We are running SonarQube (v7.5) internally and running Builds through TFS utilizing the Sonar Tasks. The Prepare Analysis step attempts to determine the branch that is being run, as well tries to determine what the Default Branch is for the repository being built. When attempting to determine that default branch, currently the Task gets a ECONNRESET error when attempting to Call the TFS Server from the build server. This looks like it is caused because our proxy does not handle internal traffic like this, and we bypass the proxy… however this task doesn’t seem to be respecting the windows Proxy settings or NO_PROXY environment variables for this call.
here is an example output with the debug from the build task
