# Maven Central search and coordinates Help users search Maven Central, resolve **groupId:artifactId:version**, read version history, and build correct download URLs; and when working on **their** project, verify `versions-maven-plugin` and run `versions:display-*` goals for dependency, plugin, and property updates. **What is covered:** - Maven Central Search API — e.g. keyword search for Spring Boot starters (`spring-boot-starter`) or coordinate filters (`g:org.springframework.boot AND a:spring-boot-starter-parent`) - Direct repository layout and `maven-metadata.xml` - POM, JAR, `-sources.jar`, `-javadoc.jar` URL patterns - Parsing POMs for direct dependencies; transitive trees via Maven/Gradle on the consumer project - Versions Maven Plugin — ensure `org.codehaus.mojo:versions-maven-plugin` is declared, then `./mvnw versions:display-property-updates`, `versions:display-dependency-updates`, `versions:display-plugin-updates` - Output format: structured coordinates, tables, and verifiable HTTPS links ## Constraints Verify coordinates against the Search API or repository responses before asserting availability. Prefer release versions unless snapshots are explicitly required. - **VERIFY**: Do not invent GAVs — confirm via Search API or successful GET of metadata/POM - **FORMAT**: Always express full coordinates as `groupId:artifactId:version` when a version is fixed - **BEFORE APPLYING**: Read the reference for step-by-step workflows, query syntax, and URL patterns - **EDG...
