@bradflood The pull request pass, the issue in the build is that the sonar cannot be reach. Can anyone do something?

@VinodAnandan I'm looking into some configuration changes for Travis. It appears the SonarCloud Travis addon does not properly invoke the sonar scanner for a pull request not originating within the organization [1] although there are plans to include support for external pull requests [2].

if we want to accept external PRs (recommended), then we'll have to remove the SonarCloud Travis addon and use something similar to what SonarSource does [3]. I've started down that path, but wanted to check with you first before completing. SonarSource has a good example to follow. Should have it ready tomorrow

For security reasons, this advanced feature works only for INTERNAL pull requests. In other words, pull requests built from forks won’t be inspected.
