In this paper, we investigate the energy profiles of Continuous Integration (CI) tasks managed by Maven and Gradle. Build systems like Maven and Gradle, with their internal models, provide opportunities for fine-grained classification, which we leverage to study energy-intensive tasks and their associated profile.

Configurable systems become more complex, feature reduction can help focus on essential features while eliminating bloated and unnecessary ones. Although several studies have explored how feature interactions and runtime performance affect energy consumption, none, to our knowledge, have studied the impact of feature reduction. This paper fills this gap. In particular, we investigate how both on-demand and built-in feature reduction affect the energy consumption of configurable systems.
