【问题解决】Android Studio Jellyfish新建Kotlin项目后Gradle Sync及Maven下载很慢

创建新项目之后，Gradle Sync和Build都很慢，因为下载Gradle和Maven等工具。

代码默认配置

settings.gradle.kts

pluginManagement {
    repositories {
        google {
            content {
                includeGroupByRegex("com\\.android.*")
                includeGroupByRegex("com\\.google.*")
                includeGroupByRegex("androidx.*")
            }
        }
        mavenCentral()
        gradlePluginPortal()
    }
}

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
    }
}

gradle-wrapper.properties

原本是gradle官网的

#Thu May 23 21:59:57 CST 2024
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-8.6-bin.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

解决方案

1、首先把gradle的地址替换成国内镜像源，会很快下载完gradle

gradle ->wrapper-> gradle-wrapper.properties配置文件

原始：https\://services.gradle.org/distributions/gradle-8.6-bin.zip
替换成 https\://mirrors.aliyun.com/macports/distfiles/gradle/gradle-8.6-bin.zip

#Thu May 23 21:59:57 CST 2024
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
#distributionUrl=https\://services.gradle.org/distributions/gradle-8.6-bin.zip
distributionUrl=https\://mirrors.aliyun.com/macports/distfiles/gradle/gradle-8.6-bin.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

阿里云镜像 Gradle下载地址（新）：macports-distfiles-gradle安装包下载_开源镜像站-阿里云

可以在上述网站复制对应版本的链接，替换到settings.gradle中的distributionUrl。

但还是存在maven很慢的问题，是因为settings.gradle中仓库源配置问题。

2、修改settings.gradle.kts仓库

添加maven在前面

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

Note：修改配置后环境依然不太干净会影响实际效果，可以File -> Invalidate Caches... 清除缓存重启

问题过程记录

软件版本

Android Studio Jellyfish | 2023.3.1

新建Kotlin项目

New Project -> Empty Activity

填写项目信息选择kt语言后Finish，同步项目环境配置。当时 Mininum SDK选了34，因为以为是最高版本用...

Gradle Sync 很慢

同步了好久

两小时都没好

最后还是停掉了，可以看到Maven一直很耗时。

修改配置后依然报错很慢

新增url但注释原本的配置会报错

Plugin [id: 'com.android.application', version: '8.4.0', apply: false] was not found in any of the following sources:

* Exception is:
org.gradle.api.plugins.UnknownPluginException: Plugin [id: 'com.android.application', version: '8.4.0', apply: false] was not found in any of the following sources:

- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Plugin Repositories (could not resolve plugin artifact 'com.android.application:com.android.application.gradle.plugin:8.4.0')
Searched in the following repositories:
maven(https://maven.aliyun.com/repository/central)

然后去掉原本配置注释，还是会用到service.gradle.org下载很慢
