* No. 1 aka DEV_MODE seems resolved, the image now has a label that advertises JAVA_DEBUG to enable the "DEVMODE" which works.
* No. 2 aka deployment was agreed upon that we would not require any change in the imported project but the server adapter would publish the approriate files to <deployment-folder>/BOOT-INF/classes since BOOT-INF/classes is the structure that's *ALWAYS* used by the springboot fat-jar packaging.

In regard of No 2 I noticed that if you set the publisher to publish to BOOT-INF/classes everything, source and compilation units alike. Here's what's present in the local deploy folder that then gets sent to the pod:
{code}

>             Project: Tools (JBoss Tools)
>          Issue Type: Feature Request
>          Components: openshift
>    Affects Versions: 4.5.1.Final
>            Reporter: Aurélien Pupier
>            Assignee: Andre Dietisheim
>              Labels: openshift_v3, server_adapter
>             Fix For: 4.5.2.AM3
>
>         Attachments: fuse-on-openshift.zip, project-deployment-assembly.png, spring-boot-demo.zip
>
>
> currently, Springboot jar projects (such as Fuse Integration Services) are rsynced with a zipped jar file.
> The requirements are:
> - rsync unpacked jar
> - rsync without the jar name as folder
> - it will will work only if springboot devtool are included (so maybe need some dialog guiding user to do i in case it is not activated)
> use case "Develop SpringBoot application deployed on OpenShift as any other applications in JBoss Tools":
> - there is a SpringBoot app deployed on OpenShift
> - the developer want to develop evolution of the SpringBoot app
> -- when he/she modifies the project, the application needs to be automatically updated on OpenShift instance
> -- Remote java debug should be available when the OpenShift server adapter is in debug mode.
> Steps:
> # EXEC: create a project in your OpenShift server (ex. camel-ose-springboot)
> # EXEC: Import project within fuse-on-openshift.zip into your workspace
> # EXEC: open launch configuration and change: 
>    ** -Dkubernetes.master= so that it first your cdk instance
>    ** -Dkubernetes.namespace= to the name of the project that you create in step 1.
> # EXEC: run the launch config (that is included in the project), so that the project gets deployed to OpenShift (cdk)
> # ASSERT: your project in OpenShift now contains a service **camel-ose-springboot-xml**, the pod for it is running.
> # EXEC: in OpenShift Explorer: select this service and create a server adapter for it (*Server Adapter..* in the context menu for the service)
> # ASSERT: server adapter is created and is *[started]*
> # EXEC: in OpenShift Explorer: pick *Pod Log...* in the context menu for the pod of your service)
> # ASSERT: pod log is opened in "Console" view and shows an output with random numbers in the end 
> {code}
> simple-route - >>> 455
> simple-route - >>> 695
> simple-route - >>> 935
> {code}
> # EXEC: In Project Explorer: open class MyTransformer and change the transform method
> # ASSERT: "Console" view is opened and shows how the server adapter is publishing the MyTransformer class to the pod
