当我在 Eclipse 中导入 git 项目时会发生这种情况。我尝试了mvn install、mvn package，但它给出了相同的错误。然后我也更新了我的项目，但仍然是同样的问题。怎么解决这个问题？

这是与-e一起使用的:

Maven 似乎无法解析您的“env”属性。检查是否存在配置文件或必须显式激活才能定义“env”属性的内容。在附加配置文件中定义此类属性是常见的做法。

为了从命令行激活配置文件，请使用 -P:

mvn -Pprod install

最后，您可以像这样显式运行 mvn 命令来定义属性:

mvn -Denv=prod install

如果是 Eclipse，则在项目上单击鼠标右键，从菜单中选择“Maven->选择 Maven 配置文件...”，然后选择在构建项目时应激活的所有配置文件。

要检查是否有任何可用的配置文件，请使用:

mvn help:all-profiles
