Hi Peter, I found a similar problem when I started working in an implementation of SecurityProvider. My problem was the configuration of the maven-bundle-plugin i wasn't exporting the class. You can check it on the Manifest.MF file inside META-INF on the jar file. Look for the package "org.ucsf.ctakes_auth" in the block "Export-Package"
I solved it setting brooklyn-downstream-parent as parent project. I't is configured by default for exporting the classes built. <parent> <groupId>org.apache.brooklyn</groupId> <artifactId>brooklyn-downstream-parent</artifactId> <version>1.0.0-SNAPSHOT</version> </parent> I hope this helps Juan On Sun, 25 Aug 2019 at 05:08, Peter Abramowitsch <[email protected]> wrote: > Hi All > > I have created a small secrets provider and unit tested it on it's own > first.
