How to configure Spring facet in IntelliJ IDEA

Question

I\'m new to Intellij 14.0 . I was using Netbeans, but my colleagues told me to shift to intellij and so I did.

I need to run the same project that I ran on netbeans

Answer 1

Go to File/Project Structure/Modules, click the green plus icon, select Spring from the dropdown and select your module in the next dialog.

Then click the green plus in the right pane, click plus and select your Spring configuration files and classes and click OK.

Also take a look at IntelliJ Help for Spring Facet.

Answer 2

Just ran into this issue out of the blue today—my build was working last night, and this morning it stopped working—so I figured I'd post my solution using IntelliJIDE CE 2019.1.

Solution

Step 0: Update IntelliJ

Menu: IntelliJIDE > Check for Updates (Mac OSX) 

Step 1: Clean out Maven repo and re-download dependencies to ensure that the sources are not corrupt. This will take 5+min.

$ cd [project_directory]
$ mvn dependency:purge-local-repository

Step 2: Preform a clean install.

$ mvn clean install

Step 3: Update IntelliJIDE's Repository Indexes:

1. Open IntelliJ Settings/Preferences
2. Build, Execution, Deployment > Build Tools > Maven > Repositories
3. Select repositories one by one (by clicking on the table row) and click the update button. Specifically, do it for https://repo.mave.apache.org/maven2. The download is ±700mb so it will take a while. (10+min)
