GWT test case: no compilation unit for that type was seen ... why?

Question

I'm using GWT 2.4. I having trouble running some GWTTestCase files that I recently created in a new package. I have files correctly running in an existing package and I can't figure out why tests like the below are failing. I'm using Maven 3.0.3 to launch these. Here is how I have my plugin configured ...

        <!-- GWT Maven Plugin -->
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>gwt-maven-plugin</artifactId>
            <version>${gwtVersion}</version>
            <executions>
                <execution>
                    <id>clean-compile</id>
                    <goals>
                        <goal>clean</goal>
                        <goal>compile</goal>
                    </goals>
                </execution>
                <execution>
                    <id>run-gwt-tests</id>
                    <phase>test</phase>
                    <goals>
                        <goal>test</goal>
                    </goals>
                </execution>
            </executions>
            <!-- Plugin configuration. There are many available options, see gwt-maven-plugin 
                documentation at codehaus.org -->
            <configuration>
                <runTarget>index.html</runTarget>
                <hostedWebapp>${webappDirectory}</hostedWebapp>
                <i18nMessagesBundle>com.myco.clearing.product.client.Messages</i18nMessagesBundle>
            </configuration>
        </plugin>

Here is the test main part of the test file ...

package com.myco.product.client.view;
...
public class GwtTestAppView extends GWTTestCase {

private AppView appView;

@Override
public String getModuleName() {
    return "com.myco.clearing.product.ProductPlusJUnit";
}   // getModuleName

public void gwtSetUp() {
    appView = new AppView();
    RootPanel.get().add(appView);
} // gwtSetup

public void testShowLoading() { 
    testShowLoading(true);
}   // testShowLoading

and here is the error I get when I run "mvn clean test"

As I said, I'm able to run gwt tests fine that are located in a different package (named com.myco.product.client.xmltohtml), so I can't figure out what's different. What is the problem?

Answer 1

Oops, my test class wasn't in a package recognized by the module I was loading. The package should have been "com.myco.clearing.product.client.view". Changing the package fixed everything.
