IntelliJ IDEA, maven project does not automatically import dependencies

Question

I imported a maven project, but idea does not automatically import dependencies.

But I've checked the box for "Import Maven projects automatically".

I tried to delete .idea and .iml and re-import the project.

About idea:

The structure of my project in idea：

Update problem！

I found something wrong with my pom.xml,If I change into other pom.xml, I can import the dependency automatically. But I don't know where the problem is.

Answer 1

Your packaging define is pom, and you have just dependencyManagement not dependency section. These defines is used for parent pom. You may check maven for information about them.

To solve:

Change packaging to jar and remove the dependencyManagement while keep the dependency should let you import your dependencies.

Answer 2

First, make sure to use the latest Intellij Idea version. Current latest version is 2018.1.4. You could use the Jetbrains Toolbox to update automatically.

Second, your pom.xml should be under ~/dev/micro-service and not ~/dev/micro-service/src - read Introduction to the Standard Directory Layout in order to understand how a maven project should look like.
