使用NetBeans运行Gradle项目时遭遇java.nio.file.AccessDeniedException异常

按照教程操作，通过CMD执行gradle run可正常将文件上传至Google Drive，但使用NetBeans 13运行同一Gradle项目时，出现java.nio.file.AccessDeniedException错误，无法访问项目下的tokens目录。

已确认信息 #

• NetBeans 13的Gradle插件已正常安装

1. 以管理员身份运行NetBeans #

右键NetBeans快捷方式，选择以管理员身份运行，再执行项目。Windows下IDE可能因权限不足无法修改项目目录内的文件/文件夹。

2. 修改tokens目录权限 #

找到项目下的tokens目录（不存在则手动创建），右键选择属性 -> 安全 -> 编辑，给当前用户添加完全控制权限，应用后重新运行项目。

3. 更换令牌存储目录 #

避免在项目目录内存储令牌，改为用户目录下的路径，比如System.getProperty("user.home") + "/.credentials/drive-tokens"。修改代码中TOKENS_DIRECTORY_PATH的值：

private static final String TOKENS_DIRECTORY_PATH = System.getProperty("user.home") + "/.credentials/drive-tokens";

手动创建该目录并赋予当前用户权限，再重新运行。

4. 绕过权限检查或降级JDK #

Google的FileDataStoreFactory在Windows下会尝试设置目录权限为仅所有者可访问，JDK 17可能存在兼容性问题。可通过自定义DataStoreFactory绕过权限检查，或降级JDK到11版本尝试。
