I am working on a spring boot application. The maven version i use is 3.3.9. In settings.xml i have configured the proxy as well. The maven build is getting SUCCESS in command prompt. But when i try to import the project to eclipse am getting project build error.

Methods i have tried to resolve the error:

  1. used maven->Update maven project (no improvement)
  2. In eclipse i have changed the location of local m2 repository as windows->preferences->maven->user settings and pointed it to C:\apache-maven-3.3.9\conf\settings.xml (no improvement)
  3. Tried executing mvn eclipse:eclipse command. But it failed.
  4. used the command in cmd mvn clean install -U

Check your internet connection and ensure that you are able to access http://repo.maven.apache.org/maven2/ with your browser. If yes, check if you need to configure a proxy server. If no, you should contact your internet provider.

see documentation ,for how to configure a proxy server for Maven:

Also delete the .m2 local Directory and run mvn clean install again

UPDATE : Right click on the project --> Maven --> Update project.

  • Proxy is configured and the build is getting success. Getting build error only on importing the project to eclipse. – Shobana VK Nov 26 '18 at 08:13

It worked for me after deleting the .m2 local Directory and then run mvn clean install again.

I have noticed that the windows system user did not have privileges to create the folders .m2 or any other folder in c:\users\user folder. So I elevated the privileges of the system user as admin and it all worked fine.
