更新Gradle依赖项后生成错误。嫌疑人1是火力发源地
我有一个构建良好的应用程序，但是当我尝试更新某些Gradle依赖项时就开始失败，而主要的怀疑对象是firebase。
这是我得到的错误：
原因： com.android.builder.multidex.D8MainDexList $ MainDexListException： com.android.tools.r8.errors.CompilationError：程序类型已经 礼物：com.google.android.gms.internal.measurement.zzdz
这是我项目的git diff，显示了Gradle文件中的差异：

请注意，其中某些更改（例如minSDKVersion）可以作为错误源丢弃。似乎最有可能与firebase有关。为什么？好吧，在Stackoverflow中还存在其他问题，但是所有这些中提出的解决方案都是将firebase依赖关系更新到最新版本，但是将firebase依赖关系更新到最新版本似乎是这样。导致我的项目出现问题！使用旧版本，它可以正常运行。
这些是所涉及的Gradle脚本的内容（我已经用'com.myapp.id'代替了实际的applicationId）

最后，这是我项目的结构。与android相关的最相关的部分是顶部。下面我只显示它与核心模块的关系。
这是一个libGDX游戏，我正在使用IntelliJ Idea，尽管这无关紧要，因为我在命令行中使用./gradlew构建时遇到了这些错误。
编辑：我按照TWL的建议将firebase-core从16.0.5降级到16.0.4，并且它起作用了，所以我认为这是一个可以接受的解决方法，至少在firebase家伙发布了firebase-core 16.0.6左右的时候实际上与firebase-ads 17.0.0兼容。问题似乎很有效，因为firebase-ads 17.0.0依赖于导致错误的较旧版本的库。
看看这些依赖项输出：
这是我使用firebase-core 16.0.4的结果：

如您所见，尽管我不太精通，但仍有一些条目，例如“ com.google.android.gms：play-services-measurement-base：16.0.3-> 16.0.4（*）”解释这些输出，我认为是问题的原因。

好吧，由于所有评论都移到了聊天中，并且我的临时解决方法也在那里，所以现在是：
您的错误消息将我的搜索带到了com.android.tools.r8.errors.CompilationError: Program type already present: androidx.annotation.AnimRes
原因： com.android.builder.multidex.D8MainDexList $ MainDexListException： com.android.tools.r8.errors.CompilationError：程序类型已经 目前：___
该错误表明某个地方存在重复的依赖关系，该依赖关系运行于两个不同的版本。然后的目标是运行./gradlew app:dependencies来生成依赖项的树/列表以寻找com.google.android.gms.internal.measurement.zzdz。问题在于，这是一个模糊的内部私有包，因此无法在列表中直接找到它，但是关键字measurement是一个提示。
这使我注意到core和ads具有相似的内容：play-services-measurement-api:[16.0.3] -> 16.0.3 (*)和play-services-measurement-sdk-api:16.0.2。通过测试，我发现了两种解决方法：
- 将
com.google.firebase:firebase-core:16.0.5降级为16.0.4 - 将
exclude group: 'com.google.android.gms', module: 'play-services-measurement-sdk-api'添加到ads依赖项
第一个选项可能更安全，因为重新运行./gradlew app:dependencies表明play-services-measurement-api和play-services-measurement-sdk-api现在都是16.0.2
我敢肯定Google / Firebase知道这一点，因为我确实在https://issuetracker.google.com/issues/119213680上找到了另一个提及。翻译是：该错误与zzdz类重复，存在的过渡zzdz类的状态如下。请注意，play-services-measurement-sdk-api可能会与其他Firebase / GMS库发生问题。应该有一个即将发布的修复程序来对其进行更新。
*请注意，即使切换到"com.google.firebase:firebase-ads:17.1.0"仍然会导致此错误。
