在构建Flutter应用程序时，Gradle突然开始出错

时间：2018-05-06 06:35:59

标签： android gradle build.gradle flutter

这是我在运行Android 8.1的x86 android模拟器上运行我的Flutter应用程序时收到的错误

Launching lib\main.dart on Android SDK built for x86 in debug mode...
Initializing gradle...
Resolving dependencies...
Running 'gradlew assembleDebug'...
registerResGeneratingTask is deprecated, use registerGeneratedResFolders(FileCollection)
registerResGeneratingTask is deprecated, use registerGeneratedResFolders(FileCollection)
registerResGeneratingTask is deprecated, use registerGeneratedResFolders(FileCollection)

FAILURE: Build failed with an exception.

* What went wrong:
Failed to capture snapshot of input files for task ':app:packageDebug' property 'javaResourceFiles' during up-to-date check.
> java.lang.IllegalStateException: Expected BEGIN_ARRAY but was STRING at line 1 column 1 path $

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 6s
Finished with error: Gradle build failed: 1
  

使用--stacktrace选项运行以获取堆栈跟踪。使用--info或--debug选项运行以获取更多日志输出。使用--scan运行以获得全面的见解。

问题是我不知道Android Studio正在运行什么命令来向其添加stacktrace选项。

编辑：我必须运行＆＃39; gradlew assembleDebug --stacktrace＆＃39; （非常明显）。

得到了它的输出，但不知道如何解决它。

* Exception is:
org.gradle.api.UncheckedIOException: Failed to capture snapshot of input files for task ':app:packageDebug' property 'javaResourceFiles' during up-to-date check.

升级所有软件包和flutter clean都是神奇的。
