FAILURE：构建失败并出现异常。 （扑）

Question

当我尝试构建我的 Flutter 项目时，我遇到了这个问题。

FAILURE：构建失败并出现异常。

• 出了什么问题：配置项目“：flutter_string_encryption”时出现问题。

  未能通知项目评估侦听器。 java.lang.AbstractMethodError（无错误信息）

当我在项目级别打开我的 Gradle 文件时，GradleException Function 突出显示无法解析符号的错误。这是我的 Gradle 文件代码。

def localProperties = new Properties()  //Here Error of Properties can't resolve
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) {
//Here is error of GradleException Can't resolve on below line
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'
}

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

android {
    compileSdkVersion 28

    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.hbr.food_delivery_admin_app"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }
}

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'
}

请帮助我如何解决它？

在 GradleException 之前删除 new 关键字。

throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")

并且请避免问这个问题，它已经遍布stackoverflow了。
