Vaadin Widgetset Compilation Error After Vaadin8 Migration

Question

I just migrated my Vaadin project from 7.7.6 to 8.0.5. First I wanted to use the Vaadin8 migration tool but my IDE used too many vaadin.* imports so I just did it manually. After hours of work (compatibility package imports) the maven build worked again and I wanted to open the WebApp in my browser but I got the "Failed to load the Widgetset..." error message. I thought that I have to recompile the Widgetset but the vaadin-maven-plugin throws an error:

EDIT 04.05.2017: I removed the QueryDSL dependency "querydsl-apt" and the widgetset is compiling... Does anyone know why this happens?

Does anyone know whats going wrong?

Answer 1

That worked> Thanks a lot. I added :

 <exclusion>
    <groupId>org.eclipse.jdt.core.compiler</groupId>
    <artifactId>ecj</artifactId>
</exclusion>

in my pom dependency.

Answer 2

Generally NoSuchMethodError indicates a classpath problem, in the sense that the library that you have in your cp when writing the code (and your IDE is compiling inline your code to check it for errors) is a different version from the one in the maven compile-time cp. So a method that is available when writing the code is no longer found when compiling or running the code (see late binding).

In your particular case, this is most likely an indirect consequence due to the QueryDSL dependency that uses a JDT version, and the Vaadin maven plugin using a GWT plugin that references another JDT version.

As a workaround, you can explicitly exclude the JDT transitive dependency from either your QueryDSL version or the Vaadin maven plugin, and try to see if that works.

P.S. To see who exactly is referencing the JDT dependency you can run mvn dependency:tree
