Android项目集成Google BigQuery遇mergeDebugJavaResource构建错误

问题背景 #

尝试在Java Android项目中集成Google BigQuery Java库，Gradle同步无异常，但构建项目时触发资源合并失败错误。已尝试清理项目、重置Gradle缓存，问题未解决。

当前环境：

• Gradle版本：7.4
• Android Studio版本：Dolphin | 2021.3.1 Patch 1

当前Gradle配置 #

plugins {
    id 'com.android.application'
}

android {
    namespace 'com.example.myapplication'
    compileSdk 32

    defaultConfig {
        applicationId "com.example.myapplication"
        minSdk 21
        targetSdk 32
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

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

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    packagingOptions {
        exclude 'META-INF/INDEX.LIST'
        exclude 'META-INF/DEPENDENCIES'
    }
}

configurations {
    cleanedAnnotations
    implementation.exclude group: 'com.google.auto.value', module: 'auto-value'
}

dependencies {
    implementation 'androidx.appcompat:appcompat:1.5.1'
    implementation 'com.google.android.material:material:1.7.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.1.4'
    testImplementation 'junit:junit:4.13.2'
    androidTestImplementation 'androidx.test.ext:junit:1.1.4'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.5.0'

    implementation platform('com.google.cloud:libraries-bom:26.1.4')
    implementation 'com.google.cloud:google-cloud-bigquery'
}

解决方案 #

问题根源是多个Apache Arrow依赖包包含同名的arrow-git.properties文件，导致Java资源合并时冲突。修改packagingOptions配置即可解决，以下两种方案二选一：

方案1：保留第一个找到的文件 #

在android块的packagingOptions中添加规则：

packagingOptions {
    exclude 'META-INF/INDEX.LIST'
    exclude 'META-INF/DEPENDENCIES'
    pickFirst 'arrow-git.properties'
}

方案2：直接排除该文件 #

在android块的packagingOptions中添加规则：

packagingOptions {
    exclude 'META-INF/INDEX.LIST'
    exclude 'META-INF/DEPENDENCIES'
    exclude 'arrow-git.properties'
}

修改后重新构建项目即可解决冲突问题。
