Android Studio添加外部依赖出错问题解决

最近想要做一个展示图表的app，使用gradle构建时报错2天没有解决，最终在耐心钻研下终于成功运行，先将问题与解决办法总结如下

第一步 下载库文件.zip

MPAndroidChart:v3.1.0下载地址，https://github.com/PhilJay/MPAndroidChart
下载后解压获得MPAndroidChart-master文件夹
在file->new->Import Module->Source directory:C:\Users\ASUS\Desktop\MPAndroidChart-master

第二步 添加依赖后需要修改配置

// 项目级 build.gradle
plugins {
//    alias(libs.plugins.android.application) apply false // 使用版本目录（Version Catalogs）管理插件
    id 'com.android.application' version '7.4.2' apply false
}

// 主应用模块级 build.gradle
plugins {
//    alias(libs.plugins.android.application)  //默认注释掉
    id 'com.android.application' version '7.4.2'  //修改gradle版本为 7.5与7.4.2兼容
}

android {
    namespace 'com.example.ruhe_im_moudeo'
    compileSdk 34

    defaultConfig {
        applicationId "com.example.ruhe_im_moudeo"
        minSdk 26
        targetSdk 34
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}
dependencies {

    implementation libs.appcompat
    implementation libs.material
    implementation libs.activity
    implementation libs.constraintlayout
    testImplementation libs.junit
    androidTestImplementation libs.ext.junit
    androidTestImplementation libs.espresso.core
    implementation project(':MPChartLib') //添加库文件
    implementation project(':MPChartExample')//添加模块文件
}

MPChartExample/build.gradle

//MPChartExample/build.gradle
apply plugin: 'com.android.application'

android {
    compileSdkVersion 34
    defaultConfig {
        applicationId "com.xxmassdeveloper.mpchartexample"
        minSdkVersion 26  //最小版本与主模块同步
        targetSdkVersion 34  //目标版本与主模块同步
        versionCode 57
        versionName '3.1.0'
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation "androidx.appcompat:appcompat:1.0.2"
    implementation 'com.google.android.material:material:1.0.0'
    implementation project(':MPChartLib')
}

MPChartLib/build.gradle

apply plugin: 'com.android.library'
//apply plugin: 'com.github.dcendents.android-maven'//这里会报错，注释掉

group='com.github.philjay'

android {
    namespace 'com.github.philjay'  //新版本需要添加命名
    compileSdkVersion 34
    buildToolsVersion '28.0.3'
    defaultConfig {
//        applicationId "com.github.philjay"//作为库文件不需要id
        minSdkVersion 26  //与主模块同步最小版本
        targetSdkVersion 34  //与主模块同步目标版本
        versionCode 3
        versionName '3.1.0'
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    testOptions {
        unitTests.returnDefaultValues = true // this prevents "not mocked" error
    }
}

dependencies {
    implementation 'androidx.annotation:annotation:1.0.0'
    testImplementation 'junit:junit:4.12'
}

task sourcesJar(type: Jar) {
    from android.sourceSets.main.java.srcDirs
    archiveClassifier = 'sources'  //改为archiveClassifier类
}

task javadoc(type: Javadoc) {
    options.charSet = 'UTF-8'
    failOnError  false
    source = android.sourceSets.main.java.sourceFiles
    classpath += project.files(android.getBootClasspath().join(File.pathSeparator))
}

task javadocJar(type: Jar, dependsOn: javadoc) {
    archiveClassifier = 'javadoc'  //改为archiveClassifier类
    from javadoc.destinationDir
}

artifacts {
    archives sourcesJar
    archives javadocJar
}

修改项目的settings.gradle

pluginManagement {
    repositories {
        google {
            content {
                includeGroupByRegex("com\\.android.*")
                includeGroupByRegex("com\\.google.*")
                includeGroupByRegex("androidx.*")
            }
        }
//        google()
        mavenCentral()
        gradlePluginPortal()
    }
}
dependencyResolutionManagement {
//    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositoriesMode.set(RepositoriesMode.PREFER_SETTINGS) // 更改优先使用 settings 中的仓库
    repositories {
        google()
        mavenCentral()
    }
}

rootProject.name = "ruhe_im_moudeo"
include ':app'
include ':MPChartLib' //添加
include ':MPChartExample'  //添加

修改MPChartExample/AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>

file-> Invalidate Caches ->Invalidate and Restart 等待应用重启，等待重新构建

在activity_main.xml中添加测试
在MainActivity.java中添加引用测试有没有报错
