GWT tutorial does not compile

I am learning GWT and was trying to run this tutorial http://www.gwtproject.org/doc/latest/tutorial/index.html

Using the Eclipse GWT plugin 3.0 on Windows 10 and JDK 11

I get this error on the first line Error: There is '1' error in 'gwt-module.dtd'.

I installed the plugin from the marketplace.

I see this error in other tutorials too.

Any suggestions appreciated.
