Android Flatter找不到org.gradle.api.project类型的项目“：app”上参数[]的方法属性（）

输出：

mac@Macs-MacBook Air credapp%颤振运行 正在调试模式下启动SM N950U上的lib/main.dart

失败：生成失败，出现异常

其中： 构建文件“/Users/mac/Documents/flatter_Project/credapp/android/app/Build.gradle”行：28

出了什么问题： 评估项目“：app”时出现问题

在类型为org.gradle.api.project的项目“：app”上找不到参数[]的方法属性

尝试： 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运行以获得完整的洞察力

得到更多的帮助

在出现问题的地方添加“new”关键字

对我来说

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 = '44'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '4.4'
}

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

def keystoreProperties = Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(FileInputStream(keystorePropertiesFile))
}


android {
    compileSdkVersion 29

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    lintOptions {
        disable 'InvalidPackage'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.credfinance.credfinance"
        minSdkVersion 19
        targetSdkVersion 29
        versionCode 44
        versionName '4.4'
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    signingConfigs {
        release {
            keyAlias keystoreProperties['keyAlias']
            keyPassword keystoreProperties['keyPassword']
            storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
            storePassword keystoreProperties['storePassword']
        }
   }
   buildTypes {
       release {
           signingConfig signingConfigs.release
       }
   }
}

flutter {
    source '../..'
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
}

这是投掷错误

if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(  FileInputStream(keystorePropertiesFile))} 

已保存日期

您是否尝试将def KESTOREPROPERTIES=属性更改为def KESTOREPROPERTIES=新属性？

if (keystorePropertiesFile.exists()) {
    keystoreProperties.load( new FileInputStream(keystorePropertiesFile))}
