I have been using Ubuntu for some time and it is really a great OS, but it is amazing why it is always Eclipse that brings the most headache when upgrading Ubuntu. For a couple a days ago I upgraded to Ubuntu 10.04, and everything works smoothly until I started Eclipse 3.5 SR1, with bug fixes I have previously described.

This time the solution was to upgrade to Eclipse 3.5 SR 2 (Galileo), without the above bug fix. But thereafter m2eclipse gave me some problem, but now it seams to work after reinstalling m2eclipse and following the guideline in
http://m2eclipse.sonatype.org/installing-m2eclipse.html
“Note about 0.9.8 Workspace Incompatibility: If you are using m2eclipse 0.10.0 with a workspace that contains projects created under m2eclipse 0.9.8, you must remove the workspaceState.ser file. The workspaceState.ser file is located within the workspace directory in $workspacedir/.metadata/.plugins/org.maven.ide.eclipse/workspaceState.ser. If you remove this file, m2eclipse 0.10.0 will regenerate it as needed.”

Getting Starting with Google Web Toolkit, GWT, Development
To get started first install appropriate plug-in for your IDE, in this article we will use Eclipse, but there are other great plug-in for other IDE as well.
Eclipse GWT plugin
http://code.google.com/eclipse/docs/download.html
One of the biggest difference between GWT 1.* and 2.* is the ability to debug and run your GWT application without the need to render/compile it. Now you can directly run/debug your GWT Java code without the time consuming compile step. But to do this you first need to install a plug-in to your web browser.
GWT Development Mode plugin for Firefox, IE and Safari

After restarting Eclipse and your Web browser you are now ready to start developing. Begin with creating a new project and select Google → Web Application Project.
Enter project details. In this article we will not create a Google App Engine Application, which is a platform for writing cloud application for the Google cloud platform. To read more about Google App Engine, visit http://code.google.com/appengine/.
After finishing creating your project. Lets fire it up and start debug the complete GWT project. The GWT team has already configured a default debug goal. So simple press the debug icon in the Eclipse toolbar.
Now is a URL presented in the Eclipse Console output View. Right click on that URL and select Copy. Paste the URL in your web browser.
Now lets set a breakpoint in your application and the enter a name in your browser and click submit. And now you are debugging your first GWT application.
