Trying to communicate with LibGDX project per Javascript with JsInterop. I am following the "Exporting a Java type to JavaScript" example here. It does not work: Uncaught ReferenceError 'com' is not defined. I am not getting any errors with gradle though.
I have already:
- checked that generateJsInteropExports is enabled:
My GdxDefinition.gwt.xml:
<module rename-to="html">
<inherits name='com.badlogic.gdx.backends.gdx_backends_gwt' />
<inherits name='com.badlogic.gdx.physics.box2d.box2d-gwt' />
<inherits name='myapp' />
<entry-point class='com.mypackage.myapp.client.HtmlLauncher' />
<set-configuration-property name="gdx.assetpath" value="../android/assets" />
<set-configuration-property name='xsiframe.failIfScriptTag' value='FALSE'/>
<set-configuration-property name='generateJsInteropExports' value='true'/>
<set-property name="user.agent" value="safari"/>
</module>
I was thinking, maybe the entry point HtmlLauncher should be also a @JsType, but this did not work either.
Also checked that generateJsInteropExports is enabled in
GdxDefinitionSuperdev.gwt.xmlAccessing the class in the browser console in different ways like:
.
new com.mypackage.myapp.client.Test();
new Test(); // when setting namespace to global
$wnd.Test(); // JSNI syntax
I am compiling like that:
gradlew.bat html:dist --daemon -generateJsInteropExports=true
My class (Right in the html module, also tried in core module, still does not work) looks like that:
package com.mypackage.myapp.client;
import jsinterop.annotations.JsPackage;
import jsinterop.annotations.JsType;
@JsType(namespace = JsPackage.GLOBAL)
public class Test {
public String name;
public Test(String name) {
this.name = name;
}
public void sayHello() {
return "Hello" + this.name;
}
}
I am running out of ideas. Can somenody help me figuring out what to do so that it works.
Some information that might be useful:
Code from my html.gradle:
gwt {
gwtVersion='2.8.0' // Should match the gwt version used for building the gwt backend
//...
modules 'com.mypackage.myapp.GdxDefinition'
devModules 'com.mypackage.myapp.GdxDefinitionSuperdev'
project.webAppDirName = 'webapp'
compiler {
strict = true;
disableCastChecking = true;
}
}
import org.wisepersist.gradle.plugins.gwt.GwtSuperDev
//...
task superDev (type: GwtSuperDev) {
dependsOn startHttpServer
doFirst {
gwt.modules = gwt.devModules
}
}
//...
Code from my project gradle
buildscript {
//...
dependencies {
classpath 'org.wisepersist:gwt-gradle-plugin:1.0.6'
//...
}
}
project(":html") {
apply plugin: "gwt"
apply plugin: "war"
dependencies {
compile project(":core")
compile "com.badlogicgames.gdx:gdx-backend-gwt:$gdxVersion"
compile "com.badlogicgames.gdx:gdx:$gdxVersion:sources"
compile "com.badlogicgames.gdx:gdx-backend-gwt:$gdxVersion:sources"
compile "com.badlogicgames.gdx:gdx-box2d:$gdxVersion:sources"
compile "com.badlogicgames.gdx:gdx-box2d-gwt:$gdxVersion:sources"
compile "com.google.jsinterop:jsinterop-annotations:1.0.1"
}
}
project(":core") {
apply plugin: "java"
dependencies {
//...
compile "com.google.jsinterop:jsinterop-annotations:1.0.1"
}
}
//...
UPDATE 1
I checked Colin Alworth's answer and the links he posted. It still does not work. I changed:
html.gradle
gwt {
gwtVersion='2.8.0' // Should match the gwt version used for building the gwt backend
maxHeapSize="1G" // Default 256m is not enough for gwt compiler. GWT is HUNGRY
minHeapSize="1G"
src = files(file("src/")) // Needs to be in front of "modules" below.
modules 'com.mycompany.myapp.GdxDefinition'
devModules 'com.mycompany.myapp.GdxDefinitionSuperdev'
project.webAppDirName = 'webapp'
compiler {
strict = true;
disableCastChecking = true;
}
jsInteropExports {
shouldGenerate = true
includePatterns = ['com.mycompany.myapp.client.*']
}
}
Like it says here.
I call like: gradlew.bat html:dist --daemon and I removed the property generateJsInteropExports from GdxDefinition files since it seems wrong.
Now I get following compilation error:
Task :html:compileGwt FAILED
Unknown argument: -includeJsInteropExports
Why is that?
