我正在使用VS Code。所有其他项目都运行良好。我正在终端上使用命令“flutter run”在真实设备上运行项目。为什么会出现以下错误:
失败:构建异常。
- 位置: 构建文件'C:\ Users \ hp \ Documents \ flutter-mobile-app \ android \ app \ build.gradle'第24行
- 出了什么问题: 评估项目时发生问题':app'。 无法初始化com.android.build.gradle.internal.TaskManager类
这是我的app/build.gradle文件
def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
localPropertiesFile.withReader('UTF-8') { reader ->
localProperties.load(reader)
}
}
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'
}

我的Java Home,在此之前我使用的是jdk 1.8.0_291
以及我的Gradle属性:
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-7.4-all.zip
flutter doctor
来获取更多的见解,或者直接运行gradle命令gradlew assemble --stacktrace
(或类似命令)。 - dpr
