Question

I am working on STS and while creating a new spring-boot project, it shows following error:

 SunCertPathBuilderException: unable to find valid certification          


        

Answer 1

The best thing to do in this case is open https://start.spring.io/ in browser and

and fill in your project name in Artifact field and your project base package in Group field click on

Generate project button

that will download your-project-name.zip file into your downloads folder . now extract this file into your sts workspace or anywhere you like .

now import the project in STS as Existing maven project

You are done
