android - 添加指示重复类的新依赖项后项目构建失败

问题描述

我正在处理我的应用程序一切都很好，直到我想添加一个条形码扫描仪，当我添加这个时implementation 'info.androidhive:barcode-reader:1.1.5'

我的应用程序开始无法构建并出现此错误：

Go to the documentation to learn how to Fix dependency resolution errors.

当然，转到文档链接不会带我去任何地方。

这也是我的 gradle 依赖项：

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation 'com.jakewharton:butterknife:9.0.0'
annotationProcessor 'com.jakewharton:butterknife-compiler:9.0.0'

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'
implementation 'com.google.android.gms:play-services-vision:17.0.2'
implementation 'org.jetbrains:annotations-java5:15.0'
implementation 'com.android.support:recyclerview-v7:28.0.0'
implementation 'com.squareup.retrofit2:retrofit:2.1.0'
implementation 'com.squareup.retrofit2:converter-gson:2.1.0'
implementation `'info.androidhive:barcode-reader:1.1.5'`
}

当我删除'info.androidhive:barcode-reader:1.1.5'依赖项时，它构建得很好（但我需要它）。我不知道要删除什么或做什么，感谢任何提示。

解决方案

由于传递依赖，您有两个版本的相同工件。

从工件中排除com.android.support组。barcode-reader

implementation ('info.androidhive:barcode-reader:1.1.5'){
        exclude group: "com.android.support"
}
