I have successfully run the V12 OSGi starter project in a maven workspace.
After setting up a bnd workspace and copying the flow artifacts from the maven project I have managed to get the project to compile and run but I get errors.
I do not yet understand the boot process for OSGi V12 so any pointers would be very helpful.
What do I need to do to correct…
“Client engine file name has not been resolved during…”
I also think it would be a major development for Vaadin and OSGi if we can create projects in a bndtools environment.
It would also be a great test of the Flow OSGi bundles in a “Pure” OSGi environment. Moving on from an initial reliance on Karaf has been a great move.
If it would be of any benefit, I could set up a github repo with my progress so far.
