While I'm trying to install local cloud services using Spring Tool Suite 4 

Spring Tool Suite 4 

Version: 4.3.2.RELEASE
Build Id: 201908130627

and I'm getting

IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 407 authenticationrequired" Unable to tunnel through proxy. Proxy returns "HTTP/1.1 407 authenticationrequired" error messagge.

The same error occurs for if I try to edit Spring boot starters

https://start.spring.io

I've already configured my proxy server under Windows->Prefernces->General ->Network connections -> Active provider to Manual and configured our proxy details for HTTP and HTTPS schemas.

Note: I'm able to install other plug-ins from eclipse market place.

  • Are you able to install local cloud services from CLI? (See https://cloud.spring.io/spring-cloud-cli/) – aboyko Jul 16 '19 at 14:59
  • I'm able to install it directly from spring site, but I'm not able to access spring.io site from STS. For example, if I try to edit Spring boot starters, I'm getting the exception in STS. – SJN Jul 17 '19 at 07:41

To fix this problem, j just add this parameter in file config STS.ini :

-Djdk.http.auth.tunneling.disabledSchemes=""

You must restart Spring-STS after.
