Hello all, As announced earlier, the version99 repository of empty artifacts of "commons-logging" will be decommissioned at the end of 2022. For an explanation about this repository see https://www.slf4j.org/faq.html#excludingJCL If your projects are using the http://version99.qos.ch/ repository you need to take remedial action before the end of the year. Remedial action could consist of copying the artifacts from version99.qos.ch to a local repository at your premises. Here is a typical declaration for the version99 repository in a Maven POM file. <repositories> <repository> <id>version99</id> <url>http://version99.qos.ch/</url> </repository> </repositories> Best regards, -- Ceki Gülcü Sponsoring SLF4J/logback/reload4j at https://github.com/sponsors/qos-ch
