Maven plugins can not be found in IntelliJ

Question

After updating IntelliJ from version 12 to 13, the following Maven-related plugins cannot be resolved:

org.apache.maven.plugins:maven-clean-plugin:2.4.1
org.a         


        

Answer 1

You can add them as dependencies:

    
        org.apache.maven.plugins
        maven-clean-plugin
        2.4.1
    

Intellij will resolve them. After successfull import dependencies, you can clean them.
