Maven版本：

Apache Maven 3.8.1(Non-Canonical_2021-04-26T21:52:54z_root)Maven Home://opt/Maven Java版本:11.0.11，供应商：Oracle Corporation,运行时：/usr/lib/jvm/java-11-OpenJDK默认区域设置:en_US，平台编码:UTF-8操作系统名称：“Linux”，版本：“5.12.4-arch1-2”，arch：“AMD64”，家族：“UNIX”

OS版本：Arch Linux Maven应该包含从Maven3.7开始的包装器脚本，这应该不是问题，因为我使用的是Maven3.8，但是版本4的错误消息让我感到困惑，我不知道在哪里寻找答案。

有时答案就在眼前，但疲倦的眼睛会让我们失明：D

正如@jfabianmeier所说，没有Maven3.7，从Maven4.0开始就包含了Maven包装器脚本
