IntelliJ not loading transitive dependency in maven project

I've made a small library, lets call it lib. It dependends on another library, sublib which is available in Maven central:

lib/pom.xml:

<dependencies>
    <dependency>
        <groupId>3rdparty</groupId>
        <artifactId>sublib</artifactId>
        <version>x</version>
    </dependency>
</dependencies>

Now I'm trying to use lib in my project proj. I've set it as a dependency:

proj/pom.xml:

<dependencies>
    <dependency>
        <groupId>mynamespace</groupId>
        <artifactId>lib</artifactId>
        <version>y</version>
    </dependency>
</dependencies>

When I run mvn exec:java -D exec.mainClass=mynamespace.proj.Main the program runs fine. However if I run it from IntelliJ, I get the following error:

java.lang.NoClassDefFoundError: 3rdparty/SomeSubLibClass
    at mynamespace.SomeLibClass.method(SomeLibClass.java:100)

This seems to indicate that IntelliJ does not load the transitive sublib dependency. How can I fix this?

I had a similar problem. The below command resolved the problem. It downloaded all the dependency jars into my IDEA project.

mvn -U idea:idea

What worked for me was changing from using maven (Intellij) version and using my latest version that was installed on my machine previously.

You can manually right click on the pom.xml file in the file tree and select maven > reimport.

Sometimes you'll see a popup saying "Maven projects need to be imported"; you should select Enable Auto-Import.

Maven auto import popup

This option can be found in Preferences > Maven > Importing > [x] Import Maven projects automatically (and is unchecked by default):
