Maven, What Are You Waiting For?!

When building Apache Flink from source using Maven 3.8.6+, two issues arise from HTTP (non-HTTPS) repository references embedded in transitive dependency POMs. Maven 3.8.1+ blocks HTTP repositories for security, causing build failures. A workaround is to override the offending repository URLs in a custom settings.xml. A second issue involves version ranges in dependency declarations: Maven attempts to contact all configured repositories (including blocked HTTP ones), causing a 75-second timeout stall. Solutions include overriding the JBoss repo to HTTPS in settings.xml, using the offline flag, or pinning the dependency version in dependencyManagement. Maven 4 will address the root cause by separating build and consumer POMs, preventing repository pollution from published artifacts.
