logback-classic-db artifactId is mispelled logback-clasisc-db so its deployed under unexpected coordinates at central, see: https://search.maven.org/artifact/ch.qos.logback.db/logback-clasisc-db/1.2.11/jar. The fix is really straightforward, but can provide a PR if its useful.

Also, the ch.qos.logback:logback-core:test-jar dependency seems to be downloading the 1.2.10 version instead of the 1.2.11 one, which is somewhat unexpected too (the logback-db artifacts were released the same day as 1.2.11). This seems to be due to logback-parent-db:1.2.11 setting logback.version to 1.2.10. Again, not that this is wrong, but unexpected.
