Question

Android Studio 3.0.1，Gradle 4.1

我想在我的Android应用中生成QR。所以我尝试使用： com.google.zxing

项目的build.gradle中的

：

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'

        classpath "io.realm:realm-gradle-plugin:$REALM_VERSION"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$KOTLIN_VERSION"
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

/ appld.gradle：

implementation 'com.google.zxing:core:3.2.0'

但我得到错误：

错误：

Unable to resolve dependency for ':app@debugUnitTest/compileClasspath': Could not resolve com.google.zxing:core:3.2.0.

Could not resolve com.google.zxing:core:3.2.0.

Answer 1

或者您可以从here下载Android的ZXing core.jar文件，将该文件放入项目的libs文件夹中。

确保编译文件（'libs / android-core-3.2.0.jar'）在build.gradle文件中（或编译fileTree（dir：'libs'，include：'* .jar'）如果您使用的很多jar文件）

无法解析com.google.zxing：core：3.2.0
