Error when defining custom ApplicationSpec

Help/Discuss
#1

Hi,

I’m playing around with the software model

@Managed
interface TheApp extends ApplicationSpec {}
@Managed
interface TheAppBinary extends ApplicationBinarySpec {}

class MyRules extends RuleSource{
        @ComponentBinaries
	void appBinaries(ModelMap<TheAppBinary> binaries, TheApp app) {
		binaries.create(app.name) {}
	}
}

apply plugin : MyRules

model {
    components {
        main(TheApp) {}
    }
}

I get following error

> Exception thrown while executing model rule: MyRules#appBinaries > create(main)
   > Cannot create a 'org.gradle.platform.base.ApplicationSpec' because this type is not known to components. Known types are: (None)

if I change from ApplicationBinarySpec to just BinarySpec it works. Maybe I got it wrong but I thought when I define a custom ApplicationSpec the binary part should be of ApplicationBinarySpec.

Done with 2.11-rc-1

In 2.11 you need to register both the component type (TheApp) and binary type (TheAppBinary). You do this using methods on the RuleSource. Take a look at the customModel/componentType sample in the Gradle distribution for an example of how to do this.

Ok I overlooked that, but after adding I get a similar error

@Managed
interface TheApp extends ApplicationSpec {}
@Managed
interface TheAppBinary extends ApplicationBinarySpec {}

class MyRules extends RuleSource{

	@ComponentType
	void register(ComponentTypeBuilder<TheApp> builder) {}
	@BinaryType
	void register(BinaryTypeBuilder<TheAppBinary> builder) {}
		
	@ComponentBinaries
	void appBinaries(ModelMap<TheAppBinary> binaries, TheApp app) {
		binaries.create(app.name) {}

	}
}

apply plugin : MyRules

model {
    components {
        main(TheApp) {}
    }
}

Exception thrown while executing model rule: MyRules#appBinaries > create(main)
Cannot create a ‘org.gradle.platform.base.ApplicationSpec’ because this type is not known to components. Known types are: TheApp

Ok, this looks like a bug. As a workaround, you can have TheAppBinary extend BinarySpec instead of ApplicationBinarySpec.

ok thanks, should I create an issue for that?
