You can go to Preferences -> Build, Execution, Deployment -> Build Tools -> Maven -> Importing and check the box that says Import Maven projects automatically.

In Mac, you can do Command + Shift + A, then enter the action reimport, then click on Reimport all Maven projects.

IntelliJ Idea not removing (external) libraries – IDEs Support (IntelliJ Platform) | JetBrains
April 21, 2021 - Actual: 4) run 'reload all maven projects' (maven toolwindow) > the dependency is not removed from 'external libraries' and in case of version change the new version is added as library => 2 versions of the same library 5) searching in the project folder it also/still appears in the .iml file under <orderEntry/> The removed versions keep coming back. To fix this I tried: - manually deleting those libraries in IntelliJ: this works until the next 'reload' which load all the versions you ever entered - manually deleting the .iml file: as soon as this file is recreated, the problem returns - manually deleting the .idea folder: solves the problem of the returning bad versions until you change a dependency version or remove the dependency.

Not all Maven dependencies appear in "External libraries" – IDEs Support (IntelliJ Platform) | JetBrains
March 30, 2012 - We have several nested layers of poms, the top level pom was recognised by Intellij but the lower level poms in the subdirectory were not, so I right clicked the lower level pom.xml and chose 'Add as Maven Project' ... I am also having the issue, none of solution above helped me. The only way I could refresh the dependencies was restarting the idea, since I can not develop that way, I found a very ugly workaround which does not force me to restart Idea, every time I want to reload project I go to maven settings and change the maven which the idea uses (I have the maven that came with the IDEA, and a manual installed maven, so I simply replace it each time I want to reload the module)

Force Refresh Of Dependencies – IDEs Support (IntelliJ Platform) | JetBrains
January 13, 2018 - Its a plain old project, no maven, no gradle etc. Things work nicely when i set that directory up in the modules dependency tab. However, if the class files in this dependent directory change, intellij can take an age before it refreshes itself to update and re-read the dependency classes.

IntelliJ not able to resolve classes of external Libraries for Maven projects – IDEs Support (IntelliJ Platform) | JetBrains
February 2, 2016 - 3. External dependencies shows everything, it could be that the dependency is added to some other module and the module that has the problem doesn't have this specific dependency for some reason. Please try to delete .idea directory and .iml files, then reimport the project from Maven. ... Can I consider adding the required libraries for the particular module as dependencies?
