deployment-target=knative not working with Quarkus 1.9

[iocanel]

quarkus.kubernetes.deployment-target=knative not working with Quarkus 1.9, works fine with Quarkus 1.8.2.Final / 1.7.5.Final. Running on OpenShift 4.5 with OpenShift Serverless.

The main message I see in log of the final pod is ERROR Neither $JAVA_MAIN_CLASS nor $JAVA_APP_JAR is set and 0 JARs found in /deployments (1 expected)

The problem I see is that with knative /deployments is still looked at while the path should be /deployments/target

When I switch to quarkus.kubernetes.deployment-target=openshift application starts properly from /deployments/target

reproducer:

oc new-project rsvoboda

rm -rf getting-started
mvn io.quarkus:quarkus-maven-plugin:1.9.0.Final:create \
    -DprojectGroupId=org.acme \
    -DprojectArtifactId=getting-started \
    -DclassName="org.acme.getting.started.GreetingResource" \
    -Dpath="/hello" \
    -Dextensions="openshift, smallrye-health"
cd getting-started

mvn clean package -Dquarkus.kubernetes.deploy=true -Dquarkus-plugin.version=1.8.2.Final -Dquarkus.platform.version=1.8.2.Final

==> application gets available, e.g. http://getting-started-rsvoboda.apps.ocp45.dynamic.quarkus/hello in my case

mvn clean package -Dquarkus.kubernetes.deploy=true

==> application is not available, CrashLoop Error in console

Error from pod:

Tried to set quarkus.s2i.jar-directory and quarkus.openshift.jar-directory but it didn't help in my experiments.
