任务'：app：checkDebugDuplicateClasses'的执行失败。Ionic4安卓

Question

我目前正在处理ionic4应用程序，但是最近在向应用程序添加https://ionicframework.com/docs/native/fcm插件后，在android reall设备上构建该应用程序时，它停止了工作。

起初它抱怨结构密钥，但是我从来没有打算在我的应用程序上使用结构崩溃解决。

错误日志：

Answer 1

The issue I was facing was in the react-native something similar to

Execution failed for task ':app:checkDebugDuplicateClasses'.

1 exception was raised by workers: java.lang.RuntimeException: java.lang.RuntimeException: Duplicate class kotlin.collections.jdk8.CollectionsJDK8Kt found in modules jetified-kotlin-stdlib-1.8.0.jar (org.jetbrains.kotlin:kotlin-stdlib:1.8.0) and jetified-kotlin-stdlib-jdk8-1.6.21.jar (org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.6.21) Duplicate class kotlin.internal.jdk7.JDK7PlatformImplementations found in modules jetified-kotlin-stdlib-1.8.0.jar (org.jetbrains.kotlin:kotlin-stdlib:1.8.0) and jetified-kotlin-stdlib-jdk7-1.6.21.jar (org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.6.21)

It means that there is a conflict between two different versions of the Kotlin standard library, specifically the "jetified-kotlin-stdlib-1.8.0.jar" and "jetified-kotlin-stdlib-jdk8-1.6.21.jar" versions. The error message specifically states that there is a duplicate class "kotlin.collections.jdk8.CollectionsJDK8Kt" found in both versions.

and the solution was here there were two approaches but i found this one easier go to android/app/build.gradle and update the dependencies

dependencies {
constraints {
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.8.0") {
        because("kotlin-stdlib-jdk7 is now a part of kotlin-stdlib")
    }
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.8.0") {
        because("kotlin-stdlib-jdk8 is now a part of kotlin-stdlib")
    }
}

Answer 2

1. 转到 gradle.properties（项目属性）

2. 添加
   android.enableJetifier=true

3. 而且大部分时间android.useAndroidX=true都存在。检查您的 gradle.properties(Project Properties)，如果它不存在，则添加
   android.useAndroidX=true-> Look Likes This Image

Answer 3

只需将以下行添加到您的gradle.properties文件中：

\n

android.useAndroidX=true\nandroid.enableJetifier=true\n

\n

\n

请注意检查，不要重复任何已存在的行（并确保现有的是true）。

\n

\n

最后，重建你的项目。

\n

\n

但有时您可能需要手动删除该build文件夹。

\n

\n\n

细节

\n

您的项目（或其子项目之一或依赖项）不再使用\xc2\xa0 android.support\xc2\xa0libraries，而是使用\xc2\xa0androidx库，如果与\xc2\xa0libraries 混合，则会导致冲突android.support。

\n

如果您想androidx在旧项目中使用命名空间库，则需要将编译 SDK 设置为 Android 9.0（API 级别 28）或更高版本但低于“API 级别 31”，并将上述两个 Android Gradle 插件标志设置为true.

\n

android.useAndroidX：当此标志设置为 时true，Android 插件使用适当的 AndroidX 库而不是支持库。false如果未指定，则默认使用该标志。

\n

android.enableJetifier：当此标志设置为 时true，Android 插件会自动迁移现有的第三方库，以通过重写二进制文件来使用 AndroidX 依赖项。false如果未指定，则默认使用该标志。

\n

Answer 4

我遇到了同样的问题，我的解决方案如下：

1. 转到 gradle.properties 文件

2. 添加这两行：

   android.useAndroidX=true
   android.enableJetifier=true
   

3. 重建您的项目。

就是这样。

注意：如果您的项目已显示此内容android.useAndroidX=true，则只需添加android.enableJetifier=true并重建您的项目即可。

Answer 5

您的项目（或其子项目之一）在末尾使用+加号来引用依赖项，例如com.google.firebase:firebase-auth:+，这意味着，尽可能使用任何更高版本，而较新的版本不再使用android.support库，而是使用androidx; 要解决此问题，请执行以下步骤。

脚步：

1. 确保设置了ANDROID_HOME环境变量，然后打开控制台窗口（如git-bash，因为它保留了整个命令的输出），并cd进入您的android目录（对于Ionic项目，应为platforms/android）。
2. 首先，通过在下面运行（在git-bash中）列出所有依赖项：

   ./gradlew :app:dependencies
   

3. 将结果复制到您首选的文本编辑器中，然后搜索androidx。
4. 如果发现有问题，请执行以下步骤，否则就完成了！（并且您无需重复这些步骤）。
5. 向上滚动直到在任何行的末尾看到->，例如example 16.0.8 -> 19.0.0或+ -> 19.0.0，这都意味着该版本是自动解析的（由于+，其版本比您指定的要高）。
6. 因此，手动设置版本：
   • 在可能的情况下，在您的项目中找到+号并将其替换为特定版本。
   • 或者，强制使用特定版本的依赖项，如下所述。
7. 最后，重复上述步骤（而不是第一步，而是clear控制台）。

要强制特定版本的依赖项，请在您的根目录中添加build.gradle以下内容（对我有用），但要编辑并添加自己的规则（如果这些规则对您不起作用）：

allprojects {
  // ...
  configurations.all {
    resolutionStrategy {
      force 'com.google.firebase:firebase-common:17.0.0'
      force 'com.google.android.gms:play-services-basement:16.2.0'
      force 'com.google.firebase:firebase-iid:16.0.0'
      force 'com.google.firebase:firebase-auth:17.0.0'
    }
  }
}

Answer 6

对我来说，只需安装插件“cordova-plugin-androidx”和“cordova-plugin-androidx-adapter”就解决了这个问题：

$ ionic cordova plugin add cordova-plugin-androidx
$ ionic cordova plugin add cordova-plugin-androidx-adapter
