Today I had this same problem with another jar  I tried multiple things people said on Stackoverflow  but nothing worked  Eventually I did this    Close eclipse and any project-app that is running  Delete the  m2 folder  Users --   your username  --   m2   It s an invisible folder  make sure you are able to view invisible folders  Restarted Eclipse  I guess it works in other IDE too  and updated my project     Now it works again for me  Perhaps this solves the problem for someone else too

I m a little late to the party but I ll give my two cents   I just resolved this issue after spending longer than I d like on it   The above solutions didn t work for me and here s why   there was a network issue when maven was downloading the required repositories so I actually didn t have the right jars  adding a -U to a maven clean install went and got them for me   So if the above solutions aren t working try this    Right click on your project -  Choose Run as -  5 Maven build    In the Goals field type  clean install -U  and select Run After that completes right click on your project again and choose Maven -  Update Project and click ok    Hope it works for you

So I get you are using Eclipse with the M2E plugin  Try to update your Maven configuration   In the Project Explorer  right-click on the project  Maven -  Update project   If the problem still remains  try to clean your project  right-click on your pom xml  Run as -  Maven build  the second one   Enter  clean package  in the Goals fields  Check the Skip Tests box  Click on the Run button   Edit  For your new problem  you need to add Spring MVC to your pom xml  Add something like the following    lt dependency gt       lt groupId gt org springframework lt  groupId gt       lt artifactId gt spring-webmvc lt  artifactId gt       lt version gt 4 0 0 RELEASE lt  version gt   lt  dependency gt    Maybe you have to change the version to match the version of your Spring framework  Take a look here   http   mvnrepository com artifact org springframework spring-webmvc

I got the same problem and this is how i solved      Right click your Spring MVC project  choose Run As -  Maven install  Observe the output console to see the installation progress  After the installation is finished  you can continue to the next step         Right click your Spring MVC project  choose Maven -  Update Project       Choose your project and click OK  Wait until update process is finished  The error still yet  then do Project- Clean and then be sure you have selected our project directory and then do the follow Project- Build

Although it s too late   But here is my experience     Whenever you get your maven project from a source controller or just copying your project from one machine to another   you need to update the dependencies     For this Right-click on Project on project explorer - gt  Maven - gt  Update Project   Please consider checking the  Force update of snapshot releases  checkbox   If you have not your dependencies in m2 repository then you need internet connection to get from the remote maven repository   In case you have get from the source controller and you have not any unit test   It s probably your test folder does not include in the source controller in the first place   so you don t have those in the new repository so you need to create those folders manually   I have had both these cases
