packages, like RangeTest. The reason for this is that GWT doesn't distinguish between
            .java files in c.g.c.collect.Collect, a module that the c.g.c.base test module inherits,
            and .java files in c.g.c.collect.testModule, one that it doesn't[*]. Consequently,
            c.g.c.base.testModule transitively pulls in .java files from both modules while reading

          <models />
        </configuration>
        <executions>
          <execution>
            <!-- This step is required to generate xdoc, and does not generate java code -->
            <id>modello-site-doc</id>
            <goals>
              <goal>xdoc</goal>
            </goals>
            <phase>pre-site</phase>
            <configuration>

            obvious way to ensure that.

            We could consider arranging things so that only the tests we know need this would get
            the add-opens. Right now that doesn't seem worth the effort, though.
