Hello, I upgrade liquibase to 2.0. The maven plugin does not use username configuration anymore. Is it an issue? Thanks. Here is the plugin configuration.                       org.liquibase liquibase-maven-plugin ${liquibase-version} process-test-resources ${project.build.outputDirectory}/database/master.xml ${connection-driver} ${connection-url} ${connection-username} ${connection-password} false update ---

It should be.  I’m not a maven user, but the code in AbstractLiquibaseMojo for the username has not changed since 1.9 Nathan ---

It may need to be specified as liquibase.username  Again, not a maven user, but I maybe saw taht somewhere Nathan ---

I had the same issue. Can’t find the article now, but it seems Liquibase maven plugin 2.0.0 has a bug when working with maven 3.x. The username running maven is taking over the username setting in the liquibase plugin. The plugin version 2.0.1 fixes this, not sure if it’s considered stable though. ---

Issue doesn’t seem to be fixed in 2.0.1 for Maven 2 too.  Even when the liquibase verbose mode shows correct username and password they do not get applied. When the same credentials are passed via command line, like mvm liquibase:update -Dliquibase.username=XXX -Dliquibase.password everything works.
