Hello,
I’ve seen various forms of this error on other posts, but none of the resolutions seem to fit for my issue. I’m trying to add some add-ons to my existing Vaadin application. But before doing that, I just want to build the sample as a first attempt at using add-ons. I end up in an identical error on both my linux machine and my windows machine. I’ll indicate the steps followed by the error.
Enviroment:
Apache Maven 3.0.4 (r1232337; 2012-01-17 11:44:56+0300)
Maven home: C:\Program Files\Apache Software Foundation\apache-maven-3.0.4
Java version: 1.7.0_07, vendor: Oracle Corporation
Java home: C:\Program Files\Java\jdk1.7.0_07\jre
Default locale: en_US, platform encoding: Cp1252
OS name: “windows 7”, version: “6.1”, arch: “x86”, family: “windows”
Commands:
– First I build the project (I realize the parameters below should be customized, it doesn’t matter for the example.)
mvn archetype:generate -DarchetypeGroupId=com.vaadin -DarchetypeArtifactId=vaadin-archetype-sample -DarchetypeVersion=LATEST -DgroupId=your.company -DartifactId=project-name -Dversion=1.0 -Dpackaging=war
– I modify POM.xml to use Java 1.7. And modify the maven compiler plugin to explicitly set a version so that maven does not complain
...
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.7</source>
<target>1.7</target>
<compilerVersion>1.7</compilerVersion>
</configuration>
<version>2.5.1</version>
</plugin>
...
– Then I run the add-on compilation sequence
mvn gwt:clean
mvn vaadin:update-widgetset
mvn gwt:compile
mvn package
mvn jetty:run
Error:
Once I load http://localhost:8080/project-name I get the following error:
I notice that the colorpicker isn’t in the deployement folder’s lib directory so I add
<dependency>
<groupId>org.vaadin.addons</groupId>
<artifactId>vaadin-colorpicker</artifactId>
<version>1.1.0</version>
</dependency>
to the pom. And then run the commands again, this time the jar is in the lib folder. But the error is still the same.
I think my web.xml and *.gwt.xml files are correct… well they are as the vaadin-archetype-sample set them.

Going to the address [quote]
http://localhost:8080/project-name/VAADIN/widgetsets/your.company.gwt.ColorPickerWidgetSet
[/quote] Give the following list:
which I guess should tell me that the compilation process may have worked and the configuration is f*ed up somewhere. There are no [ERROR]
or [WARNING]
lines from maven except the ones from mvn:update-widgetset which I understand is ok.
A zip of the cleaned project is attached.
My gratitude to anyone that can help before I loose my sanity.
