missing FactoryModuleBuilder runtime error with plugin

[Erez Lirov]

Hi!

I'm trying to add Gin to our GWT project.  I added the following to our .gwt.XML file:

    <inherits name='com.google.gwt.inject.Inject'/>

  <define-configuration-property name="gin.ginjector" is-multi-valued="false" />

    <set-configuration-property name="gin.ginjector"

       value="com.espoc.vericle.gwt.common.client.VericleGinjector" />

And we're trying to make a VericleGinjector like this in our module class:

@Override

  public void onModuleLoad() {

    VericleGinjector INSTANCE = GWT.create(VericleGinjector.class);

 //this is the entire function for testing purposes

  }

VericleGinjector.java looks like this:

@GinModules({ VericleGinModule.class })

public interface VericleGinjector extends Ginjector {

}

and VericleGinModule:

public class VericleGinModule extends AbstractGinModule {

  @Override

  protected void configure() {

  }

} 

Everything compiles fine on the command line, except some build warnings with GwtP that we're not actually using yet...

build:

But, we get the following error trying to load the module in eclipse through the plugin:

I feel like we're missing something fairly small here, but we don't have much experience with either Guice or Gin.  Any clues?

Thanks!!

I'm trying to add Gin to our GWT project.  I added the following to our .gwt.XML file:

    <inherits name='com.google.gwt.inject.Inject'/>

  <define-configuration-property name="gin.ginjector" is-multi-valued="false" />

    <set-configuration-property name="gin.ginjector"

       value="com.espoc.vericle.gwt.common.client.VericleGinjector" />

Not sure why you do this? Do you have a custom generator that reads that gin.ginjector property value or have you done that to make Gin work? If its the latter then a config property is used to reference GinModules and not Ginjectors. So it would look like:

<define-configuration-property name="gin.modules" is-multi-valued="false" />

<extend-configuration-property name="gin.modules" value="com.espoc.vericle.gwt.common.client.VericleGinModule" />

You can use the <extend-configuration-property> line multiple times to add multiple modules to your property. For example you could have a Core.gwt.xml that defines the property and then other <anyname>.gwt.xml GWT modules could add their GinModule to that config property.

Finally you use it like

@GinModules(value = {}, properties = {"gin.modules"})

interface VericleGinjector extends Ginjector {

....

}

But if you don't need that property at all you can simply remove it and just reference the module by class

@GinModules({ VericleModule.class })

interface VericleGinjector extends Ginjector {

....

}

So @GinModules can take a list of classes (through value = { MyModule.class, ...} ) and/or a list of config properties (through properties = { 'prop1', .. })

 

Everything compiles fine on the command line, except some build warnings with GwtP that we're not actually using yet...

Annotation processors can be discovered automatically by javac if a jar contains a special file in its META-INF/services directory. Thats probably the case for gwt-platform and as you use Java7 but the annotation processor requests Java6 you get the warning just because you have gwt-platform on classpath and its annotation processors are executed automatically.

But, we get the following error trying to load the module in eclipse through the plugin:

...

Caused by: java.lang.NoClassDefFoundError: com/google/inject/assistedinject/FactoryModuleBuilder

Do you have all GIN dependencies (gin, guice, guice-assistedinject, aopalliance and javax.inject jars) on classpath during compilation/DevMode?

That was it.  My dev mode didn't have all the jar files in it, so compilation worked, but dev mode didn't.

Also, the jars have to be in a certain order apparently.  This link helped a lot.
