I am trying to deploy a KNIME Extension from a project that I have not previously worked on. It builds fine in eclipse, but when I generate the update site, the extension fails to load with a bunch of identical errors, one for each node, saying that the factor class could not be loaded because the corresponding plugin bundle could not be activated. I haven’t been able to find any sensible (to me) hints on the web. Does anyone here have any experience with this issue? It is likely that this extension hasn’t been deployed in a couple years, so maybe something in KNIME changed in this time?
