Could not calculate build plan: Plugin org.apache.maven.plugins:maven-jar-plugin:2.3.2 or one of its dependencies could not be resolved

Question

I got the following error message when I tried to create a Maven project in eclipse. Many have posted about proxies in settings.xml file and also flush the .m2 folder forcin

Answer 1

I also had the same problem. I used next way:

1.Added settings.xml file (~/.m2/settings.xml) with next content

   
      true
      http
      qq-proxya
      8080
      user
      passw
      www.google.com|*.example.com
    
  

3. Using cmd go to folder with my project and wrote mvn clean and after that mvn install !

4. After that updated project in the Eclipse(Alt + F5) or right click on project -> Maven -> Update project

P.S. after that, when I add new dependency to my project I have to compile project using cmd(mvn compile). Because if I do it using eclipse plugin, I get error connecting with proxy connection.
