STS4 in VSCode not Accepting Proxy Settings

[rkralston]

Latest STS4 extension in latest VSCode does not use any proxy settings. I have proxy configured in VSCode with the overrie extensions set. I also have the http(s)_proxy environment vars set. Maven can download from corp repos, but STS fails.

I am on Windows 10 1809

I am using VPN to connect to corp network. No issues with any other system using proxy.

Hmm... what exactly fails in STS4? Is this the Spring Boot extension? How exactly does it fail? Don't think it downloads anything...

[rkralston]

Before it runs, it tries to build the package. When it does, it can't download anything. When I run Maven manually at the command prompt, it builds just fine.

@rkralston If I understand the issue correctly, the Java tooling in VSCode doesn't do the right job when running the maven build under the hood to download the dependences of the project. Is that correct? If so, I would recommend to ask that question or file that issue with the Java tooling for VSCode.

Here is also a specific section about the Java tooling and proxy configs:
https://code.visualstudio.com/docs/java/java-faq#_how-can-i-use-it-behind-a-corporate-proxy

And here is the documentation from the Java support project itself:
https://github.com/redhat-developer/vscode-java/wiki/Using-a-Proxy

If that doesn't help and you are facing an additional issue around proxies, I would recommend to file an issue there.

Hope this helps.

Closing this one due to no further feedback arrived, maybe the previous comment helped. If this is still an issue, please comment and we can re-open the issue.

I am getting following Exception that https://api.spring.io/projects could not be reached.
Direct connection is forbidden on my corporate machine.
Eclipse is configured to use Proxy, but I gues STS4 does not use thise settings. (Thus my comment here)

Hmm... looks like we'd need to incorporate these settings into Boot language server settings. Do you mind moving this into a separate git issue?
