Intellij IDEA code completion does not suggest classes coming from maven dependencies

Question

This may sound stupid but here I go (there's no silly question after all, right?): I'm working on a JAVA Maven module with IntelliJ IDEA and the code completion feature works fine suggesting classes from both my module and the JDK.

However, the code completion feature does not seem to be aware of classes coming from Maven dependencies my module depends on.

For instance, my module depends on Maven dependencies such as joda-time. The code completion popup does not suggest classes such as LocalDate.

Here's my code completion configuration:

code-completion-configuration

What am I missing? Thanks in advance.

Can IntelliJ detect `joda-time` in your code (i.e. does your code compile in the IDE)? — Tim Biegeleisen, Apr 18 '15 at 14:53
My whole module does compile. Code completion does work for classes from the SDK, as I mentioned in the question. — kyiu, Apr 18 '15 at 15:04
Please have a look [here](http://stackoverflow.com/questions/23462940/intellij-code-completion-not-working-for-new-java-classes). Possible causes are your POM file or IntelliJ running in power save mode. — Tim Biegeleisen, Apr 18 '15 at 15:06

Found the solution:

Clicked on File > Invalide caches/restart
Chose Invalidate and Restart
After restarting IntelliJ rebuild indexes from scratch and code completion works like a charm.

I am still getting bugs witht the latest intellij (183.5912.21), invalidating caches and restarting sometimes works but not always – Robbie Cronin Mar 08 '19 at 01:51

If it is a Gradle or Maven Project As shown in the picture, you may need to import your project build.gradle file if Gradle or maven bom.xml file if Maven. It will sync your project and may download required files from gradle or maven server.
