Project Build Error : Non-resolvable parent POM - maven

Question

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:
used maven->Update maven project (no improvement)
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)
Tried executing mvn eclipse:eclipse command. But it failed.
used the command in cmd mvn clean install -U

Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.0.0.RELEASE from/to artie (http://repo.maven.apache.org/maven2/): NullPointerException and 'parent.relativePath' points at no local POM pom.xml

Answer 1

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.

Answer 2

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

Answer 3

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.
