Question

I am building a GWT project, and I am having problems with executing my GwtTest*.java unit tests. I can run the project in developer mode (mvn gwt:run). However when I go to run the unit tests using ‘mvn integration-test’ or ‘mvn gwt:test’ I receive the following error.

Loading inherited module 'com.mycompany.site.client.myproject'
   [ERROR] Unable to find 'com/mycompnay/site/client/myproject.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?

Below is my pom.xml

I am using the default project structure that is generated by maven when creating a GWT project using the GWT Maven Archetype. So my myproject.gwt.xml is located in src/main/resources/com/mycompany/site/myproject.gwt.xml. Any help on this problem would be greatly appreciated.

Answer 1

I figured out my problem. I miss-understood what was suppose to be returned from

public String getModuleName() { . . . }

I was originally returning the path to my entry point class, but you are suppose to return the path to your gwt.xml file. I miss-understood what ‘module’ was referring too.
