Thanks Joe, For what it's worth I was able to get rid of that warning and add one of my processors by cleaning up unnecessary dependencies. But that's not going to change the lack of support.
I'm thinking of another way I can avoid updating nifi and the jvm at the same time: could version 1.28 add support for java 21? That might be a big ask but it would make the upgrade path smoother. -Eric On Thu, Dec 12, 2024, 9:06 PM Joe Witt <[email protected]> wrote: > Eric > > No it is not meant to run NiFi 1.x components. > > You could in theory make 2.x components that happen to have certain 1.x > style dependencies but that then is like any other dependency and as a dev > you have to fully know what you are selecting. > > But at a framework level no there is no relationship to nifi 2.x running > or being expected to run nifi 1.x components. > > Thanks > > On Thu, Dec 12, 2024 at 11:32 PM Eric Secules <[email protected]> wrote: > >> Hi all, >> >> I am planning an upgrade to NiFi 2.0 and I'm wondering whether NiFi 2.0 >> is able to run nars built with dependencies on NiFi 1.27.0 and built on >> Java 17?
