Ruben Porras Campo updated the LSP tooling integration in the eclipse-simrel/simrel.build repository, focusing on migrating to the stable LSP4E 0.27.4 release. He managed build system configuration and dependency management using XML, ensuring the repository location and feature version ranges aligned with the latest tooling standards. This work addressed tooling-compatibility drift, improving build stability and reproducibility for downstream developers. By refining dependency specifications and updating integration points, Ruben enhanced the overall developer experience and contributed to more reliable CI processes. The depth of his work lay in careful alignment of build dependencies to support the upcoming 2025-06 release cycle.
