Spring-cloud-data-flow: how to paste default execution properties on each task execution

Question

I launched spring cloud data flow locally running tow jars: spring-cloud-skipper-server-2.11.1.jar and spring-cloud-dataflow-server-2.11.1.jar

Now I want to add java-opts field but not manually each time I created or launching task. I wanted it was by default. I mean if I launching task I do not need to specify additional options. image

I tried different option on server startup but it is not working...

You can not set the deployment properties on the task definition but you can set them as platform properties per environment. See here for details but TL;DR is if you add something like this to your app config:

spring:
  cloud:
    dataflow:
      task:
        platform:
          local:
            accounts:
              default:
                javaOpts: "--add-opens java.base/sun.nio.ch=ALL-UNNAMED"

You will see this when you launch your tasks:
