Eclipse (STS) HTTP Proxy Configuration

eclipse proxy spring-tool-suite

I upgraded from Spring Tool Suite (STS) 3.2 to STS 3.3 and it has brought a few issues with it.

When trying to download plugins, I get "Proxy Authentication Required.." errors.

I have my http proxy configured correctly (the same way as 3.2). I have even compared all the .ini files between the versions and cannot find a difference.

As many posts have suggestion, I have also cleared the SOCKS proxy, and even tried to specify in the .ini files that it is not to be used- but again without any luck.

I have tried configuring the HTTPS proxy and playing with the properties in the .ini files for both, restarts, running under different permissions, ect...

Could use some new ideas on this one.

Thanks a lot for reading.

I had the same problem. It turned out that this was caused by two plugins. To allow your STS to connect to the internet via proxy just delete this two plugins:

  • org.apache.httpcomponents.httpcore_4.2.4.v201305222326.jar

  • org.apache.httpcomponents.httpclient_4.2.5.v201305222326.jar

There should be older versions of this plugins so everything should be working fine.
