[ImageJ-devel] Where are all the plugins?

This was a bug in the Updater (affecting both Fiji and ImageJ2) that has
hopefully been sorted now, thanks to Johannes's efforts. Please let us know
if not.

With any automatic update mechanism, there is a balance between providing
the latest bleeding edge features and bugfixes, and keeping things stable.
Different projects have different philosophies on where along that spectrum
is most appropriate. Some projects, such as the Mozilla Firefox project,
solve the quandary by providing multiple "update channels" depending on the
user's preferences. This is what we eventually hope to do for ImageJ: you
can choose whether to subscribe to release updates only (i.e., stable
channel), or whether you want to get all SNAPSHOT updates (i.e., unstable
from master branch of the codebase).

Personally I think people should need to explicitly subscribe to receive
unstable/SNAPSHOT updates. Otherwise, the people who do not like to be
pestered about updates too frequently would find the constant stream of
updates very annoying. The reliability of the software would also suffer
since not all commits to master are tested as thoroughly as releases are.
However, there *be* a way to subscribe to unstable updates, or else pushing
bugfixes to users who need them in a timely fashion becomes too difficult.

Until we get the multiple channel updates working though, we are erring on
the side of caution with the update site, meaning you must explicitly
download the latest snapshot build ZIP file if you want to try it before
each beta release.

This combined "uber-JAR" is for developers only, as an option, to use with
external integration. For example, CellProfiler uses it, rather than
bundling each of the individual ImageJ2 JAR files. It is not intended for
use with the ImageJ application bundle.

You said you got this sorted, so hopefully it was something easy. If you
had to do anything unintuitive, please let us know; it is supposed to "just
work" like ImageJ1 does.

Curtis
