android - Roboblender annotation processing not working -

i try make roboblender work roboguice compile time processing doesn't seem anything, annotationdatabaseimpl class not generated. (project builds without error.)

i created sample project, please see below. miss? (i know gradle task , second metadata needed multi module project, didn't work without them either).

build.gradle:

project.tasks.withtype(javacompile) { task ->     options.compilerargs << "-aguiceannotationdatabasepackagename=gk.com.roboguice_compile" }  dependencies {     compile filetree(dir: 'libs', include: ['*.jar'])     compile 'com.android.support:appcompat-v7:22.0.0'     compile 'org.roboguice:roboguice:3.+'     provided 'org.roboguice:roboblender:3.+' } 

manifest:

    <meta-data         android:name="roboguice.modules"         android:value="gk.com.roboguice_compile.roboguicebindings" />      <meta-data         android:name="roboguice.annotations.packages"         android:value="gk.com.roboguice_compile" /> 

activity:

@contentview(r.layout.activity_main) public class mainactivity extends roboactivity {      @inject     private presentmaker presentmaker; 

bindings:

public class roboguicebindings extends abstractmodule {      @override     protected void configure() {         bind(presentmaker.class).to(birthdaypresentmaker.class);     } } 

the annotationdatabaseimpl there under build directory not among source files.

my bad, every annotation processor work this. (although strangely this project has annotationdatabaseimpl generated in project root..).
