当我在 Android Studio 中进行增量构建时，Firebase Crashlytics 崩溃 'The Crashlytics build ID is missing'
When I'm doing an incremental build in Android Studio, Firebase Crashlytics crashes with 'The Crashlytics build ID is missing'
我正在我的 Android 应用程序中添加 Firebase Crashlytics。我仔细按照 https://firebase.google.com/docs/crashlytics/get-started?platform=android.
中的说明进行操作
当我重建 运行 应用程序（在 Android Studio 中）时，一切正常，我能够收到崩溃报告。
但是：当我在 Android Studio 中对我的代码进行一些更改并重新 运行 应用程序时，它崩溃并显示以下报告。

Gradle may disable incremental compilation as the following annotation processors are not incremental: databinding-compiler-3.4.1.jar (androidx.databinding:databinding-compiler:3.4.1).
Consider setting the experimental feature flag android.enableSeparateAnnotationProcessing=true in the gradle.properties file to run annotation processing in a separate task and make compilation incremental.

同样的问题，已通过将 Crashlytics Gradle 插件版本降级到 2.1.1 来解决。
Crashlytics Gradle 插件版本 2.2.0
firebase-crashlytics-gradle 的此更新包括对 Crashlytics 任务配置和依赖项声明的几处更改，这提高了增量构建性能并修复了几个已知问题。
如果您想升级 Crashlytics Gradle v2.2.0+，请先尝试升级您的 gradle 版本
在 gradle/wrapper/gradle-wrapper.properties 文件中，将您的 gradle 版本升级到 5.6.4
distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.4-all.zip
我曾经 运行 我的应用使用 gradle 5.1.1，升级到版本 5.6.4 解决了我的问题

Gradle may disable incremental compilation as the following annotation processors are not incremental: databinding-compiler-3.4.1.jar (androidx.databinding:databinding-compiler:3.4.1).
Consider setting the experimental feature flag android.enableSeparateAnnotationProcessing=true in the gradle.properties file to run annotation processing in a separate task and make compilation incremental.

同样的问题，已通过将 Crashlytics Gradle 插件版本降级到 2.1.1 来解决。
Crashlytics Gradle 插件版本 2.2.0 firebase-crashlytics-gradle 的此更新包括对 Crashlytics 任务配置和依赖项声明的几处更改，这提高了增量构建性能并修复了几个已知问题。
如果您想升级 Crashlytics Gradle v2.2.0+，请先尝试升级您的 gradle 版本
在 gradle/wrapper/gradle-wrapper.properties 文件中，将您的 gradle 版本升级到 5.6.4
distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.4-all.zip
我曾经 运行 我的应用使用 gradle 5.1.1，升级到版本 5.6.4 解决了我的问题
希望对您有所帮助！
