How to fix ''Gradle Build Failed'' on Unity?

Question

我正在尝试构建我的 android 应用程序一段时间，但似乎找不到解决此问题的任何方法：

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

控制台详情在这里：

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

我已经尝试过 youtube 和其他论坛上的所有教程，但欢迎大家提供帮助，谢谢！

在尝试 Jaimin 的解决方案后，现在正在发生这种情况：

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.

这里是自定义 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。要从您的

gradle.properties

文件中删除它，您必须转到Project Settings>Player>Android（选项卡）>Other Settings>并检查Custom Gradle Properties Template。

之后，一个

gradleTemplate.properties

文件生成在：

Assets/Plugins/Android/gradleTemplate.properties

在此文件中，删除行

android.enableR8

，或将其注释掉，现在进行新的构建。

这个技巧应该有用。

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。

Answer 2

安装新版Unity，就可以了

可以用Unity 2020.3.33f1版本，我用的就是这个，很好用

记得设置Preferences：Unity默认JDK、Gradle、NDK

Answer 3

我在很多地方都看到了，这个问题真的很痛苦。就我而言，我的问题是我的 csproj 中没有我的旧 CSharp 界面不正确，所以我在 Visual Studio 中看不到。

由于Unity不关心csproj，它在编译时使用它。我刚刚注意到，因为控制台窗口中显示了一个不存在的 java 问题（由于 Android，CSharp 被转换为 Java，因此 Graddle 引发了这个问题）。

尝试在你的 CSharp 程序中找到一些没有出现在 Visual Studio 的解决方案资源管理器中的类，并删除或修复它。

另外，我遵循了 Jaimin 上面指出的修复方法。它对我不起作用，但我就这样离开了。它更有意义。

Answer 4

试试这个 对于 Windows 前往地点

“C:\Program Files\Unity\Hub\Editor�1.1.24f1\Editor\Data\PlaybackEngines\AndroidPlayer\SDK uild-tools .0.0”

找到一个名为 d8.bat 的文件。这是一个 Windows 批处理文件。

将 d8.bat 重命名为 dx.bat.

在文件夹 lib 中（“C:\ProgramFiles\Unity\Hub\Editor�1.1.24f1\Editor\Data\PlaybackEngines\AndroidPlayer\SDK uild-tools .0.0\lib”）

将 d8.jar 重命名为 dx.jar 请记住 AppData 是一个隐藏文件夹。打开隐藏项以查看 AppData 文件夹。

现在运行你的项目...
