在模块 jetified-com.google.zxing.client.android.captureactivity.jar 和 jetified-core-3.3.3.jar 中发现重复 class com.google.zxing.Binarizer

Question

所以我尝试了运行 ionic cordova run android 但我发现构建失败并出现异常。

Duplicate class com.google.zxing.Binarizer found in modules jetified-com.google.zxing.client.android.captureactivity.jar (com.google.zxing.client.android.captureactivity.jar) and jetified-core-3.3.3.jar (com.google.zxing:core:3.3.3) Duplicate class com.google.zxing.BinaryBitmap found in modules jetified-com.google.zxing.client.android.captureactivity.jar (com.google.zxing.client.android.captureactivity.jar) and jetified-core-3.3.3.jar (com.google.zxing:core:3.3.3) Duplicate class com.google.zxing.ChecksumException found in modules jetified-com.google.zxing.client.android.captureactivity.jar (com.google.zxing.client.android.captureactivity.jar) and jetified-core-3.3.3.jar (com.google.zxing:core:3.3.3) Duplicate class com.google.zxing.DecodeHintType found in modules jetified-com.google.zxing.client.android.captureactivity.jar (com.google.zxing.client.android.captureactivity.jar) and jetified-core-3.3.3.jar (com.google.zxing:core:3.3.3) Duplicate class com.google.zxing.EncodeHintType found in modules jetified-com.google.zxing.client.android.captureactivity.jar (com.google.zxing.client.android.captureactivity.jar) and jetified-core-3.3.3.jar (com.google.zxing:core:3.3.3) Duplicate class com.google.zxing.FormatException found in modules jetified-com.google.zxing.client.android.captureactivity.jar (com.google.zxing.client.android.captureactivity.jar) and jetified-core-3.3.3.jar (com.google.zxing:core:3.3.3) Duplicate class com.google.zxing.LuminanceSource found in modules jetified-com.google.zxing.client.android.captureactivity.jar (com.google.zxing.client.android.captureactivity.jar) and jetified-core-3.3.3.jar (com.google.zxing:core:3.3.3) Duplicate class com.google.zxing.MultiFormatReader found in modules jetified-com.google.zxing.client.android.captureactivity.jar (com.google.zxing.client.android.captureactivity.jar) and jetified-core-3.3.3.jar (com.google.zxing:core:3.3.3) Duplicate class com.google.zxing.MultiFormatWriter found in modules jetified-com.google.zxing.client.android.captureactivity.jar (com.google.zxing.client.android.captureactivity.jar) and jetified-core-3.3.3.jar (com.google.zxing:core:3.3.3) Duplicate class com.google.zxing.MultiFormatWriter found in modules jetified-com.google.zxing.client.android.captureactivity.jar (com.google.zxing.client.android.captureactivity.jar) and jetified-core-3.3.3.jar (com.google.zxing:core:3.3.3) Duplicate class com.google.zxing.NotFoundException found in modules jetified-com.google.zxing.client.android.captureactivity.jar (com.google.zxing.client.android.captureactivity.jar) and jetified-core-3.3.3.jar (com.google.zxing:core:3.3.3) Duplicate class com.google.zxing.PlanarYUVLuminanceSource found in modules jetified-com.google.zxing.client.android.captureactivity.jar (com.google.zxing.client.android.captureactivity.jar) and jetified-core-3.3.3.jar (com.google.zxing:core:3.3.3) Duplicate class com.google.zxing.RGBLuminanceSource found in modules jetified-com.google.zxing.client.android.captureactivity.jar (com.google.zxing.client.android.captureactivity.jar) and jetified-core-3.3.3.jar (com.google.zxing:core:3.3.3) Duplicate class com.google.zxing.Reader found in modules jetified-com.google.zxing.client.android.captureactivity.jar (com.google.zxing.client.android.captureactivity.jar) and jetified-core-3.3.3.jar (com.google.zxing:core:3.3.3)

Deprecated Gradle features were used in this build, making it incompatible with Gradle 7.0. Use '--warning-mode all' to show the individual deprecation warnings. See https://docs.gradle.org/6.5/userguide/command_line_interface.html#sec:command_line_warnings

这是我的 build.gradle 文件：

buildscript {
ext.kotlin_version = '1.3.50'
apply from: 'repositories.gradle'
repositories repos

dependencies {
    classpath 'com.android.tools.build:gradle:4.0.0'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
  }
  }

allprojects {
    apply from: 'repositories.gradle'
    repositories repos

project.ext {
  defaultBuildToolsVersion="29.0.2" //String
  defaultMinSdkVersion=22 //Integer - Minimum requirement is Android 5.1
  defaultTargetSdkVersion=29 //Integer - We ALWAYS target the latest by default
  defaultCompileSdkVersion=29 //Integer - We ALWAYS compile with the latest by default
}
}

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

我试过了：

添加：configurations {compile.exclude group: 'com.google.zxing'} 到 build.gradle
从 cordova 中删除了 android 平台，然后又添加了它。
删除了 barcodescanner 插件然后添加它。

我已经坚持了将近一个星期了。

问题是由于facebook4插件和barcodeScanner插件之间的冲突造成的。两者都使用名为 ZXing 的库，这会导致冲突。

简单的解决方法（很难找到）是删除 facebook 插件并添加没有 zxing 库的相同插件。

ionic cordova platform rm android
ionic cordova plugin rm cordova-plugin-facebook4 --save --variable APP_ID="ID" --variable APP_NAME="NAME"
ionic cordova plugin add https://github.com/AndreiTelteu/cordova-plugin-facebook4-no-zxing --save --variable APP_ID="ID" --variable APP_NAME="NAME"
ionic cordova platform add android
ionic cordova platform rm android

这解决了我的问题。请注意，您的代码中没有可编辑的内容。
