启用proguard后调试应用构建失败

Question

Error:Execution failed for task 
':app:transformClassesWithAndroidGradleClassShrinkerForDebug'. 
Warnings found during shrinking, please use -dontwarn or -ignorewarnings to suppress them.

我该如何解决这个问题？

另外，我还想在我的应用程序中使用progaurd。

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion '26.0.2'

    dexOptions{
        javaMaxHeapSize="2g"
    }

    defaultConfig {
        applicationId "com.example.projetinnovation.newadvocatediary"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        multiDexEnabled=true

    }
    buildTypes {
        debug {
            minifyEnabled true
            useProguard false
            proguardFiles getDefaultProguardFile('proguard-andr    oid.txt'),
                    'proguard-rules.pro'
        }
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.    txt'), 'proguard-rules.pro'
        }
    }
}

repositories {
    maven {
        url "https://jitpack.io"
    }
    google()
}

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

}

您需要将-dontwarn或-ignorewarnings添加到proguard-rules.pro中的所有第三方库中。您可以在文档/维基页面上找到它们的说明
