FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':fluttertoast:compileDebugJavaWithJavac'.
Compilation failed; see the compiler error output for details.

BUILD FAILED in 6sThe built failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetfier to solve the incompatibility. [!] Flutter tried to create the file `android\settings_aar.gradle`, but failed. To manually update `settings.gradle`, follow these steps: 1. Copy `settings.gradle` as `settings_aar.gradle` 2. Remove the following code from `settings_aar.gradle`: def flutterProjectRoot = rootProject.projectDir.parentFile.toPath() def plugins = new Properties() def pluginsFile = new File(flutterProjectRoot.toFile(), '.flutter-plugins') if (pluginsFile.exists()) { pluginsFile.withReader('UTF-8') { reader -> plugins.load(reader) } } plugins.each { name, path -> def pluginDirectory = flutterProjectRoot.resolve(path).resolve('android').toFile() include ":$name" project(":$name").projectDir = pluginDirectory } Please create the file and run this command again.
这是我的应用级 build.gradle

}
}
def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}
def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
flutterVersionCode = '1'
}
def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
flutterVersionName = '1.0'

非常感谢任何帮助。
最佳答案
问题似乎与项目或插件未使用 Android X 有关。要检查 Flutter 项目是否使用 Android X,请按照此 guide 进行操作。从文档。如果 Flutter 项目还没有使用 Android X,请关注这个 migration guide .另一方面,如果插件导致问题,请尝试使用其最新版本并查看最新版本现在是否使用 Android X。
