推荐答案

这是由Windows配置引起的，可能是通过组策略。 native-platform.dll文件是从其中一个JAR文件中提取的，可能放置在用户主目录的文件夹中，如c：\ Users \\\\ USERNAME％\ Local Settings \ Temp。对于恶意软件保护，DLL的加载和从TMP目录执行程序可能被禁用。

This is cause by Windows configuration, probably through group policy. The file native-platform.dll is extracted from one of the JAR files, and probably placed in folder in the user home directory, such as c:\Users\%USERNAME%\Local Settings\Temp. For malware protection, loading of DLL's and execution of programs from TMP directories may be disabled.

我遇到同样症状的问题，我可以解决在某些情况下，通过将TEMP和TMP环境变量设置为指向用户目录之外，如c：\ tmp。这不是一个通用的解决方案，并不适用于Gradle。 Gradle提取DLL的位置可以通过将GRADLE_OPTS设置为指向所需位置来覆盖。这可能适用于你：

I have a problem with the same symptoms, and I have been able to work around it in some cases by setting TEMP and TMP environment variables to point outside the user directory, such as c:\tmp. That has not been a universal solution and did not work for gradle. The location to which Gradle extracts DLL's can be overwritten by setting the GRADLE_OPTS to point to the desired location. This may work for you:

C：\ mkdir C：\ tmp

C:\ mkdir C:\tmp

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

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