Cannot get android-apt working

问题:

Twice already I've tried to get android-apt to work, because it's required by the 3rd-party libraries I wanted to use (AndroidAnnotations and PermissionsDispatcher), and both times I bashed my head against the wall until I got tired of hearing the squishing sound.

The problem? Android Studio simply fails to find or fetch the dependencies:

Error:Could not find com.neenbedankt.gradle:plugins:android-apt.
Searched in the following locations:
    file:/Applications/Android Studio.app/Contents/gradle/m2repository/com/neenbedankt/gradle/plugins/android-apt/plugins-android-apt.pom

I'm probably making some sort of ridiculous mistake (I mean, those libraries would not see any use otherwise, right?), but I can't see what I'm doing wrong.

I'm running Android Studio 1.4, in case it's somehow relevant.

This is the gradle file for the project:

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.0'
        classpath 'com.neenbedankt.gradle:plugins:android-apt:1.8'
    }
}

allprojects {
    repositories {
        jcenter()
        mavenCentral()
        mavenLocal()
    }
}

apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'

dependencies {
    compile 'com.github.hotchemi:permissionsdispatcher:1.2.1'
    apt 'com.github.hotchemi:permissionsdispatcher-processor:1.2.1'
}

This is the gradle file for the module I'm mostly working on:

apply plugin: 'com.android.application'

    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {

回答1:

I had the same problem. This helped me to figure it out.

On the app module itself, add these lines (order is important):

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
    }
}

apply plugin: 'com.android.application'
apply plugin: 'android-apt'


dependencies {
    compile 'com.github.hotchemi:permissionsdispatcher:1.2.1@aar'
    apt 'com.github.hotchemi:permissionsdispatcher-processor:1.2.1'
}

回答2:

As of the Android Gradle plugin version 2.2, all functionality that was previously provided by android-apt is now available in the Android plugin. This means that android-apt is officially obsolete ;)

Thus,

1. Make sure you've updated your Gradle plugin to be >= 2.2
2. Instead of apt use annotationProcessor

I figured this way on Android Studio 2.2.1:

This lets me use Butterknife on the main project and also on the library at the same time.

Please note that, on the library, use R2.id.blah instead of R.id.blah when using Butterknife annotations.

Hope works for all.

1) project gradle file:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.1'
        classpath 'com.jakewharton:butterknife-gradle-plugin:8.4.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

2) app graddle file

3) library graddle file
