There is also one useful setting that tells IntelliJ to check for new versions of dependencies even if the version numbers didn t change  We had a local maven repository and a snapshot project that was updated a few times but the version numbers stood the same  The problem was that IntelliJ Maven didn t update this project because of the fixed version number   To enable checking for a changed dependency although the version number didn t change go to the  Maven Projects  tab  select  Maven settings  and there activate  Always update snapshots

I had a problem where IntelliJ was unable to compile classes  claiming that dependencies between projects were missing  Reimporting the project as suggested in the answers of this question didn t solve the problem  The solution for me  was    remove all projects  project tab   right click on the root folder   maven   remove projects   close the editor  compile all projects with maven on the command line  open the editor on the same project  add the projects to maven again  maven tab   add maven projects  green      choose the root pom     WARNING  on some projects  you might have to increment max memory for maven import  maven settings on maven tab   Importing   VM options for importer

If you work in IntelliJ  there are four independent ways to refresh maven repositories  Each of them refreshes another local repository on your computer or refreshes them differently  1  mvn -U clean install 2  Ctrl Shift A - Reimport 3  Round arrows in the Maven window  4  Ctrl Alt S   go to Build  Execution  Deployment   Build Tools   Maven   Repositories -choose rep - update  What is interesting  it is often said  that the last refresh is equal to the round arrows in the Maven window  But  according to my experience  they are absolutely different  The proof  Our large project fails the last refresh  but exists and runs happily without it  And double round arrows run OK on it  Each of these four can help you with your problems or and find problems of its own  For example  for running our real-life project only the first is necessary  but for testing in IntelliJ we also need 2 and 3  Surely  somebody needs 4  too   Why else IntelliJ has it
