如何修复 Unity 上的“Gradle Build Failed”？

Question

我正在尝试构建我的 Android 应用程序一段时间，但似乎找不到此问题的任何解决方案： Image

Unity版本：Unity 2020.3.21f1（64位） 使用的JDK、SDK、NDK和Gradle都是Unity推荐的（已经尝试使用其他的）。

控制台详细信息在这里：

Configure project :launcher
WARNING: The option setting 'android.enableR8=false' is deprecated.
It will be removed in version 5.0 of the Android Gradle plugin.
You will no longer be able to disable R8

我已经尝试了 youtube 和其他论坛上的所有教程，但欢迎您提供任何帮助，谢谢！

编辑1：

在尝试 Jaimin 的解决方案后，现在发生了这种情况：

Assets/Plugins/Android\gradleTemplate.properties file is using a deprecated way of controlling which tool should be used to do the minification. To fix this, remove "useProguard" entries yourself. If not fixed, your build can fail.

以下是自定义 Gradle 属性模板文件的编码方式：

org.gradle.jvmargs=-Xmx**JVM_HEAP_SIZE**M
org.gradle.parallel=true
unityStreamingAssets=.unity3d**STREAMING_ASSETS**
**ADDITIONAL_PROPERTIES**

Answer 1

这是因为android.enableR8已被弃用。要将其从gradle.properties文件中删除，您必须转到“项目设置” > “播放器” > “Android ”（选项卡）> “发布设置” > “自定义 Gradle 属性模板”，选中此项。

之后，gradleTemplate.properties会生成一个文件：

Assets/Plugins/Android/gradleTemplate.properties

在此文件中，删除行android.enableR8，或将其注释掉，然后进行新的构建。

这个技巧应该有效。

或者，导出为 Android 项目，然后在 Android Studio 中更改它。在 Android Studio 中，您可以更好地控制这些事情。
