任务 ':app:checkDebugDuplicateClasses' 执行失败。 Ionic4 Android

Question

我目前正在开发一个 ionic4 应用程序，但最近在向应用程序添加 https://ionicframework.com/docs/native/fcm 插件后，在 android 真实设备上构建应用程序时它停止工作。

起初它抱怨 fabric key，但我从来没有打算在我的应用程序上使用 fabric crashlytic。

错误日志：

Answer 1

您的项目（或其 sub-projects 中的一个项目）指的是在其末尾使用 + (plus-sign) 的依赖项，例如 com.google.firebase:firebase-auth:+，这意味着尽可能使用任何更高版本，并且较新的版本不再使用 android.support 库，而是使用 androidx；要解决此问题，请按照以下步骤操作。

步骤：

确保 ANDROID_HOME environment-variable 已设置，然后打开控制台 window（如 git-bash，因为它保留了整个命令输出），并且 cd 进入你的 android 目录（对于 Ionic 项目，它应该是 platforms/android）。
首先，列出下面运行的所有依赖项（在 git-bash 中）：
```
./gradlew :app:dependencies
```
将结果复制到您的首选 text-editor，然后搜索 androidx。
如果您发现了一些东西，请按照以下步骤操作，否则您就完成了！（并且您不需要重复这些步骤）。
向上滚动，直到在任何行的末尾看到 ->，例如 16.0.8 -> 19.0.0 或 + -> 19.0.0，这两者都意味着版本是 auto-resolved（由于 + 而高于您指定的版本）。
所以，手动设置版本：
- 如果可能，在您的项目中找到 + 符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。
最后，重复上述步骤（但不是第一步，只是 clear 控制台）。

要强制依赖项的特定版本 添加到您的根 build.gradle 类似下面的内容（这对我有用）但是编辑并添加您自己的规则（如果这些对你不起作用）：

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 2

我在使用 Android Studio 功能迁移到 Androidx 时遇到了这个问题，但第一次迁移不成功，所以每次我尝试编译时我 [=18= 】进入这个问题。

为了解决这个问题，我做了以下工作：

[1] Comment all androidx dependencies in the app bundle.gradle file
[2] Try the Migrate to Androidx. You can see this link in Refactor -> Migrate to Androidx. If the migration was successful, then
[3] Uncomment all androidx dependencies in the app bundle.gradle file

您可以重新清理并构建您的项目，希望这个错误应该消失。

Answer 3

就我而言，我在应用级别 build.gradle 文件的依赖项部分下删除了此实现 -

implementation 'com.google.android.gms:play-services-ads:19.2.0'

删除或注释掉！！

Answer 4

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

Answer 5

我遇到了同样的问题，但我按如下方式解决了。打开 Android 工作室> 文件 > 无效 Caches/Restart…

Answer 6

我遇到了同样的问题，我的解决方案如下：

转到 gradle.properties 个文件

添加这两行：

android.useAndroidX=true
android.enableJetifier=true

重建您的项目。

就是这样。

注意： 如果您的项目已经显示此 android.useAndroidX=true 那么只需添加 android.enableJetifier=true 并重建您的项目。

Answer 7

转到gradle.properties（项目属性）
添加
android.enableJetifier=true
而且大部分时间 android.useAndroidX=true 是 present.Check 您的 gradle.properties（项目属性），如果它不存在，则添加
android.useAndroidX=true -> 看起来喜欢这张图片

Answer 8

只需将以下行添加到您的 `gradle.properties` 文件中：

android.useAndroidX=true
android.enableJetifier=true

Note to check, to not repeat any line that already exists (and ensure existing are true).

详情

如果要在新项目中使用androidx命名空间库，需要将编译SDK设置为Android9.0（API28级）或更高版本并设置两个提到的 Android Gradle 插件标志到 true.

android.useAndroidX：当这个标志设置为true时，Android插件使用适当的AndroidX库而不是支持库。如果不指定，标志默认为false。

android.enableJetifier：当这个标志设置为true时，Android插件会自动迁移现有的第三方库以使用AndroidX 依赖重写它们的二进制文件。如果不指定，标志默认为false。

Answer 9

我认为您在 gradle.properties 中多次保留同一个标签，如下所示

    org.gradle.jvmargs=-Xmx4g -XX:MaxPermSize=2048m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
    org.gradle.jvmargs=-Xmx4608m

Answer 10

在我的 Ionic 项目中，我需要删除行

cordova.system.library.19=com.google.android.gms:play-services-analytics:11.0.1

从我的 /platforms/android/project.properties 获取构建

Answer 11
