Maven 尚未为此生成指定任何目标。

我想让Maven在Docker工作

所以我从她那里提取了图像

但是，当我运行它时：

docker run maven

我得到：

我没有Maven的经验，所以我不明白是什么导致了这个问题

---

Docker容器只安装了Maven，但是它没有运行它，所以我不明白Maven是如何抛出错误的。

你需要在点击

build as Maven

后在目标选项卡中定义

clean install

，或者运行类似于

surefire:test

等等，我不明白。代码中到底应该更改什么？您需要执行以下操作：`docher run maven clean`？检查这是否没有任何问题…什么是

单击构建

？也要避免用“u”代替“you”。这是一个专业网站，强烈反对使用俚语。@GoodbyeStackExchange，答案经过编辑以解决您提出的问题。
