I am creating simple spring boot web application I am using the project generated by spring Initializer

I have set my JDK and maven in the path Also done setting for JAVA_HOME

While running the application getting following error

Non-resolvable parent POM: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:1.5.3.RELEASE from/to central (http://repo.maven.apache.org/maven2): This is usually a temporary error during hostname resolution and means that the local server did not receive a response from an authoritative server (repo.maven.apache.org) and 'parent.relativePath' points at no local POM @ line 14, column 10 -> [Help 2]

following is my POM in the project

Incase you're working for an organisation and need VPN to work. You must connect to VPN before downloading the dependencies. This is what resolved my issue.

In my case, I was using wrong JDK version (1.7) and changing it to (1.8) worked.

For me what worked was that I downloaded the cacerts file provided in the same repository and stored that in the JAVA_HOME/jre/lib/security folder and then I right clicked the Project in the Package Explorer view of Eclipse, Project -> Maven -> Update Project (Alt+F5), and after that it started downloading the dependencies, from the various repos which were unreachable earlier, and later the problem got resolved.

I changed jdk 1.7 to jdk 1.8 and It worked and Don't forget also update your environment variables.

i have already answered it here. try deleting the dependencies in .m2 and update and clean.

and also check the settings.xml is properly configured in window-->preferences-->maven-->User Settings.

For me it work by changing option settings of Netbeans. Tools > Options > Team > Maven > Maven Home

Update by downloading maven manually from original website check maven by using mvn -v. extra inst.(http://maven.apache.org/install.html)

Once Maven is installed, add the maven directory to Maven Home:

Tools > Options > Team > Maven > Maven Home
