Does not properly use proxy settings

[arnauldvm]

I found out that the extension is using the http_proxy environment variable,
even though there is an "http.proxy" setting defined in VS Code.

If, for some reason, I want VS Code to use a different proxy, it gives unexpected behavior for PlantUML.

Please update and help me test, does it works good:

1. if you have http.proxy configured
2. if you have environment variable configured (no http.proxy setting)

I cannot test because I don't have a http proxy. Thanks for the help.

1. if I have http.proxy configured (and no environment variable): no
2. yes

I have also a problem with using this extension behind the proxy. When I try to include an external puml like this:
!includeurl https://raw.githubusercontent.com/awslabs/aws-icons-for-plantuml/master/dist/AWSCommon.puml
the following error appears:

Both http_proxy and https_proxy are set in as environment variables. Setting http.proxy option didn't help either.

I fixed the same issue by setting the proxy settings using plantuml.commandArgs.

• Open VS Code
• Go to File => Preferences => Settings
• In the search box, enter settings.json
• Then click on "Edit settings.json"
• Enter the following config:

"plantuml.commandArgs": [
       "-Dhttp.proxyHost=your-proxy.com,
       "-Dhttp.proxyPort=your-proxy-port",
       "-Dhttps.proxyHost=your-proxy.com",
       "-Dhttps.proxyPort=your-proxy-port"
   ]

@Thialala, Thanks for the feedback.

@zllvm, @Thialala gives the right solution to your case.

@arnauldvm If yours is the same use case, http.proxy won't help, because it cannot control the behavior of java or plantuml.jar.

I'll test this.
