已存在的程序类型: com.google.common.annotations.GwtCompatible

Question

在构建我的android项目时，我得到了以下错误：

程序类型已经出现: com.google.common.annotations.GwtCompatible消息{kind=ERROR，text=Program类型已经出现: com.google.common.annotations.GwtCompatible，sources=Unknown源文件，工具name=Optional.of(D8)}

分级文件：

 apply plugin: 'com.android.application'

    android {
        compileSdkVersion 27
        defaultConfig {
            applicationId "com.example.www.www"
            minSdkVersion 15
            targetSdkVersion 27
            versionCode 1
            versionName "1.0"

            // multi-dex support (When your app and the libraries it references exceed 65,536 methods)
            multiDexEnabled true
        }
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }
        packagingOptions {
            exclude 'META-INF/DEPENDENCIES'
            exclude 'META-INF/LICENSE'
            exclude 'META-INF/LICENSE.txt'

            exclude 'META-INF/NOTICE.txt'
            exclude 'META-INF/notice.txt'
            exclude 'META-INF/ASL2.0'
            exclude 'META-INF/INDEX.LIST'
        }
    }

    dependencies {
        // multi-dex support (When your app and the libraries it references exceed 65,536 methods)
        implementation 'com.android.support:multidex:1.0.3'


        implementation fileTree(dir: 'libs', include: ['*.jar'])
        implementation 'com.android.support:appcompat-v7:27.1.1'
        implementation 'com.android.support.constraint:constraint-layout:1.1.0'
        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'


        //this is for the google "text recognizer"
        implementation 'com.google.android.gms:play-services-vision:15.0.2'
        implementation 'com.google.apis:google-api-services-customsearch:v1-rev63-1.23.0'


        //for firebase database connection
        implementation 'com.google.firebase:firebase-database:16.0.1'
        //implementation 'com.google.firebase:firebase-core:16.0.0'
        // for firebase authentication
        implementation 'com.google.firebase:firebase-auth:16.0.1'
        implementation 'com.google.android.gms:play-services-auth:15.0.1'


        // for Google Natural Language Processing (part of google cloud services)
        implementation ('com.google.cloud:google-cloud-language:1.31.0')
              //  {
              //      exclude group: 'com.google.guava'
              //  }

    }


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

以下是解决这一问题的办法：

implementation ('com.google.cloud:google-cloud-language:1.31.0') { 
    exclude group: 'com.google.guava'
}

但是，我缺少了番石榴函数，因为运行时将引发以下错误：

没有找到"com.google.common.base.MoreObjects“类 原因: java.lang.NoClassDefFoundError:失败的解决方案:Lcom/google/ Failed /base/MoreObjects；

运行以下代码时: public void testSomething(视图视图){

    // Instantiate the Language client com.google.cloud.language.v1.LanguageServiceClient
        try {
            InputStream inputStream = getAssets().open("www.json");

            GoogleCredentials googleCredential = GoogleCredentials.fromStream(inputStream);
    }
    catch (Exception e){
        Log.e(TAG,e.getMessage());
        e.printStackTrace();
    }

我在这里绕圈。我很想找到答案。我检查了其他的问题/题目，没有对我有帮助的答案。

Answer 1

我通过以下修改解决了同样的问题：

implementation ('com.google.apis:google-api-services-drive:v2-rev105-1.17.0-rc'){
    exclude module: 'guava-jdk5'
}
implementation ('com.google.api-client:google-api-client-android:1.20.0'){
    exclude module: 'guava-jdk5'
}

Answer 2

将Gradles改为：

implementation 'com.google.apis:google-api-services-vision:v1-rev369-1.23.0'  exclude module: 'guava-jdk5'
    implementation 'com.google.api-client:google-api-client-android:1.23.0' exclude module: 'guava-jdk5' exclude module: 'httpclient'
    implementation 'com.google.http-client:google-http-client-gson:1.23.0' exclude module: 'httpclient'

​

这对我来说很管用
