Avoid unnecessary task configuration

[3flex]

Pull Request Details

I noticed in a project that uses this plugin that many tasks were created during the configuration phase which seemed unnecessary.

Description

I have applied various techniques to avoid unnecessary task configuration. As written here https://docs.gradle.org/current/userguide/task_configuration_avoidance.html:

The configuration avoidance API avoids configuring tasks if they will not be needed during the course of a build, which can have a significant impact on total configuration time.
