我正在使用VS代码。所有其他项目都运行良好。我正在实际设备上运行项目与命令"flutter run"从终端。为什么我得到这个错误:
失败:生成失败,出现异常.

  • 其中:构建文件"C:\Users\hp\Documents\flutter-mobile-app\android\app\build. gradle"行:24
  • 问题:评估项目':app'时出现问题。无法初始化类com. android. build. gradle. internal. TaskManager

这是我的app/build. gradle

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主目录,在此之前我使用的是jdk 1.8.0_291**

和我的Gradle属性:

您能否尝试classpath 'com.android.tools.build:gradle:4.1.0'并运行应用程序
如果问题仍然存在,请使用以下内容创建新应用程序并提供日志
它应该工作,确保您的java版本是最新的,而不是像java8或9旧
