Gradle 无法获取依赖项 |解析失败-in Unity3d

Question

当我尝试使用 Unity 构建和运行我的游戏时出现此错误。我还从 here 导入了 GooglePlayServices/ads，还有最新的 android sdk 和 jdk-8u144。

这是错误日志：

Gradle failed to fetch dependencies

Answer 1

将 JAVA_HOME 添加到我的环境变量中它是 C:\

Answer 2

play-services-ads.aar

复制到

/Assets/Plugins/Android

。我必须从 sdk 文件夹中手动复制它：sdk\extras\google\m2repository\com\google\android\gms\play-services-ads

我的

/Assets/Plugins/Android

文件夹。

Answer 3

或

-右键单击“我的电脑”并转到属性。

-转到“高级”选项卡

-点击环境变量按钮

-在系统变量下找到JAVA_HOME变量

-将值更改为该文件实际存在的位置。 （对我来说是 C:\Program Files\Java\jdk-10）

-重启Unity

Answer 4

并将地址粘贴到 JAVA_HOME 变量值中。

然后我重新启动我的系统，它获取了所有的 android 依赖项并开始工作。

如果它没有开始自行获取，您可以强制解析 android dependencies.Assets->ExternalDependencyManager->AndroidResolver->force Resolve.
