Question

我导入了一个maven项目，但是idea并没有自动导入依赖项。

但是我已经选中了＃34;自动导入Maven项目的方框＆＃34;。

我尝试删除.idea和.iml并重新导入项目。

关于想法：

IntelliJ IDEA 2018.1.1 (Ultimate Edition)

我的项目结构的想法：

更新问题！

我发现 pom.xml 有问题，如果我更改为其他 pom.xml ，我可以自动导入依赖项。但我不知道问题出在哪里。

Answer 1

首先，请务必使用最新的Intellij Idea版本。目前最新版本是2018.1.4。您可以使用Jetbrains Toolbox自动更新。

其次，您的pom.xml应位于~/dev/micro-service而不是~/dev/micro-service/src - 阅读Introduction to the Standard Directory Layout，以便了解maven项目的外观。

Answer 2

您的packaging定义为pom，而您只有dependencyManagement而非dependency部分。这些定义用于父pom。您可以查看maven以获取有关它们的信息。

要解决：

将packaging更改为jar并删除dependencyManagement，同时保留dependency可让您导入依赖项。

IntelliJ IDEA，maven项目不会自动导入依赖项
