I'm trying to upgrade the logback-classic library from version 1.2.3 to 1.2.8. The patch notes say that all DB related code has been removed, so the main DBAppender class no longer exists in the new version Has anyone found some kind of upgrade guide or know of a workaround solution?

My logback xml configuration file has a custom DB Appender in it and the application failed to build with the following error:Could not create an Appender of type [ch.qos.logback.classic.db.DBAppender]. ch.qos.logback.core.util.DynamicClassLoadingException: Failed to instantiate type ch.qos.logback.classic.db.DBAppender

According to the developer: "The source code is still there. Until this issue is resolved, you can fetch the code from tag 1.2.8 and rebuild. The DBAppender issue is a bit more complex than what people think. As you can imagine, we have a lot on my plate these days but we'll get to it eventually."

As a workaround I have pinned the logback version in my projects gradle file so that I can use the latest version of spring along with the latest version of logback that still supports the DB appender class.
