将所有Maven库批量添加到IntelliJ中的类路径

Question

I've recently cloned a project and run mvn clean install which has installed all the dependencies listed in my the pom.xml . Whenever I open a class I see a lot of import statements that are trying to import a third party class are highlighted with the error cannot resolve symbol Foo . When I Alt+Enter there is an option to add the library to the classpath which completely resolves the issue - for this library:

This would be fine but I have many libraries I need to do this for. Is there a way I can do this in bulk?

EDIT

It's been brought to my attention that I shouldn't have to do this after a mvn clean install if that command completes successfully. As such this is the error I'm getting as the very last part of my logs:

IntelliJ has good Maven support . You should not have to add these dependencies into IntelliJ project manually if you imported the project from Maven pom.xml . Make sure you are selecting Import project from external model option when importing.

Does your project build with mvn clean install ? If not, make sure that it does before changing anything in IntelliJ. Afterwards re-import the project into IntelliJ and double check File | Settings | Build, Execution, Deployment | Build Tools | Maven File | Settings | Build, Execution, Deployment | Build Tools | Maven File | Settings | Build, Execution, Deployment | Build Tools | Maven configuration eg ensure that you are using the same Maven installation in command line and IntelliJ.

Perhaps you have something extra in your settings.xml configuration that makes it work in the command line but fails in IntelliJ when it runs with embedded Maven?
