我创建了一个使用的android应用程序android-support-v4.jar.现在当我向这个项目添加一个android库时,我在构建时遇到了这个错误:

UNEXPECTED TOP-LEVEL EXCEPTION:
java.lang.IllegalArgumentException: already added: Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoIcsImpl;
[2012-11-08 16:02:31 - ShoppingApp Android] Conversion to Dalvik format failed with error 1

我试图添加的库是Facebook SDK,它也碰巧使用android-support-v4.jar.我发现只有这个错误的解决方案是从一个构建路径中删除库,但我不能这样做 - 当我选择这个jar时,所有选项都被禁用.

这是完整的错误跟踪:

我正在开发多风格 Android 应用程序将 Android Gradle 插件更新到版本7.0.2（从“4.1.1”开始）以访问新的变体 API 后，我在应用程序构建过程中收到以下错误：

FAILURE: Build failed with an exception.

* What went wrong:
Some problems were found with the configuration of task ':app:injectCrashlyticsMappingFileIdRandstadAccDebug' (type 'InjectMappingFileIdTask').
- Type 'com.google.firebase.crashlytics.buildtools.gradle.tasks.InjectMappingFileIdTask' property 'mappingFileId' of mutable type 'org.gradle.api.provider.Property' is writable.

Reason: Properties of type 'org.gradle.api.provider.Property' are already mutable.

Possible solution: Remove the 'setMappingFileId' method.

Please refer to https://docs.gradle.org/7.0.2/userguide/validation_problems.html#mutable_type_with_setter for more details about this problem.
