@Ed: Don't get me wrong. I like Eclipse and I am basically an Eclipse-only developer. I would use it to brew coffee if there was a plug in. :D
What I'm just missing are some basic support e.g. if I use GWTP I want to see some generated code. Java/GWT has some boilerplate code that could be generated.
Another thing that annoys me is that @UiField thing. Sometimes it's really annoying to keep all the field names up-to-date. Renaming stuff is sometimes a but nasty.
Then there's the thing with the code server.. I'd really appreciate a better view for the error messages that one gets there. You always have to search for the actual line that points out what's wrong instead of seeing that message in the Eclipse "Markers" view or something.
One more thing that I miss is a better Project Explorer. The files are sorted by type and that means you get A.java B.java A.ui.xml B.ui.xml instead of A.java A.ui.xml B.java B.ui.xml.
Since I am using gwt-maven-archetypes I even have to kill the Code Server by hand - I cannot use the Eclipse "Debug" or "Server" view for that.
Maybe some of that stuff could be avoided or changed but it's not supported out of the box by Eclipse afaik.
@Gilberto: Yes, that's actually a good point. The plugins can be sometimes a bit messy.
@Rogelio: What kind of support are we talking here? It happens that I might have access to the Ultimate edition for free as a student.
