Unity2019.4.4版本安卓打包 配置离线jdk、androidsdk和Gradle

一、安装unity

第二步jdk和第三步sdk其实下载unity的时候可以自行安装（unity2019版本之上才有这个功能）

但是这里我出现了问题！！！
网上查阅了好多办法，卸载重装unityHub也不行，所以只能乖乖的自己网上下载jdk和sdk

如果出现没有添加模块这种问题，将Unity卸载从UnityHub中重新下载就好了

二、安装jdk，jre （具体安装方法网上好多，这里就不多说了）

下载jdk时一定要对应好unity中所需要的版本，版本不对应打包容易出错找到文件夹

三、下载安装AndroidSDK 下载地址

四、配置环境 传送门
这里要注意如果是从unity的安装模块中下载的jdk和sdk得话，下载的路径可以从unity中找到

四、配置Gradle
一般经历以上步骤可以打包成功的话，那你是幸运的。如果不行那就自己手动配置

找到baseProjectTemplate.gradle文件 ，文件夹路径（unity下载安装路径下）：D:\Unity3D\2019.4.4f1\Editor\Data\PlaybackEngines\AndroidPlayer\Tools\GradleTemplates
使用记事本打开找到这句话

classpath ‘com.android.tools.build:gradle:3.4.0’

其中3.4.0就是unity要使用的插件版本 插件版本对应网址

根据表中显示我们需要下载5.1.1版本Gradel Gradle下载地址
版本好多，我们选择后缀名为all并且文件最大的下载

在unity中设置对应路径

有时候gradle还是需要下载一些东西，这时候我们配置阿里云库下载，打开baseProjectTemplate.gradle文件（上面讲如何找到Gradle对应版本，该文件路径有讲过），
在buildscript和repositories 添加这四句话

        maven {
    
     url 'https://maven.aliyun.com/repository/google' }
        maven {
    
     url 'https://maven.aliyun.com/repository/gradle-plugin' }
        maven {
    
     url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        maven {
    
     url 'https://maven.aliyun.com/repository/jcenter'}

添加前的样子

allprojects {
    
    
    buildscript {
    
    
        repositories {
    
    **ARTIFACTORYREPOSITORY**
            google()
            jcenter()
        }

        dependencies {
    
    
            // If you are changing the Android Gradle Plugin version, make sure it is compatible with the Gradle version preinstalled with Unity
            // See which Gradle version is preinstalled with Unity here https://docs.unity3d.com/Manual/android-gradle-overview.html
            // See official Gradle and Android Gradle Plugin compatibility table here https://developer.android.com/studio/releases/gradle-plugin#updating-gradle
            // To specify a custom Gradle version in Unity, go do "Preferences > External Tools", uncheck "Gradle Installed with Unity (recommended)" and specify a path to a custom Gradle version
            classpath 'com.android.tools.build:gradle:3.4.0'
            **BUILD_SCRIPT_DEPS**
        }
    }

    repositories {
    
    **ARTIFACTORYREPOSITORY**
        google()
        jcenter()
        flatDir {
    
    
            dirs "${project(':unityLibrary').projectDir}/libs"
        }
    }
}

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

添加后的样子

allprojects {
    
    
    buildscript {
    
    
        repositories {

        maven {

        maven {
    
     url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        maven {
    
     url 'https://maven.aliyun.com/repository/jcenter'}

        }

        dependencies {
    
    
            // If you are changing the Android Gradle Plugin version, make sure it is compatible with the Gradle version preinstalled with Unity

            classpath 'com.android.tools.build:gradle:3.4.0'
            **BUILD_SCRIPT_DEPS**
        }
    }

    repositories {
    
    **ARTIFACTORYREPOSITORY**
        //google()
        //jcenter()
        maven {
    
     url 'https://maven.aliyun.com/repository/google' }
        maven {
    
     url 'https://maven.aliyun.com/repository/gradle-plugin' }
        maven {
    
     url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        maven {
    
     url 'https://maven.aliyun.com/repository/jcenter'}
        flatDir {
    
    
            dirs "${project(':unityLibrary').projectDir}/libs"
        }
    }
}

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

这时候小伙伴就可以打包啦。
