java - 编译 Unity Android 应用程序 (Gradle) 时出错

Question

我在使用 Unity 编译我的 android 应用程序时遇到了问题，令人惊讶的是它在几周前可以工作，但在编译时突然出现以下错误：

C:/Program Files/Unity/Hub/Editor/2019.4.20f1/Editor/Data/PlaybackEngines/AndroidPlayer\OpenJDK\bin\java.exe -classpath "C:\Gradle\gradle-6.7.1\lib\gradle-launcher-6.7.1.jar" org.gradle.launcher.GradleMain "-Dorg.gradle.jvmargs=-Xmx4096m" "assembleDebug"

stderr[

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine the dependencies of task ':launcher:compileDebugJavaWithJavac'.
> Installed Build Tools revision 31.0.0 is corrupted. Remove and install again using the SDK Manager.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

我正在使用 Unity 2019.4 和 Gradle 6.7.1，因为它们是在 Unity 中使用 Google ARCore 库时问题最少的版本。但是，据我所知，没有触及任何东西，它不再编译我。有任何想法吗？
