The Java logging ecosystem is fragmented across Log4J, SLF4J, Logback, Commons Logging, and Log4J 2, with complex bridging relationships that can cause runtime failures like StackOverflowErrors or misrouted log files. Gradle capabilities allow build tools to detect mutually exclusive dependencies at build time rather than runtime. A companion Gradle plugin (dev.jacomet.logging-capabilities) implements this for the logging domain, automatically detecting invalid combinations and offering declarative resolution strategies (e.g., enforceLog4J2()) to ensure only compatible logging libraries end up on the classpath. The concept extends beyond logging to any libraries that change coordinates or exist in multiple incompatible formats. ## Full article daily.dev links to this article rather than hosting it.
