How do I pass a string property with spaces to a Spring Cloud Data Flow task?

When I launch a task using the shell, I can't seem to use spaces within a property for my boot application.

task launch my-task --arguments "--app.username=alpha beta gamma"

When my code prints out the value of username, it is alpha and not alpha beta gamma.

My Spring configuration code looks like the following:

@ConfigurationProperties("app")
public class CustomTaskProperties {
private String username;
   ... getters and setters ...
}
Solution

  • You can escape whitespaces by adding single quotes around the property value

    Try this:

    task launch my-task --arguments "--app.username='alpha beta gamma'"
