STS unable to find certification

Question

I have downloaded the latest version of spring tool suite (STS 3.6.2), when I tried to import spring getting started content, it return as below error:

Get started Guide SunCertPathBuilderException: unable to find valid certification path to requested target

I have setup the proxy to visit internet, but I don't know how to import certifications in STS. Please help. Thanks.

Answer 1

Had the same issue, so created project from spring initializer https://start.spring.io/ and imported to STS and it loaded all the required .m2 files able to run the application

Answer 2

The default url i had was: https://start.spring.io When i removed the 's' --> http://start.spring.io Then it worked. I guess it is to do with my network settings

Answer 3

If still not getting. Then remove s from https://start.spring.io. It should look like Click here

The above image is referred from spring tool suite official website. When you install a new sts it automatically adds secure connection. Hence we can access to that website currently with out secure only.
