设置注释处理器会导致 META-INF/DEPENDENCIES 出现问题

Question

我正在尝试处理这个错误（我在 Android Studio 中更新某些内容之前从未遇到过）：

Annotation processors must be explicitly declared now. The following dependencies on the compile classpath are found to contain annotation processor. Please add them to the annotationProcessor configuration. - auto-value-1.4.jar (com.google.auto.value:auto-value:1.4) Alternatively, set android.defaultConfig.javaCompileOptions.annotationProcessorOptions.includeCompileClasspath = true to continue with previous behavior. Note that this option is deprecated and will be removed in the future. See https://developer.android.com/r/tools/annotation-processor-error-message.html for more details.

所以我添加了一个注释处理器：annotationProcessor 'com.google.auto.value:auto-value:1.4'。

现在，显示了一个新错误：

More than one file was found with OS independent path 'META-INF/DEPENDENCIES'

问题

我读到我应该更改包装选项（ + Error : More than one file was found with OS independent path 'META-INF/LICENSE' + 等）。

但是，有没有一种方法可以在不触发第二个问题的情况下解决第一个问题，而只需对我的应用程序进行一些更改 build.gradle？会更好

build.gradle（应用级别）

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.example.x.x"
        minSdkVersion 26
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        renderscriptTargetApi 26
        renderscriptSupportModeEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.google.firebase:firebase-admin:6.5.0'
    implementation 'com.android.support:cardview-v7:27.1.1'
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:support-v4:27.1.1'
    implementation 'com.android.support:design:27.1.1'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

    implementation 'com.github.mancj:MaterialSearchBar:0.7.6'

    annotationProcessor 'com.google.auto.value:auto-value:1.4'
}

Answer 1

您可以完全排除文件或将其限制为出现一次：

android {

    ...
    packagingOptions {
        // pickFirst "META-INF/DEPENDENCIES"
        exclude "META-INF/DEPENDENCIES"
    }
}
