添加 support:preference-v7 或 -v14 库会导致 Gradle 构建失败

Question

我的项目构建良好，直到我尝试包含支持首选项库。

当我这样做时，构建失败并出现此错误：

C:\Users\user\.gradle\caches\transforms-1\files-1.1\appcompat-v7-27.0.0.aar\e8afe3ff4b4dc10495266439a3695e57\res\values\values.xml:252:5-69: AAPT: error: duplicate value for resource 'attr/min' with config ''.

C:\Users\user\.gradle\caches\transforms-1\files-1.1\appcompat-v7-27.0.0.aar\e8afe3ff4b4dc10495266439a3695e57\res\values\values.xml:252:5-69: AAPT: error: resource previously defined here.

C:\Users\user\StudioProjects\project\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values\values.xml:627: error: duplicate value for resource 'attr/min' with config ''.

C:\Users\user\StudioProjects\project\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values\values.xml:483: error: resource previously defined here.

* What went wrong:
Execution failed for task ':app:mergeDebugResources'.
> Error: java.util.concurrent.ExecutionException: com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs for details

我真的不知道为什么会出现这个错误...

编辑：完整 build.gradle：

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

android {
    compileSdkVersion 27

    compileOptions { 
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    defaultConfig {
        applicationId "com.myapp"
        minSdkVersion 16
        targetSdkVersion 27
        multiDexEnabled true
        versionCode 1
        versionName "myVersion" 
        resConfigs "en"
    }

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

        debug {
            ext.enableCrashlytics = false
        }
    }
}

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

    def firebaseVersion = '11.4.2'
    def supportVersion = '27.0.0'

    //Firebase Crashlytics
    compile('com.crashlytics.sdk.android:crashlytics:2.7.1@aar') {
        transitive = true
    }

    //Firebase
    implementation 'com.google.firebase:firebase-auth:' + firebaseVersion
    implementation 'com.google.firebase:firebase-core:' + firebaseVersion
    implementation 'com.google.firebase:firebase-firestore:' + firebaseVersion

    //FirebaseUI
    implementation 'com.firebaseui:firebase-ui-auth:3.1.0'

    //Android Support
    implementation 'com.android.support:support-v4:' + supportVersion

    implementation 'com.android.support:appcompat-v7:' + supportVersion
    implementation 'com.android.support:cardview-v7:' + supportVersion
    implementation 'com.android.support:gridlayout-v7:' + supportVersion
    implementation 'com.android.support:recyclerview-v7:' + supportVersion
    implementation 'com.android.support:preference-v7:' + supportVersion

    implementation 'com.android.support:preference-v14:' + supportVersion 

    implementation 'com.android.support:support-vector-drawable:' + supportVersion

    implementation 'com.android.support:design:' + supportVersion

    implementation 'com.android.support.constraint:constraint-layout:1.0.2'

    implementation 'com.android.support:multidex:1.0.2'

    //Material About
    implementation 'com.github.daniel-stoneuk:material-about-library:2.2.3-support26.1.0' //Weird version system

    //OpenCSV
    implementation('com.opencsv:opencsv:4.0') {
        //Transitively requires Apache Commons, which necessitates multidex...
        exclude group: 'commons-beanutils'
    }

    //Gson
    implementation 'com.google.code.gson:gson:2.8.2'
}

apply plugin: 'com.google.gms.google-services'

它需要更多细节，所以我会详细说明这个问题。我想使用 AppCompat Preference 库，但每当我尝试将它添加到我的 build.gradle 时，开头的错误就会弹出。

Answer 1

您可以转到文件->使缓存无效/重新启动。这将使您项目中的任何错误都无效。如果有帮助，请告诉我！

Answer 2

您可以尝试从 Material 关于库中排除支持库：

  implementation ('com.github.daniel-stoneuk:material-about-library:2.2.3-support26.1.0') {
    exclude group: 'com.android.support'
    exclude module: 'appcompat-v7'
    exclude module: 'cardview-v7'
    exclude module: 'design'
  }

请看其build.gradle：https://github.com/daniel-stoneuk/material-about-library/blob/master/build.gradle

Answer 3

显然问题是由我的 attrs.xml:

中的一个 ID 引起的

<resources>
    <declare-styleable name="MyView">
        <attr name="min" format="float" />
    </declare-styleable>
</resources>

我通过将 min 更改为 minValue 来修复此错误。
