Description

GWTTestCase require some complex setup, as tje GWT compiler requires acces to the java sources, and classpath scanning for available jars at runtime :

<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<additionalClasspathElements>
<additionalClasspathElement>src/main/java</additionalClasspathElement>
<additionalClasspathElement>src/test/java</additionalClasspathElement>
<additionalClasspathElement>target/generated-sources/gwt</additionalClasspathElement>
</additionalClasspathElements>
<useManifestOnlyJar>false</useManifestOnlyJar>
<systemProperties>
<property>
<name>gwt.args</name>
<value>-out target/www-test</value>
</property>
</systemProperties>
<argLine>-Xmx256M</argLine>
</configuration>
</plugin>

Even with this configuration, the test fails with a tomcat ClassCastException "GWTShellServlet is not a Servlet"

I may be wrong, but it seems the useManifestOnlyJar=false mode still uses the tmp file classpath elements to build it's classpath, and not the system classpath.
