android - 程序类型已经存在 : com. google.zxing.ChecksumException

Question

我尝试使用 zxing 库扫描二维码，直到我像这样运行应用程序之前没有错误:

Program type already present: com.google.zxing.ChecksumException

Message{kind=ERROR, text=Program type already present: com.google.zxing.ChecksumException, sources=[Unknown source file], tool name=Optional.of(D8)}

这是我的gradle:

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.std.scanner"
        minSdkVersion 18
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support:design:26.1.0'
    implementation 'com.journeyapps:zxing-android-embedded:3.6.0'
}

我想我应该在我的 gradle 依赖项中使用“排除”，但我不知道如何编写代码。请帮忙，提前致谢。

在build.gradle(app)中添加解决

configurations {
    implementation.exclude group: 'com.google.zxing'
}
