Unity中Win32Exception报错：无法找到gradlew.bat文件求助

环境信息 #

• 操作系统：Windows 11（最新稳定版）
• 受影响Unity版本：
  • 2021.3.24f1
  • 2020.3.47f1
  • 2022.2.18f1

问题核心 #

Gradle仅生成了gradlew脚本，未生成Windows平台必需的gradlew.bat批处理文件，导致Unity的PlayServicesResolver执行时触发文件找不到的错误，怀疑与WSL或UNIX命令模拟工具（如Git Bash）的环境干扰有关。

已尝试无效操作 #

• 配置自定义SDK、NDK、JDK
• 使用scoop安装的Gradle替代默认版本
• 反复重装卸载相关组件

可行解决方案 #

1. 手动生成gradlew.bat #

进入缺失文件的目录（D:\CodingHub\Unity\TEST\Temp\PlayServicesResolverGradle），打开命令提示符执行：

gradle wrapper --gradle-version <对应Unity的Gradle版本>

版本号可在Unity编辑器的Project Settings > Player > Android > Publishing Settings > Build > Gradle Version中获取。执行完成后重试构建。

2. 调整环境变量优先级 #

WSL或UNIX模拟工具的路径可能抢占了Windows原生命令的优先级，导致Gradle生成UNIX脚本：

• 打开系统环境变量设置，找到PATH变量
• 将C:\Windows\System32移至PATH列表最顶端
• 重启Unity后重试

3. 强制Gradle生成Windows脚本 #

在项目的Assets/Plugins/Android/gradle.properties文件中添加以下配置（文件不存在则手动创建）：

org.gradle.wrapper.windows=true

保存后重新触发PlayServicesResolver的依赖下载流程。

4. 清理Unity缓存文件 #

关闭Unity编辑器，删除项目根目录下的Temp和Library文件夹，重新打开项目等待资源导入完成后，再执行相关操作。
