- GRADLE_LINE_ENDING_REGEXP =
line ending legend: © means a dependency constraint, (n) means not resolved, or (*) means resolved previously, e.g. org.springframework.boot:spring-boot-starter-web:2.1.0.M3 (*) e.g. the “(n)” in “+— my-group:my-name:1.2.3 (n)”

Intentionally overly-simplified regexes to scrape deps from build.gradle (Groovy) and build.gradle.kts (Kotlin) files. To be truly useful bibliothecary would need full Groovy / Kotlin parsers that speaks Gradle, because the Groovy and Kotlin DSLs have many dynamic ways of declaring dependencies.
