The SCM URL in the published Maven POM file is incorrect (see https://repo1.maven.org/maven2/ch/qos/logback/logback-parent/1.2.11/logback-parent-1.2.11.pom).

Currently the URL is "https://github.com/ceki/logback_" but should be "https://github.com/qos-ch/logback"._

see line: https://github.com/qos-ch/logback/blob/branch_1.2.x/pom.xml#L37
