Re: GWT tutorial does not compile

Do not use that old GWT Maven plugin... it makes no sense, it is too old and all of the new stuffs in GWT are using TBroyer GWT Maven plugin 😉

It's very good Maven plugin...

I was trying to follow the tutorial so I did not try your other sample yet.
I think the reason is, my employer uses Mojo GWT Maven from Codehaus.
Unless I am mistaken, it does not seem to have gwt-app packaging.

Hmm wyrd...

Did you try to download the zip (, unpack it and start in the unpack directory?

mvn gwt:generate-module gwt:devmode

or complete:

mvn net.ltgt.gwt.maven:gwt-maven-plugin:generate-module net.ltgt.gwt.maven:gwt-maven-plugin:devmode

today I won't use the GWT plugin for Eclipse anymore... 

I would just use Eclipse / IntelliJ / Visual Studio Code and Maven.

Some introductions:
Hope this helps.

I am learning GWT and was trying to run this tutorial

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.
