gradle - Android：为什么看不到子模块中的类？

Question

安卓工作室 3.2.1

我的主应用程序有模块“ binding”在目录中的这个模块中有jar /libs/androidbinding.jar：（gueei.binding.*）

好的。模块“ binding”成功构建。

现在在app/build.gradle 的主应用程序中：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.myproject"
        minSdkVersion 23
        targetSdkVersion 28
        versionCode 1
        versionName "1.1.1"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
    }
}

// must be version 4.5.2
def AAVersion = '4.5.2'

dependencies {
    annotationProcessor "org.androidannotations:androidannotations:$AAVersion"
    annotationProcessor "org.androidannotations:ormlite:$AAVersion"

    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:animated-vector-drawable:28.0.0'
    implementation 'com.android.support:exifinterface:28.0.0'
    implementation 'com.android.support:cardview-v7:28.0.0'
    implementation 'com.android.support:customtabs:28.0.0'
    implementation 'com.android.support:support-media-compat:28.0.0'
    implementation 'com.android.support:support-v4:28.0.0'

    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'org.apache.commons:commons-lang3:3.8.1'
    implementation 'org.apache.httpcomponents:httpclient:4.5.6'
    implementation 'com.google.android.gms:play-services-gcm:16.0.0'
    implementation 'com.google.code.gson:gson:2.8.2'
    implementation 'com.j256.ormlite:ormlite-android:5.1'
    implementation 'commons-io:commons-io:2.6'
    implementation "org.androidannotations:androidannotations-api:$AAVersion"
    implementation "org.androidannotations:ormlite-api:$AAVersion"

    implementation project(':binding')

}

如您所见，我使用：

 implementation project(':binding')

但是当我尝试构建主要的“ app ”项目时，我得到了错误：

import gueei.binding.Binder.InflateResult;
import gueei.binding.observables.StringObservable;

error: package gueei.binding.Binder does not exist

但 lib androidbinding.jar包含类“ gueei.binding.Binder.InflateResult”。

为什么主“应用程序”看不到模块“绑定”？

附言

如果我复制androidbinding.jar到app/libs/，则会收到另一个错误：

AGPBI: {"kind":"error","text":"Program type already present: gueei.binding.AttributeBinder$RefViewAttributeProvider","sources":[{}],"tool":"D8"}
:app:transformDexArchiveWithExternalLibsDexMergerForDebug FAILED
:app:buildInfoGeneratorDebug
