I can "fix" the problem with this extra plugin dependencies ... but I'm not sure if this is the right way.

<dependencies>
          <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
            <version>4.0.1</version>
            <scope>runtime</scope>
          </dependency>
        </dependencies>

Thx for reporting. I'll take a look at this - I thought we actually did include the transitive dependencies. It should not harm anything adding the servlet spec classes as you have done.

I had to do the same, using Version 2.1.6.
