BUILD FAILED in 1m 8s

which have been solved by doting this command from here :

Try the below command from the path where your pom.xml is present,

$ git config --global url."https://".insteadOf git:/
it worked for me.

Which i don't know why this happens. i want to declare you this situation if be useful.

Thanks.
