Re: GWT tutorial does not compile

Forget something...

It's wise to separate the "client" and the "server" in two Maven projects. Don't use the example of the Mojo Maven plugin because it mixes the client and server on the same Maven project.

I've once used it mixed (see https://github.com/interseroh/demo-gwt-springboot) but at the end I had a lot of troubles with the classpath. 

Here is an example how you could separate the client and server. At the end your result on the client is JavaScript and you can copy the result to the server part using maven-dependency-plugin: https://github.com/gwtboot/domino-rest-enum-date

Hope this helps.

... and yes, you can follow the tutorial with the TBroyer Maven plugin or the Mojo Maven plugin.

The code is the same, only the structure is different... You can compare both:

• TBroyer Maven plugin (up-to-date): https://github.com/lofidewanto/gwt-boot-sample-basic
• Mojo Maven plugin (deprecated): https://github.com/lofidewanto/gwt-old-maven-sample-basic

I checked the old Maven GWT Plugin... ok it still works for GWT 2.9 but I won't use it anymore. 

If you have to use it here is an example - just the same demo from my example above but use the old Maven plugin: https://github.com/lofidewanto/gwt-old-maven-sample-basic

The Java code is the same but it uses the structure of the old GWT Maven plugin... just take a look at the README of the project above.

Hope this helps.

Mojo GWT Maven plugin packages as war.

if I package as war, can I still follow the tutorial?

The GWT Java code like in the tutorial doesn't change at all, only the project structure with TBroyer GWT Maven plugin...

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.

https://gwt-maven-plugin.github.io/gwt-maven-plugin/ 

Unless I am mistaken, it does not seem to have gwt-app packaging.

Hmm wyrd...

Did you try to download the zip (https://github.com/lofidewanto/gwt-boot-sample-basic/archive/refs/heads/main.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

I get error:

Unknown packaging: gwt-app

Hi,

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

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

Some introductions:

• Here is a Padlet for GWT. You can find some presentations and articles about GWT here in this Padlet: https://bit.ly/GWTIntroPadlet 
• Introduction slides: https://bit.ly/gwtintropresentation
• Simple article: https://bit.ly/WebJavaStory
• Comprehensive article: https://dev.to/ibaca/modern-gwt-first-steps-509k 
• Simple "Hello World" example: https://github.com/lofidewanto/gwt-boot-sample-basic
  • Just download the code as a zip file or make a git clone
  • From this basic project you could do the tutorial steps above

Hope this helps.

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.
