FAILURE: Build failed with an exception.

* Where:
Script 'node_modules\react-native\react.gradle' line: 191

* What went wrong:
Execution failed for task ':app:bundleReleaseJsAndAssets'.
> Process 'command 'cmd'' finished with non-zero exit value 1

(至少在生成失败之后，引用的文件仍然存在)。

环境

• 基于Windows 10的构建
• React原生版本: 0.62.2

我想做的事

• 尝试将soLoader提高到0.8.0和0.8.2 (尽管在RN0.62.2中不应该需要这一点)，正如https://github.com/facebook/react-native/issues/25927#issuecomment-539415154中所建议的那样

Answer 1

在build.gradle中修改以下额外的包定义：

extraPackagerArgs: ["--sourcemap-output", "$buildDir/intermediates/assets/release/index.android.bundle.map"]

至

extraPackagerArgs: ["--sourcemap-output", "$buildDir/intermediates/sourcemaps/react/release/index.android.bundle.packager.map"]

修正了错误(警告仍然存在)。

创建了一个APK并正在运行。

Answer 2

./gradlew clean

做完./梯度清理后，我觉得很管用。

或

适用于Windows：

gralde clean
