Using Designer with project-base-osgi

project-base-osgi has had a recent change to enable it to run on V14

This compiles and works OK but I cannot use Designer 4.5.7 as it produces this error :-

No plugin found for prefix ‘vaadin’ in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo]
available from the repositories [local (/home/paulf/.m2/repository), vaadin-prereleases (https://maven.vaadin.com/vaadin-prereleases), vaadin-snapshots (https://oss.sonatype.org/content/repositories/vaadin-snapshots/), central (https://repo.maven.apache.org/maven2)]
→ [Help 1]

Using this project https://github.com/JulianFeinauer/vaadin-flow-karaf-example I can create views with designer but the Patterns section on the designer pallet does not appear but all other functionality seems OK.

Is there a way I can use the “brilliant new Designer browser techniques” with this flow V14

I have copied this to the pro>Designer forum but there does not seem to be much action there.
