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：

这些是涉及的Gradle脚本的内容(我已经用’com.myapp.ID’替换了实际的applicationID)

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,并且可以正常工作,因此,我认为这是可以接受的解决方法,至少在firebase家伙发布了firebase-core 16.0.6或与之实际兼容的情况下firebase-ads 17.0.0.问题似乎有效地在于,firebase-ads 17.0.0依赖于导致错误的较旧版本的库.
查看以下依赖项输出：
这是我用firebase-core 16.0.4得到的：

解决方法:
好吧,既然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,那么这里是：
您的错误消息使我的搜索达到com.android.tools.r8.errors.CompilationError: Program type already present: androidx.annotation.AnimRes
Caused by:

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以生成依赖项的树/列表以查找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只是一个提示.
这使我注意到核心和广告具有相似之处：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
>将排除组：“ com.Google.androID.gms”,模块：“ play-services-measurement-sdk-API”添加到广告依赖项
第一种选择可能更安全,因为重新运行./gradlew app：dependencIEs显示play-services-measurement-API和play-services-measurement-sdk-API现在都为16.0.2.
而且我确定Google / Firebase知道了这一点,因为我在https://issuetracker.google.com/issues/119213680处又找到了它.翻译是：错误是zzdz类的重复,zzdz类的存在状态的转换如下.因此,请注意play-services-measurement-sdk-API可能会遇到其他Firebase / GMS库的问题.应该有一个即将发布的修复程序来更新它.
*请注意,即使切换到“ com.Google.firebase：firebase-ads：17.1.0”仍会导致此错误.
