the scm:export goal for Maven SCM Provider Plugin for IBM CM Synergy is not implemented or not working at all.
I know that Synergy is an old or even obsolete SCM system. But it is still maintained by IBM in its version 7.2.
I can understand why the scm:export has not been implemented and why you did not make evolving the SCM Provider Plugin since a long long time...
But the scm:export would be really useful to me, in order to use it in Continuous Integration Process, involving CM Synergy. Even if CM Synergy is obsolete, it is not dead and widely used in my company (A big Automotive French Manufacturer). And of course, I cannot use scm:checkout + scm:update in place of scm:export.
Maybe, with Synergy 5.x or 6.x, scm:export was impossible to implement. But I think with Synergy 7.2 (The last and only version supported by IBM since april 2016), new option in ccm command line tool can be useful to finally implement scm:export.
I can even do the work and contribute to this task. Just explain how I can do that...
FYI, in the documentation (maven scm:help) scm:export goal is considered as available.
