Question

我尝试运行我的第一个 firebase 应用程序，但由于此错误而无法运行：

FAILURE：构建失败，出现异常。

哪里：构建文件 'C:\Users\boras\OneDrive\Masaustu\Software\ProgramlamaTemelliYazilim\Flutter\firebase_application\firebase_application\android\app\build.gradle' 行：29
出了什么问题：评估项目“:app”时出现问题。

方法的无签名：）build_884xt67ny8crpgv70jgbem96p.android（为参数类型是适用的：（build_884xt67ny8crpgv70jgbem96p $ _run_closure2）值：[build_884xt67ny8crpgv70jgbem96p $ ure2）值：[build_884xt67ny8crpgv70jgbem96p $ _run_closure2 @ 1998e9ac]

试试：使用 --stacktrace 选项运行以获取堆栈跟踪。使用 --info 或 --debug 选项运行以获得更多日志输出。使用 --scan 运行以获得完整的见解。

这就是我 android/app/build.gradle 的样子：

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'
}

Answer 1

尝试更改您的以下版本：

compileSdkVersion 28

minSdkVersion 21

targetSdkVersion 30

评估项目“:app”时出现问题。构建gradle问题
