Unity 之 解决2019之后的版本打apk卡到Building Gradle project问题

• 一，遇到问题
• 二，分析问题
• 三，解决问题
• • 方法一：修改配置文件
  • 方法二：修改Preferences属性

一，遇到问题

安装环境：安装android Build Support;【需要将下拉菜单的两项一并安装】

问题：
Unity2019 版本打包apk，卡到Building Gradle project这一直不动，长时间等待后打包失败

---

二，分析问题

失败原因：是在下载的对应版本Gradle时，需要访问外网下载速度慢或者网络不稳定导致失败

---

三，解决问题

方法一：修改配置文件

1，找到Untiy安装目录下的AndroidPlayer\\Tools\\GradleTemplates文件夹下的 baseProjectTemplate.gradle 文件

参考我的目录：
D:\\Program Files\\Unity\\2019.4.19f1c1\\Editor\\Data\\PlaybackEngines\\AndroidPlayer\\Tools\\GradleTemplates

// GENERATED BY UNITY. REMOVE THIS COMMENT TO PREVENT OVERWRITING WHEN EXPORTING AGAIN

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

修改为：

// GENERATED BY UNITY. REMOVE THIS COMMENT TO PREVENT OVERWRITING WHEN EXPORTING AGAIN

allprojects 
    buildscript 
        repositories **ARTIFACTORYREPOSITORY**
            //google()
            //jcenter()
           maven url 'http://maven.aliyun.com/repository/google'           
           maven url 'http://maven.aliyun.com/repository/gradle-plugin'
           maven url 'http://maven.aliyun.com/nexus/content/groups/public/'
           maven url 'http://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
            // 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()
        maven url 'http://maven.aliyun.com/repository/google'           
        maven url 'http://maven.aliyun.com/repository/gradle-plugin'
        maven url 'http://maven.aliyun.com/nexus/content/groups/public/'
        maven url 'http://maven.aliyun.com/repository/jcenter'

        flatDir 
            dirs "$project(':unityLibrary').projectDir/libs"
        
    


task clean(type: Delete) 
    delete rootProject.buildDir

然后重新打包即可。

方法二：修改Preferences属性

在官网上提前下载好需要版本gradle：https://gradle.org/releases/
然后在Preferences面板上，将Gradle Installed…选项前面√取消勾选，然后点击“Browse”，找到自己下载好的gradle，然后重新打包就可以了。
