Java IOException使Gradle构建失败

编程问答 2022-08-12

问题描述

当我尝试执行gradle.bat文件或与此相关的任何gradle命令（例如gradle -version）时，出现以下错误。

FAILURE: Build Failed with an exception.

* What went wrong:
java.io.IOException: The filename,directory name,or volume label Syntax is incorrect

版本版本：4.10.2

JDK：“ 1.8.0_261”

操作系统：Windows 10（x64）

可能出了什么问题？

P.S：我也尝试过使用较新的gradle版本（6.6.1）进行同样的操作。它产生了类似的错误。

解决方法

只需在 用户变量 下而不是 系统变量 下添加GRADLE_USER_HOME环境变量即可解决该问题。 / p>
