无法解析 org.jetbrains.kotlin:kotlin-gradle-plugin:1.4.10

Question

我是 Android 编程的新手，但对 Flutter 并不陌生。到目前为止，我一直在 iOS 上进行测试。现在，当我想在 Android 上进行测试时，我遇到了这个问题：

FAILURE: Build failed with an exception.

BUILD FAILED in 6s
Exception: Gradle task assembleDebug failed with exit code 1

这是我的android/build.gradle：

buildscript {
    ext.kotlin_version = '1.4.10'
    repositories {
        google()  // Google's Maven repository
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.0.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.3'
    }
}

allprojects {
    repositories {
        google()  // Google's Maven repository
        jcenter()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

由于我对 android 及其问题不是很熟悉，如果我需要在此问题中包含其他任何内容，请告诉我。

谢谢

Answer 1

由于 Jcenter() 现在在 2021 年已弃用，您可以在项目级别 Gradle 中添加 mavencentral 作为

repositories {
        google()
        mavenCentral()
    }

Answer 2

脚本中的所有依赖项请求最终都会出现相同的错误

连接到 127.0.0.1:1088 [/127.0.0.1] 失败：连接被拒绝（连接被拒绝）

您可能已将系统配置为使用本地代理服务器，但它实际上并未在该 1088 端口上运行。
