Build was configured to prefer settings repositories over project repositories but repository ‘maven

，但是从gradle版本，和gradle插件版本号在7.0之后，自定义源的方式稍有不同，折腾半天，记录一下。

在之前我们是在build.gradle（project）中去配置：（7.0版本以下都可以用这个方法）

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        google()
        jcenter()
        
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.0'
        
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        maven {
            url "https://jitpack.io"
        }
        maven {
            url "http://dl.bintray.com/lukaville/maven"
        }
        maven {
            url "https://maven.google.com/"
        }
    }
}

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

但是7.0之后有变化
但是在gradle7.0后使用这种方法会报Build was configured to prefer settings repositories over project repositories but repository 'maven的错误，我们将build.gradle（project）恢复到初始状态：
然后到项目的setting.gradle中去配置

pluginManagement {
    repositories {
        gradlePluginPortal()
        google()
        mavenCentral()
    }
}
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
        maven { url 'https://jitpack.io' }
    }
}
rootProject.name = "MyFloatButton"
include ':app'
