当我在 Eclipse 中导入一个 git 项目时会发生这种情况。我尝试了 mvn install、mvn package，但它给出了同样的错误。然后我也更新了我的项目，但仍然是同样的问题。如何解决？

这是 -e:

Maven 似乎无法解析您的“env”属性。检查是否有配置文件或必须明确激活的东西才能定义“env”属性。在附加配置文件中定义此类属性是常见的做法。

为了从命令行使用-P激活配置文件:

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，请在项目上单击 RMB，从菜单中选择“Maven->Select Maven Profiles...”，然后选择在构建项目时应激活的所有配置文件。

要检查是否有可用的配置文件，请使用:

mvn help:all-profiles
