I have tried several options  but this one finally solved my problem  I re-imported the project by following these steps in IntelliJ    File -  New -  Project From Existing Repositories Choose your project from  Select File or Directory to Import  In the next screen choose  Import Project From external model   and choose  Maven  In the next step  click the checkbox  Import Maven projects automatically    that solved my problem   Finish up by choosing profiles if necessary   For me re-importing maven projects did not solve the issue for an existing projects

If you have any dependencies in pom xml specific to your organisation than you need to update path of setting xml for your project which is by default set to your user directory in Ubuntu    home user  m2 settings xml -   change it to your apache-maven conf path

If you imported your maven project in IntelliJ and there are errors because of maven imports not getting resolved  it maybe because of the custom maven settings xml you may be using  I tried overriding it in the Intellij default maven settings but it did not help  Finally I had to keep it in    m2 settings xml and then IntelliJ finally honored it

In IntelliJ 12 1 4 I went through Settings -- gt  Maven -- gt  Importing and made sure the following was selected    Import Maven projects automatically Create IDEA modules for aggregator projects Keep source    Exclude build dir    Use Maven output    Generated souces folders   detect automatically  Phase to be      process-resources  Automatically download   sources   amp   documentation  Use Maven3 to import project  VM options for importer  -Xmx512m    This took me from having a lot of unresolved import statements to having everything resolved   I think the key here was using Maven3 to import project     Hopefully this helps

Keep in mind that IntelliJ adds your local Maven installation s classes to its own classpath  so keep it up to date   In my case IntelliJ tried to call method org eclipse aether util ConfigUtils getFloat    This caused a java lang NoSuchMethodError  because my years old Maven version didn t contain this method yet  Due to the exception IntelliJ stopped resolving dependencies   After updating Maven  you have to change the  Maven home directory  setting in  Build  Execution  Deployment  -   Maven   After that you must restart IntelliJ  because the classpath of IntelliJ s JVM won t change while running   It took me some time to solve this problem  as I didn t expect IntelliJ to use the classes of my local Maven installation  I thought it uses it s own bundled JARs  So hopefully this information is helpful for others

It seems to me that solutions to this problem is plenty and all look a bit like magic  For me  invalidation of caches  re-importing or anything else already mentioned was not working  The only thing that helped was  without re-import  go to Maven settings  uncheck automatic importing and re-check it back

Okay I was facing this problem for days  Was trying to import POI library and Simple JSON library  I tried all the proposed answers and solution nothing worked  In the end the solution for my case was quite simple   I just needed to add the following to my module-info java file after putting the dependencies in my POM file     requires poi ooxml   requires poi   requires json simple    so I think because my project was in a package in a module I had to do this to let the system knows that these imported libraries will be used  so simple put the library name after require in your module-info java file   Hope it works for you
