  The new name better reflects the fact that it also validates artifact transform parameters and other non-property definitions.
- The `ValidateTaskProperties` type is replaced by `ValidatePlugins`.
- The `setClasses()` method is now removed. Use `getClasses().setFrom()` instead.
- The `setClasspath()` method is also removed. use `getClasspath().setFrom()` instead.
