GWT compilation problem The constructor StackTraceElement(String, String, String, int) is undefined

问题

I am compiling my GWT module in Eclipse that inherits my other module (that compiles without problems) and I get this output:

Compiling module mymodule.GWT_TESTS

My module definition is:

<module>
    <inherits name='com.google.gwt.user.User'/>
    <inherits name="com.google.gwt.i18n.I18N"/>
    <inherits name='othermodule.Main' />

    <entry-point class='mymodule.client.GWT_TESTS'/>
</module>

How to resolve this kind of compilation problem? Am I forgetting inheriting from other modules (I tried to add the those where classes were not resolved even they should be inherited via User module and it did not help)? Is there anything in my Eclipse project setting that I am missing (mymodule is in a separate project, GWT configured, gwt 2.0.4, other modules and JARs are set in project dependencies)?

回答1:

I deleted the project and recreated it again and it works now. I originally used GWT that came with Eclipse plugin (2.3.0) but then I had to change GWT version to 2.0.4. Either changing the GWT version for existing project or another of my change when I was resolving the problem caused the error.
