在 Android Studio 中使用 AspectJ .aj 文件，编织似乎没有发生

Question

我是 AspectJ 的新手，我们正在努力将最初使用 Eclipse 编写的第三方应用程序迁移为使用 Android Studio 1.1.0 和 Gradle。我们已经获取了这个应用程序需要的外部库并在项目中创建了一个库模块，这个库有一个 AspectJ .aj 文件，我们需要编译它并与主应用程序一起工作字段级 Observable 模式。使用找到的插件 here，我已经能够将 .aj 文件编译成 .class文件，通过查看 intermediates 文件夹进行验证。

问题出现在 'weaving' 步骤，该代码应该被注入到必要的 classes 的字节码中。这似乎没有发生，因为应该在字段更改时通知的侦听器没有发生。以下是我的构建文件。

项目build.gradle:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.0'
        classpath 'com.uphyca.gradle:gradle-android-aspectj-plugin:0.9.12'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

应用模块build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 19
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.example.myapp"

        targetSdkVersion 19
    }

        release {
            minifyEnabled false

我错过了什么？

在 Android Studio 中使用 AspectJ .aj 文件，编织似乎没有发生
