I had a similar problem in spring tool suite sts   THE  m2 repository was not completely downloaded in the local system which is the reason why I was getting this error  So I reinstalled sts and deleted the old  m2 repository from the system and created a new maven project in sts which downloaded the complete  m2 repository  It worked for me

This helped me  I created a new maven project which was working fine in my old workspace  but gave above errors in the new workspace  I had to do the following   - Open old workspace on Eclipse  - open Preferences tab  - Search Maven in filter  - Copy the path for settings xml from User Settings - User Settings  - Switch to new workspace  - Update the preferences - Maven - User Settings - User Settings path  After the build is completed  all errors are resolved

Try the following    Make sure you add M2 HOME variable to your environment variables  It looks like you might have set M2 HOME temporarily in a cmd window and not as a permanent environment variable  Also append M2 HOME to the PATH variable   Go to the m2 folder in your user directory  Example  On Windows  for user bot  the  m2 directory will be under C  Users bot  Look for the settings xml file in this directory and look for the repository url within this file  See if you are able to hit this url from your browser  If not  you probably need to point to a different maven repository or use a proxy   If you are able to hit the repository url from the browser  then check if the repository contains the maven-resource-plugin version 2 6  This can be found by navigating to org apache maven plugins folder in the browser  It s possible that your pom has hard-coded the dependency of the plugin to 2 6 but it is not available in the repository  This can be fixed by changing the depndency version to the one available in the repository
