Re: NoClassDefFoundError (HttpSessionIdListener) when launching SDM, after switching from gwt-2.8.0-beta1 to rc2

Or maybe adjust the classpathScope to include provided dependencies? http://tbroyer.github.io/gwt-maven-plugin/devmode-mojo.html#classpathScope / http://tbroyer.github.io/gwt-maven-plugin/codeserver-mojo.html#classpathScope

(see also the samples from the GWT SDK, or the POM generated by webAppCreator)

For anyone with the same issue as me, I had to remove the <scope>provided</scope> in the dependency management for javax.servlet

I'm having the same issue as Boris, except my dependency tree shows that I'm using 3.1:

The only place this is specified is in the parent pom:

    <dependencyManagement>

        <dependencies>

            <dependency>

                <groupId>com.google.gwt</groupId>

                <artifactId>gwt</artifactId>

                <version>2.8.0-rc2</version>

                <type>pom</type>

                <scope>import</scope>

            </dependency>

            <dependency>

                <groupId>javax.servlet</groupId>

                <artifactId>javax.servlet-api</artifactId>

                <version>3.1.0</version>

                <scope>provided</scope>

            </dependency>

        </dependencies>

    </dependencyManagement>

I get the exact same error that he posted when trying to run the codeserver. The only difference is that he's using gwt-maven-plugin:1.0-rc-4 and I'm using gwt-maven-plugin:1.0-rc-6
