But I don't encounter this error when I build on command line, like ./gradlew assembleDebug.

You can reproduce error : https://github.com/sakuna63/Sandbox-Android/tree/groovy

Try removing skipJavaC since you need javaC to run in order to have annotation processors run.

Thanks for your reply!!

I've already tried it. but I encountered same error, without skipJavaC.

What does the reference have to do with anything?

Please change

androidGroovy {
    skipJavaC = true
    options {
        configure(groovyOptions) {
            javaAnnotationProcessing = true
        }
    }
}

to

androidGroovy {
    options {
        configure(groovyOptions) {
            javaAnnotationProcessing = true
        }
    }
}

If this additionally causes issues please include those here.

Adding a failing databinding test similar to the ones found here https://github.com/groovy/groovy-android-gradle-plugin/tree/05457107cf6e7c310a1c1a24f82b83c9fbbd0d2c/groovy-android-gradle-plugin/src/test/groovy/groovyx/functional I'd be able to more quickly support you.

Also, you are not using groovy in your application so I am unsure why you are including this plugin.

@sakuna63 can you provide an update?
