Importing a Maven project (Android) with IntelliJ IDEA - maven

Question

If I am using an IDE with Maven integration (IntelliJ IDEA) to import a Maven project (Android), do I still need to run mvn install on the command line to build the project? Or should that all be done by IntelliJ during the project import wizard?
Edit: My issue is that after importing the project into IntelliJ, when I open up my libraries, many of the Maven libraries are linked to wrong sources and javadocs. The folder they are getting the sources and javadocs does exist, but the specific javadoc.jar or sources.jar files referenced do not exist in that folder.
So I'm thinking I did something wrong with my Maven import - I only used the IntelliJ wizard to do it. Oddly the project still compiles and runs fine, the only 'symptom' of this problem is the empty javadocs.
Edit (9 Nov): I tried the method suggested by #JJF and while it does download the missing javadocs and source files, it adds on a '.lastUpdated' suffix to them. Why does that happen?
Also, I manually renamed the javadocs and while that clears things up in the Libraries window, when I go back to my project my inline documentation (mouse hover) still brings up empty documentation (this was the problem that initially led me to this question, I created a different thread for it here). Maybe I might be doing something wrong in my SDK Documentation Paths instead?
Running the process described by #Nick78 produces the errors below:

Answer 1

From the command line run
mvn dependency:sources
mvn dependency:resolve -Dclassifier=javadoc
That will download any missing sources and Javadocs. See Get source JARs from Maven repository
Also WRT to building your project with IntelliJ vs running mvn install: IntelliJ will compile your source files whenever you go to run or debug your app. You don't need to run maven to get your sources to compile. If you want to say package or install your project from within IntelliJ then go to the Maven Projects tool window and expand either the Life Cycle node or the Plugins node and you can run Maven goals by double clicking whatever goal you're interested in running.
If you right click on one of the goals you can create a run configuration for that goal that you can run from the run configurations drop down.

Answer 2

first of all be sure that in the Settings
(Top menu > File > Settings > Build, Execution, Deployment > Build Tools > Maven) IntelliJ is pointing to the same Maven Repository as defined in your Maven Installation defined in M2_HOME. That's usually (in Windows) C:\Users\Username\.m2\repository. Then in the console go to the directory where your pom.xml is located and type in: mvn idea:idea (that will create or recreate your IntelliJ project files). In IntelliJ be sure that under Top menu > View > Tool Buttons is checked. Somewhere at the border of the IntelliJ Window there is a button called Maven Projects click it. In the opened dialog click the green + and add your pom.xml. After that click the reimport button (blue pointer circle) on the top left of the maven dialog. Then in the same dialog expand your project > Lifecycle. Hold ctrl and select clean and install. Click the blue circle with the lighning (skip tests) and after that the play button. Maybe do a reimport (blue pointer circle) again.
