Hi all,
i am currently developing a web application and i am now struggling with the same error for many days now.
What i did so far:
- I created an EMF project in eclipse (photon) with the project wizard. Just a basic data model with 8 classes and one or two relations each, just to other elements that are modeled here, no external types or anything else.
Everything works as expected and compiles just great without any problems.
- As the runtime platform i choose GWT as i want to use this project in my web application.
- The myProject.gwt.xml file is generated and looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 2.0.1//EN" "http://google-web-toolkit.googlecode.com/svn/tags/2.0.1/distro-source/core/src/gwt-module.dtd">
<!--
-->
<module>
<inherits name="com.google.gwt.user.User" />
<inherits name="org.eclipse.emf.ecore.Ecore" />
<source path=""/>
<source path="impl"/>
<source path="util"/>
</module>
- When i compile the EMF project with the GWT compiler (2.7 or 2.8) it works just fine, with any GWT SDK version.
- Now i inherit the created project in the xxx.gwt.xml file in my web application project with the following get.xml file and places the exported jar file of the EMF project under war/WEB-INF/lib.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 2.7.0//EN"
"http://gwtproject.org/doctype/2.7.0/gwt-module.dtd">
<module >
<inherits name='com.google.gwt.user.User'/>
<inherits name='com.google.gwt.user.theme.clean.Clean'/>
<inherits name='com.allen_sauer.gwt.dnd.gwt-dnd'/>
<inherits name="org.eclipse.emf.ecore.Ecore" />
<inherits name="x.y.MyProject" />
<entry-point class='x.y.webApplicationProject'/>
<source path='client'/>
<source path='shared'/>
</module>
- I also tried to include the project on the build path instead of the jar file, but the result is the same:

WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0x80000002. Windows RegCreateKeyEx(...) returned error code 5.

[ERROR] Errors in 'file:/C:/.../MyProjectPackageImpl.java'
[ERROR] Line 625: The method getResource(String) is undefined for the type Class<capture#1-of ? extends MyProjectPackageImpl>
[ERROR] Hint: Your source appears not to live underneath a subpackage called 'client'; no problem, but you'll need to use the <source> directive in your module to make it accessible
The last error just came up today. Unfortunately i cannot reproduce what i did before it came up. My source is underneath the client package and is also added as <source>.
Does anyone have an idea where that comes from? Creating a new Project and importing my code did not solve anything.
