Error deploying gwt project with Eclipse/Maven


I started to use Maven in Eclipse (m2eclipse) recently. Unfortunately lately I've been unable to run the application from Eclipse. I get the error:

Loading modules src.main.java.com.ohapp.webconfuturo.WebConfuturo Loading inherited module 'src.main.java.com.ohapp.webconfuturo.WebConfuturo' [ERROR] Unable to find 'src/main/java/com/ohapp/webconfuturo/WebConfuturo.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source? [ERROR] shell failed in doStartup method

I already checked and the file is there. Isn't visible in Eclipse but is in the file system.

Strangely if I run the program through Maven (mvn gwt:run) it works just fine.

My pom.xml (without the dependencies) is the following:

<!-- Dependecies --!>

        <!-- Generate compiled stuff in the folder used for development mode -->

What am I doing wrong?

Thanks


Solution

  • I figured this one out. The arguments in my Run settings where wrong. I had the the gwt.xml file referenced with full path and not relative to source folder:

    src.main.java.com.ohapp.appname.AppName
    

    I changed it to:

    com.ohapp.appname.AppName
    

    And problem solved.

    I don't know how this happened since it wasn't me who made the changes.
