当Flutter下载依赖慢，运行在Android上卡Running Gradle task ‘assembleDebug...解决方法

Flutter运行在Android上卡Running Gradle task 'assembleDebug'...，是因为无法访问官方源，下面是换源方法。

一、修改flutter及gradle配置文件

1、修改resolve_dependencies.gradle.kts文件,将repositories中的镜像源更改为国内

groovy 复制代码

import java.nio.file.Paths

// This script is used to warm the Gradle cache by downloading the Flutter dependencies
// used during the build. This script is invoked when `flutter precache` is run.
//
// Command:
//  gradle -b <flutter-sdk>packages/flutter_tools/gradle/resolve_dependencies.gradle.kts
//      resolveDependencies
//
// This way, Gradle can run with the `--offline` flag later on to eliminate any
// network request during the build process.
//
// This includes:
//   1. The embedding
//   2. libflutter.so

val storageUrl: String = System.getenv("FLUTTER_STORAGE_BASE_URL") ?: "https://storage.googleapis.com"

val flutterRoot = projectDir.parentFile?.parentFile?.parentFile
requireNotNull(flutterRoot) { "Flutter root directory not found!" }

require(flutterRoot.isDirectory) { "Flutter root is not a valid directory!" }

val engineVersion =
    Paths
        .get(
            flutterRoot.absolutePath,
            "bin",
            "cache",
            "engine.stamp"
        ).toFile()
        .readText()
        .trim()

var engineRealm =
    Paths
        .get(
            flutterRoot.absolutePath,
            "bin",
            "cache",
            "engine.realm"
        ).toFile()
        .readText()
        .trim()

if (engineRealm.isNotEmpty()) {
    engineRealm += "/"
}

repositories {
    maven { url = uri("https://maven.aliyun.com/repository/gradle-plugin") }
    maven { url = uri("https://maven.aliyun.com/repository/google") }
    maven { url = uri("https://maven.aliyun.com/repository/public") }
    maven {
        url = uri("$storageUrl/${engineRealm}download.flutter.io")
    }
}

configurations {
    create("flutterRelease") {
        extendsFrom(configurations.getByName("releaseImplementation"))
    }
    create("flutterDebug") {
        extendsFrom(configurations.getByName("debugImplementation"))
    }
    create("flutterProfile") {
        extendsFrom(configurations.getByName("debugImplementation"))
    }
}

dependencies {
    "flutterRelease"("io.flutter:flutter_embedding_release:1.0.0-$engineVersion")
    "flutterRelease"("io.flutter:armeabi_v7a_release:1.0.0-$engineVersion")
    "flutterRelease"("io.flutter:arm64_v8a_release:1.0.0-$engineVersion")

    "flutterProfile"("io.flutter:flutter_embedding_profile:1.0.0-$engineVersion")
    "flutterProfile"("io.flutter:armeabi_v7a_profile:1.0.0-$engineVersion")
    "flutterProfile"("io.flutter:arm64_v8a_profile:1.0.0-$engineVersion")

    "flutterDebug"("io.flutter:flutter_embedding_debug:1.0.0-$engineVersion")
    "flutterDebug"("io.flutter:armeabi_v7a_debug:1.0.0-$engineVersion")
    "flutterDebug"("io.flutter:arm64_v8a_debug:1.0.0-$engineVersion")
    "flutterDebug"("io.flutter:x86_debug:1.0.0-$engineVersion")
    "flutterDebug"("io.flutter:x86_64_debug:1.0.0-$engineVersion")
}

tasks.register("resolveDependencies") {
    doLast {
        configurations.forEach { configuration ->
            if (configuration.name.startsWith("flutter")) {
                configuration.resolve()
            }
        }
    }
}

2、进入gradle安装目录下的init.d目录，创建init.gradle文件

groovy 复制代码

allprojects {
    repositories {
        all { ArtifactRepository repo ->
            if (repo instanceof MavenArtifactRepository) {
                def url = repo.url.toString()
                if (url.contains('repo1.maven.org') || 
                    url.contains('jcenter.bintray.com') || 
                    url.contains('google.com')) {
                    project.logger.lifecycle "Repository ${repo.url} replaced by Aliyun"
                    remove repo
                }
            }
        }
        maven { url 'https://maven.aliyun.com/repository/public' }
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }
    }
}

二、修改项目gradle文件配置

1、修改build.gradle.kts文件中的镜像为国内

groovy 复制代码

allprojects {
    repositories {
        maven { url = uri("https://maven.aliyun.com/repository/gradle-plugin") }
        maven { url = uri("https://maven.aliyun.com/repository/google") }
        maven { url = uri("https://maven.aliyun.com/repository/public") }
        google()
        mavenCentral()
    }
}

val newBuildDir: Directory = rootProject.layout.buildDirectory.dir("../../build").get()
rootProject.layout.buildDirectory.value(newBuildDir)

subprojects {
    val newSubprojectBuildDir: Directory = newBuildDir.dir(project.name)
    project.layout.buildDirectory.value(newSubprojectBuildDir)
}
subprojects {
    project.evaluationDependsOn(":app")
}

tasks.register<Delete>("clean") {
    delete(rootProject.layout.buildDirectory)
}

2、修改settings.gradle.kts文件中的镜像为国内

groovy 复制代码

pluginManagement {
    val flutterSdkPath = run {
        val properties = java.util.Properties()
        file("local.properties").inputStream().use { properties.load(it) }
        val flutterSdkPath = properties.getProperty("flutter.sdk")
        require(flutterSdkPath != null) { "flutter.sdk not set in local.properties" }
        flutterSdkPath
    }

    includeBuild("$flutterSdkPath/packages/flutter_tools/gradle")

    repositories {
        maven { url = uri("https://maven.aliyun.com/repository/gradle-plugin") }
        maven { url = uri("https://maven.aliyun.com/repository/google") }
        maven { url = uri("https://maven.aliyun.com/repository/public") }
        gradlePluginPortal()
        google()
        mavenCentral()
    }
}

plugins {
    id("dev.flutter.flutter-plugin-loader") version "1.0.0"
    id("com.android.application") version "8.7.3" apply false
    id("org.jetbrains.kotlin.android") version "2.1.0" apply false
}

include(":app")

3.修改gradle-wrapper.properties中的distributionUrl

ini 复制代码

distributionUrl=https://mirrors.cloud.tencent.com/gradle/gradle-8.12-all.zip
