FAILURE: Build failed with an exception.

我的构建脚本：

buildscript {
    ext {
        buildToolsVersion = "29.0.2"
        minSdkVersion = 16
        compileSdkVersion = 29
        targetSdkVersion = 29
    }
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath('com.android.tools.build:gradle:3.5.3')
    }
}

简短的解决方案：

\n

如果您使用ReactNative <= 0.63，请安装react-native-safe-area-context在V3（例如3.4.1）中，因为它与v4不兼容safe-area-context

\n\n

漫长而痛苦的旅程，这也解决了我途中的一些其他错误：

\n

这可以帮助我解决它：

\n

首先，设置您的构建脚本版本：

\n

\n
• minSdkVersion = 24（即 Android 7 [nougat]）
\n
• 目标SdkVersion =
\n
• compileSdkVersion = 31（此处设置最新可能）
\n

\n

解释这些版本的作用：\n| 标题 | 另一个标头 |\n| -------- | -------------- |\n| minSdkVersion | 设置您希望应用程序支持的最低 Android 版本。但请记住，您的应用程序\xe2\x80\x99s minSdkVersion 必须至少与您的依赖要求一样高
Google Play 商店还使用此来确定应用程序可以在用户\xe2\x80\x99s 设备中使用安装在 |\n| 目标SdkVersion | 这是 Android 提供前向兼容性的主要方式，除非更新 targetSdkVersion，否则不应用行为更改 |\n| 编译SdkVersion| 是您的应用程序将使用的版本进行编译。更改此值不会更改运行时行为，您的compileSdkVersion不包含在您的APK中|

\n

如果您想了解更多相关信息，请参阅此处

\n

注意：如果您增加compileSdkVersion，请确保您还在电脑上安装了新的SDK。\n就我而言，我错过了这一点，并收到了一个无帮助的错误，例如：

\n

* Where:\nBuild file \'/home/me/myProject/android/app/build.gradle\' line: 130\n\n* What went wrong:\nA problem occurred evaluating project \':app\'.\n> No signature of method: build_bzoaxr1mlfb80yiyz2yt0w97u.android() is applicable for argument types: (build_bzoaxr1mlfb80yiyz2yt0w97u$_run_closure1) values: [build_bzoaxr1mlfb80yiyz2yt0w97u$_run_closure1@1068678f]\n\n

\n

例如在 Android-Studio 中它看起来像这样：

\n

然后看看升级gradle-plugin。

\n

https://developer.android.com/studio/releases/gradle-plugin.html#updating-gradle

\n

升级 Gradle 后，出现此错误：

\n

10:01   Gradle sync failed: Could not get unknown property \'compile\' for configuration container of type org.gradle.api.internal.artifacts.configurations.DefaultConfigurationContainer. (3 s 273 ms)\n

\n

所以我已经from configurations.compile改为implementation：android/app/build.gradle

\n

* Where:\nBuild file \'/home/me/myProject/android/app/build.gradle\' line: 130\n\n* What went wrong:\nA problem occurred evaluating project \':app\'.\n> No signature of method: build_bzoaxr1mlfb80yiyz2yt0w97u.android() is applicable for argument types: (build_bzoaxr1mlfb80yiyz2yt0w97u$_run_closure1) values: [build_bzoaxr1mlfb80yiyz2yt0w97u$_run_closure1@1068678f]\n\n

\n

然后gradle-sync成功，没有错误。

\n

正如我在中所做的那样，android studio我已经清除了项目 buy run > clean project，但您也可以转到/android并运行./gradlew clean

\n

但当我尝试启动应用程序时，遇到了问题。在 stackoverflow 上搜索了一下，原因似乎是 RN 仍然与 Gradle7 不兼容。\n所以回到 6.9：

\n

10:01   Gradle sync failed: Could not get unknown property \'compile\' for configuration container of type org.gradle.api.internal.artifacts.configurations.DefaultConfigurationContainer. (3 s 273 ms)\n

\n

我还必须将 build:gradle-tools 更改为 4.2.2

\n

dependencies {\n        classpath(\'com.android.tools.build:gradle:4.2.2\')\n}\n

\n
