这是由 Windows 配置引起的，可能是通过组策略引起的。文件 native-platform.dll 是从其中一个 JAR 文件中提取的，可能位于用户主目录的文件夹中，例如 c:\Users\%USERNAME%\Local Settings\Temp。为了保护恶意软件，可以禁用从 TMP 目录加载 DLL 和执行程序。

我遇到了具有相同症状的问题，在某些情况下，我已经能够通过将 TEMP 和 TMP 环境变量设置为指向用户目录之外(例如 c:\tmp)来解决该问题。这不是一个通用的解决方案，也不适用于 gradle。可以通过将 GRADLE_OPTS 设置为指向所需位置来覆盖 Gradle 提取 DLL 的位置。这可能对您有用:

C:\mkdir C:\tmp

C:\set GRADLE_OPTS="-Dorg.gradle.native.dir=/tmp"
