Comment 2 Jesse Glick 2011-06-22 20:50:03 UTC

M2ConfigProvider.getActiveConfiguration was blocked because ProjectProfileHandlerImpl.getLineage, despite supposedly using the offline embedder, was nonetheless making an HTTP connection.

Test case to reproduce

Open attached file in editor and select "POM model" in Navigator. When switching between that and "POM inheritance", there is a noticeable pause, and a network connection is made. This is not true when there is no <repositories> section (at least assuming a mirror is configured for central).
