[maven] How can I make IntelliJ IDEA update my dependencies from Maven?

When I manually add dependencies in the pom.xml of my project, let Maven download the dependencies and let IntelliJ build the module, IntelliJ complains about missing libraries. At the same time Maven can find the dependent JARs and build the project.

How can I tell IntelliJ to use the libs which are downloaded by Maven?

IntelliJ IDEA 2016

Import Maven projects automatically

Approach 1

• File > Settings... > Build, Execution, Deployment > Build Tools > Maven > Importing > check Import Maven projects automatically

  

Approach 2

• press Ctrl + Shift + A > type "Import Maven" > choose "Import Maven projects automatically" and press Enter > check Import Maven projects automatically

Reimport

Approach 1

• In Project view, right click on your project folder > Maven > Reimport

Approach 2

• View > Tools Windows > Maven Projects:

  • right click on your project > Reimport

  or

  • click on the "Reimport All Maven Projects" icon:

    

For some reason IntelliJ (at least in version 2019.1.2) ignores dependencies in local .m2 directory. None of above solutions worked for me. The only thing finally forced IntelliJ to discover local dependencies was:

1. Close project
2. Open project clicking on pom.xml (not on a project directory)
3. Click Open as Project

4. Click Delete Existing Project and Import

Apart from checking 'Import Maven projects automatically', make sure that settings.xml file from File > Settings > Maven > User Settings file exist, If doesn't exist then override and provide your settings.xml file path.

It turns out IntelliJ does not pick up added dependencies from the local Maven repository. We have to tell IntelliJ to reimport the pom.xml.

1. Open the project view in IntelliJ
2. Right click the pom.xml file and select Maven - Reimport
3. If this works for you IntelliJ will add the dependencies to the project
4. Check the if the dependencies you need are added in
   • File - Project Structure - Project Settings - Libraries
   • and File - Project Structure - Modules - Dependencies

in IntelliJ 2020 in the pom.xml view one should be able to apply pom changes by following key combination: CTRG + SHIFT + O.

And as correctly commented before - IntelliJ additionally shows a balloon widget to import changes.

Uncheck

"Work Offline"

in Settings -> Maven ! It worked for me ! :D

File>Settings>Build,Execution,Deployment>Maven> Check : Always update snapshot

That worked for me.

You need to go to: Maven settings -> Auto-Reload Settings

Then check "Any Changes":
