Gradle 无法获取 Unity Mediation、Firebase 和 Google Play 服务的依赖项

Question

我无法强制解决这个问题。直到几天前它工作正常。我假设在从 Unity Mediation 安装一个包后，这一切都是问题。之后，我删除了那个包，但这个错误仍然没有解决。

我什至试图再次重新导入所有这些包。尽管如此，问题仍然存在。

Answer 1

1. 在 Unity 编辑器中，打开您的项目并转到“项目设置”>“播放器”>“发布设置”>“自定义主要 Gradle 模板”并确保启用“自定义主要 Gradle 模板”复选框。
2. 然后，转到“项目”选项卡并导航到“资产”>“PlayServicesResolver”>“Android解析器”>“强制解析”。
3. 现在尝试构建项目。 （使用这些设置，Android 依赖项将不再直接包含在项目中）

这将解决所有依赖项。如果您在构建 (Gradel Build) 时遇到问题。转到项目设置 > 播放器 > 发布设置和 select 自定义 Gradle 属性模板复选框。然后 导航到复选框下方的路径并将这两行添加到文件末尾：

android.useAndroidX=true
android.enableJetifier=true

然后进行构建。希望有用。
