Workflow plugin and backward compatibility

[Zoran Regvart]

Hi all,
the workflow plugin starting with Jenkins 1.599 will have support for
build wrappers[1], this would make it prime time to implement support
for workflow in build wrappers such as the Xvfb that I'm maintaining.

How would a build wrapper plugin remain backward compatibility with
older Jenkins installations (well older than 1.599 at least)?

One thing that comes to mind is to register a custom XStream converter
that instantiates SimpleBuildWrapper on Jenkins >= 1.599 or
BuildWrapper otherwise. Is that wise? Could some kind of backward
compatibility support/strategy be implemented in core?

Thanks ;)

Sorry, it is not possible. You can maintain a distinct branch which is
compatible with older core versions and merge unrelated fixes between
the two, if you wish to continue to produce new releases for older
cores. (maven-release-plugin has no trouble releasing from a branch
with major-minor-micro versions.)
