Maven 3.1.0 ships bundled with {{{https://www.slf4j.org/api/org/slf4j/simple/SimpleLogger.html}SLF4J simple logger}} and since 3.5.0 {{{../maven-slf4j-provider/}Maven-customized <<<maven-slf4j-provider>>>}},
 but is ready to use other logging implementations: SLF4J is responsible for loading the implementation, referred to as
 {{{http://www.slf4j.org/manual.html#swapping}"SLF4J bindings"}}.
