android - 将 butterknife 添加到 android 库项目会为库类提供编译时错误 "package does not exists"

Question

我试图将 butterknife 库添加到我的库项目中并按照步骤操作。

https://github.com/JakeWharton/butterknife. 

项目在 gradle sync 时没有显示任何错误，但是当我尝试运行应用程序时，它返回编译错误 package does not exits for my library classes that I have used in the application.

error

error:package com.sample.library.BaseMainActivity does not exist
error:cannot find symbol class BaseMainActivity
error:cannot find symbol variable super

// Top-level build file where you can add configuration options common to all sub-projects/modules.

        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
    }

apply plugin: 'com.android.library'

apply plugin: 'com.jakewharton.butterknife'


android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {

    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.4.0'
    compile 'com.android.support:design:23.4.0'
    compile 'com.android.support:cardview-v7:23.4.0'
    compile 'com.android.support:recyclerview-v7:23.4.0'

    //Dagger
    apt 'com.google.dagger:dagger-compiler:2.2'
    compile 'com.google.dagger:dagger:2.2'
    provided 'javax.annotation:jsr250-api:1.0'

    // ButterKnife
    compile 'com.jakewharton:butterknife:8.4.0'
    apt 'com.jakewharton:butterknife-compiler:8.4.0'
}

如果我删除 ButterKnife 依赖项，应用程序将无错误地运行。图书馆项目以某种方式与 butterknife 图书馆发生冲突，但无法找出原因和方式。请帮助我做错了什么。

如果升级 library 中的 Dagger 版本，一切编译都没有问题。

使用:

apt 'com.google.dagger:dagger-compiler:2.4'
compile 'com.google.dagger:dagger:2.4'
