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 have summarised what I did for my issue.

1) Delete .m2 folder. 2) Change the apache-maven-3.5.4\conf\settings.xml as follow

  optional
  true
  http
  proxyserver.company.com --> Please change it according to your proxy
  8080 -->Please change it accordingly
  local.net|some.host.com

3) Try again in cmd. It will work.

4) For eclipse, delete the existing maven project and go to

window ->prefernces -> maven -> user settings -> browse -> configure this path apache-maven-3.5.4\conf\settings.xml

5) Delete .m2 folder.

6) Restart the eclipse and try creating new maven project.

These steps worked for me.
