IntelliJ cannot resolve jsDependency when connected to corporate VPN

When I'm connected to my company's VPN, IntelliJ is unable to resolve certain jsDependencies.

I have set proxy settings in IntelliJ to point to my corporate proxy server, but this seems to make no difference.

If I disconnect from the VPN, then everything builds fine...

The sbt.last.log file complains:

[error] Server access Error: Connection refused url=https://repo1.maven.org/maven2/org/webjars/jquery/2.1.3/jquery-2.1.3.pom

If this is a problem with my company's proxy server, then I'm not sure why putting the Maven URL into my browser (when connected to the VPN) displays the POM file without any problems.

Also, the path name to the Ivy2 cache shown in sbt.last.log does not match the actual path to the cache on disk. It should be ~/.ivy2/cache.

Any ideas?

Thanks

Solution

It was the VM parameter settings in IntelliJ.

Preferences -> Build, Execution and Deployment -> SBT.

Needed to add:

-Dhttp.proxyHost=hostname
-Dhttp.proxyPort=8080
-Dhttps.proxyHost=hostname
-Dhttps.proxyPort=8080
