Facing issue with liquibase plugin enabled in a multi project gradle clean task - which disappears when I dont use this 1.2.1 or 1.2.0 of the plugin

Find below the stacktrace for the error:

I can't think of an explanation for this one.

The Liquibase plugin doesn't do anything with the clean task. The file that Gradle can't delete appears to be the final artifact of your module, and the Liquibase plugin should not be any part of your project's jar.

Usually when a file can't be deleted on a windows system it is either because the file is in use. I'd try to make sure no java processes are running and no file explorer is showing the build directory before running Gradle clean.
