It’s most likely the switch to using the aether-connector-okhttp and it not covering a case for which we have no test. Someone submitted this today:
https://github.com/takari/aether-connector-okhttp/pull/7 You using HTTPS and proxy authentication? Knowing what your developer setup with settings.xml would be useful to see. Or take a look at the test cases in the aether-connector-okhttp code and see if your case is covered. If not see if you can make a test that fails for your case and we’ll try to get it fixed up. > On Jan 18, 2016, at 8:15 AM, Steve Cohen <sco...@javactivity.org> wrote: > > I don't see how this could possibly be the issue given my initial description > of the problem: Running from the same workspace on the same machine with > Eclipse Kepler does NOT produce the problem, yet running it from Luna DOES > produce the problem. > > On 01/18/2016 10:08 AM, Matthew Piggott wrote: >> Any chance you have a firewall or anti-virus scanner interfering with the >> connection? >> >> On 18 January 2016 at 10:58, Steve Cohen <sco...@javactivity.org> wrote: >> further info: Switching in Eclipse to use the command line installation of >> Maven on my system, rather than the Embedded version default also makes the >> problem go away.
