PROFILE

Marc Schlegel

Marc Schlegel contributed to the com-lihaoyi/mill repository by expanding the Mill build tool’s capabilities in two key areas. He implemented Groovy support, enabling Groovy compilation, JUnit 5 test execution, and Spock testing, while aligning Groovy features with existing Kotlin support for consistency. Marc also integrated Maven project layouts and introduced configuration options for test-only Groovy usage, reducing setup complexity for teams adopting Spock. In a separate feature, he enhanced API documentation by integrating the Openapitools Mill plugin, automating source and documentation generation from OpenAPI specifications. His work demonstrated depth in build tools, Groovy, Scala, and API development.
