During April 2025, Probitanima focused on modernizing the build infrastructure for the woowacourse/spring-roomescape-admin, -member, and -waiting repositories. They upgraded each module’s build environment to Gradle 8.13, JDK 21, and Spring Boot 3.4.4, aligning the toolchain with current Java ecosystem standards. This work emphasized build environment management and dependency management, aiming to improve security, compatibility, and developer productivity while reducing technical debt. By standardizing the build and runtime environments across multiple repositories, Probitanima enabled faster onboarding and streamlined maintenance. The updates were implemented using Java and Gradle, reflecting a methodical approach to long-term project sustainability.
