当我尝试使用时收到此异常DateUtils.addMinutes()：

我的代码正在调用DateUtils.addminutes()向变量添加 1 分钟，date如下所示：

Date target = DateUtils.addminutes(date, 1);

我对我的 Gradle 文件进行了正确的依赖：

implementation 'org.apache.commons:commons-lang3:3.11'

我对此错误进行了很多研究，但其他帖子中提到的解决方案都没有解决我的问题。我该如何解决？

将您的成绩文件更改为：

implementation 'org.apache.commons:commons-lang3:3.6'

然后你可以在你的类中使用这个导入：

import org.apache.commons.lang3.StringUtils;
