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?

You don't have to reimport manually each time. You can enable auto-import as documented here. Change this in Settings -> Maven -> Import Maven projects automatically.

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

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

Auto-Reload Settings

Then check "Any Changes":

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

List item

  1. Click Delete Existing Project and Import

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.

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.
