VS Code behind a proxy

VS Code extensions can be difficult to use behind a proxy.  

To point CodeScan at the correct proxy, all it takes is a single line in the settings.json file.

"codescan.ls.vmargs": "-Dhttp.proxyHost=your.proxy.host -Dhttp.proxyPort=3333 -Dhttps.proxyHost=your.proxy.host -Dhttps.proxyPort=3333"

Troubleshooting

Some useful debugging information is available under the Output window under the ‘CodeScan’ tab.

CodeScan should automatically find the JRE installed on your computer. If you are having trouble you can specify the path using sonarlint.ls.javaHome variable in your VS Code Settings.

You can check for any serious errors by going to Help > Toggle Developer Tools to bring up the console.
