Deprecation warning for property jib.container.expandClasspathDependencies

[juergenzimmermann]

Environment:

• Jib version: 2.7.0
• Build tool: Gradle 6.8-rc-1
• OS: Windows 10 Enterprise 2004

Description of the issue:
When I invoke gradle jibDockerBuild I get this deprecation warning:

Property 'jib.container.expandClasspathDependencies' @Input properties with primitive type 'boolean' cannot be @Optional. This behaviour has been deprecated and is scheduled to be removed in Gradle 7.0. See https://docs.gradle.org/6.8-rc-1/userguide/more_about_tasks.html#sec:up_to_date_checks for more details.

Expected behavior:
No warning.

Steps to reproduce:
Just a simple gradle project with the config below.

jib-gradle-plugin Configuration:

jib {
    from {
        image = "gcr.io/distroless/java-debian10:11"
    }
    to {
        image = project.name
    }
}

Log output: see above
