quarkus: Remote-Dev triggers an entire redeployment(S2I Processor) with OpenShift Extension

Describe the bug (Describe the problem clearly and concisely.) Quarkus remote-dev always triggers an entire redeployment using the S2I processor rather than sending changed code when Quarkus application is deployed to OpenShift using OpenShift extension. This causes removing an existing environment variable(QUARKUS_LAUNCH_DEVMODE=true) in the DeploymentConfig so the remote-dev breaks. Furthermore, it takes quite a time to send changed code rather than using binary deployment.

Expected behavior (Describe the expected behavior clearly and concisely.) Sending only changed code just like using binary build(i.e. oc new-build, oc start-build, oc new-app) when I do livecoding.

Actual behavior (Describe the actual behavior clearly and concisely.) Rebuild an entire project via OpenShift extension then package it for redeployment. after that, the following error is happened when I try to live coding:

2021-01-04 15:46:29,661 ERROR [io.qua.ver.htt.dep.dev.HttpRemoteDevClient] (Remote dev client thread) Remote dev request failed: java.io.IOException: Server did not start a remote dev session at io.quarkus.vertx.http.deployment.devmode.HttpRemoteDevClient$Session.doConnect(HttpRemoteDevClient.java:128) at io.quarkus.vertx.http.deployment.devmode.HttpRemoteDevClient$Session.run(HttpRemoteDevClient.java:169) at java.base/java.lang.Thread.run(Thread.java:832)

2021-01-04 15:46:29,662 ERROR [io.qua.ver.htt.dep.dev.HttpRemoteDevClient] (Remote dev client thread) Connection failed after 10 retries, exiting

This seems to be caused by removing “QUARKUS_LAUNCH_DEVMODE=true”.

To Reproduce

Link to a small reproducer (preferably a Maven project if the issue is not Gradle-specific).

Or attach an archive containing the reproducer to the issue.

Steps to reproduce the behavior:

1. Use a getting-started project like helloword
2. Add an quarkus-openshift extension
3. Add the below configurations

Configuration

quarkus.package.type=mutable-jar
quarkus.live-reload.password=REPLACE_WITH_YOUR_PASSWORD
quarkus.live-reload.url=REPLACE_WITH_YOUR_ROUTE_URL
quarkus.container-image.build=true
quarkus.kubernetes-client.trust-certs=true
quarkus.kubernetes.deployment-target=openshift
quarkus.kubernetes.deploy=true
quarkus.openshift.expose=true

Screenshots (If applicable, add screenshots to help explain your problem.)

Environment (please complete the following information):

• Output of uname -a or ver:
• Output of java -version: OpenJDK 11
• GraalVM version (if different from Java):
• Quarkus version or git rev: 1.10.5.Final
• Build tool (ie. output of mvnw --version or gradlew --version):
