars add-on, but i can not compile the widgetset. Following exception will be thrown:


java.lang.NoClassDefFoundError: com/vaadin/tools/WidgetsetCompiler

Could not find the main class: com.vaadin.tools.WidgetsetCompiler.  Program will exit.

Widgetset compilation failed

I installed vaadin 7 over the eclpise marketplace and used the plugin button to start the widgetset compilation.

Check that you have vaadin-client-compiler in your project dependencies (Ivy configuration) - normally it should be there, but your error message looks like it is missing.

If that is not the issue, information about the versions of Vaadin and the plugin and a copy of your dependency management configuration might help in finding out what is the issue.

5

If still unresolved: Try replacing the vaadin-client-compiled dependency (which is not needed when you use your own widgetset) with vaadin-client-compiler. Normally the plugin adds it automatically, but maybe one of your transitive dependencies (vaadin-charts?) would specify a different version of it. An explicit dependency of an entry in dependencyManagement should force it to use the correct version.

Hi I am getting below exception when try to compile wegetset in eclipse,

Executing compiler with command line:

That is my problem too. Can somebody help me?

Hi , if you are using eclipse then just check the following

  1. Ivy libraries are above every other libraries ( just below src and it is checked ) in java build path
  2. just below are the web app libraries and it is check as well
  3. clean - rebuild project and try again
10

I have had similar Error: Error: Could not find or load main class com.vaadin.tools.WidgetsetCompiler in Eclipse.

In my case helped to uncomment in pom.xm commented rows in dependencies:

<!-- Needed when using the widgetset optimizer (custom ConnectorBundleLoaderFactory).
  For widgetset compilation, vaadin-client-compiler is automatically added
  on the compilation classpath by vaadin-maven-plugin so normally there is
  no need for an explicit dependency. In Java 8 enable it -->
<dependency> <groupId>com.vaadin</groupId> <artifactId>vaadin-client-compiler</artifactId>
  <version>${vaadin.version}</version> <scope>provided</scope> </dependency>
<dependency>
11

For me, the solution was to resolve.
Right-click on project → Ivy → Resolve
. Takes a while as it re-downloads everything it needs, but then that problem went away. Now I just need to figure out why Tomcat won’t let me Republish.

12

Thank a lot for the hint. I had the very same problem using the
VLeaflet Example

Unlike stated in the comment, only after including the dependency it started to download the vaadin-client-compiler (using Java 1.6).

13

Worked perfect, Thanks!

14

ya for me also Working Fine . Thanks

Jacek Hełka:
I have the same problem when executing “Compile Vaadin widgets” option in Vaadin eclipse plugin.
At first the message was:

Could not find or load main class com.vaadin.tools.WidgetsetCompiler

Then I change the project’s Ivy configuration removing conf=“widgetset-compile->default” from vaadin-client-compiler dependency.
After that, the result of widgetset compilation was:

java.lang.NoSuchFieldError: warningThreshold

It seems that the same issue occurs when compiling widgets from an Vaadin eclipse plugin.

In my case removing conf=“widgetset-compile->default” from ivy.xml resolved the problem, and the Widgestset got compiled.
