==== Calling `Task.getConvention()`, `Task.getExtensions()` from a task action

The concept of conventions is outdated and superseded by extensions.
To reflect this in the Gradle API, the following elements are now deprecated:

- link:{javadocPath}/org/gradle/api/Project.html#getConvention--[org.gradle.api.Project.getConvention()]
- `org.gradle.api.internal.HasConvention` (deprecated)

The internal usages of conventions have been also cleaned up (see the deprecated items below).

     * @deprecated The concept of conventions is deprecated. Use extensions if possible.
