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.

Any way to force a refresh of external libraries on a remote interpreter? – IDEs Support (IntelliJ Platform) | JetBrains
In the status bar (on mine it's in the lower right of the window) you should see Remote Python 3.8.3 (or whatever version you've got) click on it and a list of interpreters will pop up; Select the same interpreter and it will refresh the libraries and skeletons.

Syncing and reloading - JetBrains Guide
October 23, 2024 - We can set IntelliJ IDEA to automatically reload the project after "Any changes" in the build script files, so changes are automatically reloaded. Alternatively, we can have the project automatically reload only after those changes are made by an external system, for example getting updated files from version control.

External Libraries do not update when changing Spring Boot Gradle plugin version – IDEs Support (IntelliJ Platform) | JetBrains
In my Gradle project, I recently updated the version of the Spring Boot Gradle plugin from 2.1.3-RELEASE to 2.5.0 Unfortunately, despite many refresh of the dependencies via the Gradle tab, the dependencies listed in the External Libraries section of the module do not update... Then when I execute some tests, I got weird errors which seem to be linked to the presence of two different versions of AssertJ library. gradlew -q dependencies --configuration testRuntimeClasspath · gives the right information about the AssertJ version (3.19.0) but Intellij is still stuck at 3.11.0

July 6, 2017 - Initial gradle version was 3.3. I have upgraded to 4.0. I still couldn't see the external dependencies importable into Intellij after clean build following cache reset. for instance dependencies{ compile('com.google.code.gson:gson:2.2.4') compile('org.springframework.boot:spring-boot-starter-data-gemfire') } Appending above dependencies to build.gradle. Then after i run ./gradlew build. The build is successful however the External Libraries in Intellij does not display Gradle:com.google.code.gson:2.2.4 or gemstone.gemfire also happened with okhttp3 dependency.

January 12, 2017 - Reload to refresh your session. ... I want to update the Go SDK after I change the project SDK in Project Structure panel. ... The External Libraries tree can be updated immediately after I change project SDK. ... It always displays the same Go SDK no matter how I change the project SDK. I run the plugin from source using Gradle. Additionally, I think go-lang-idea-plugin and intellij-erlang have a similar internal design, but I can easily update the External Libraries tree immediately after I change project SDK with intellij-erlang even I comment all the configurations here which confuses me a lot.

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)

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.

Gradle toggling between 2 missing dependencies on refresh – IDEs Support (IntelliJ Platform) | JetBrains
Builds fail because of ClassNotFoundException on the missing classes from that dependency. Clicking Gradle Refresh again causes that dependency to reappear inside the Project->External Libraries, but now a different dependency is now missing.
