I'm having trouble using this plugin with the simple demo application from gwtproject.org/gettingstarted

After creating the demo application using the webAppCreator and applying a gradle wrapper setup. I don't know how to apply this gradle plugin and rearrange the war/webapp-folder to make it work. The webAppCreator uses ant. So it needs to be altered to work with gradle.

Can someone please show me the simplest setup for the demo application created by the webAppCreator

./webAppCreator -out MyWebApp com.mycompany.mywebapp.MyWebApp

Here are many examples about how to use this plugin.

No ant needed, just use Gradle instead.

I have managed to make it work with the demo application. But only if I use jdk 8.

It stops working when I change sourceCompatibility and targetCompatibility to jdk 11.

I also tried this:

  java {
    toolchain {
        languageVersion = JavaLanguageVersion.of(11)
    }
  }

Did you see any errors? I will test with Java 11 when I have time.

Sorry for the terrible error report. I will try to make a better one when I'm back at work and my children don't interrupt me :)

The problem I have is that devmode (gwtDev) is not working when using java 11. The GWT Development Mode GUI starts. But when I click "Launch Default Browser" javascript is not compiled. I get this in the browser;

Error 503

HTTP ERROR: 503

Problem accessing /MyWebApp.html. Reason:

    Service Unavailable
* * *
_Powered by Jetty://_

It starts working again when I upgraded the jetty dependencies. But I'm not an expert at Gradle and don't know if I did it the right way. I added this in the MyWebApp/build.gradle

dependencies {
    gwt 'org.eclipse.jetty:apache-jsp:9.4.46.v20220331'
    gwt 'org.eclipse.jetty:jetty-annotations:9.4.46.v20220331'
    gwt 'org.eclipse.jetty:jetty-servlets:9.4.46.v20220331'
    gwt 'org.eclipse.jetty:jetty-webapp:9.4.46.v20220331'
}

When I try with a version >= 10.x it starts to complain about not finding a class. I think it just wants an implementation for slf4j but I did not managed to add logback to the dependencies so that the gwtDev task uses it.

[jiakuan]

GWT devmode has been replaced by Super Dev Mode, which works better for modern browsers.

https://www.gwtproject.org/articles/superdevmode.html

Yes, it may need some tweaks to make the dependencies right.

[martonsz]

Both jetty and cargo plugins seem a bit old.

Can you make an example using gretty?

[martonsz]

I managed to make it work with super dev mode using the follwing versions:

• jiakuan/get-gradle-plugin 1.1.18
• gwt 2.9.0
• JDK 11
• Gradle 7.4.2
• gretty 3.0.7

I created a repo for my sample project if someone is interested: https://github.com/martonsz/jiakuan-gwt-gradle-plugin-sample

Thanks for arranging the sample project. I will put it into the examples folder when I get a chance.
