You cannot modify the basedir, i.e your generated POM has to be at same location with a different name. You might select a name pattern that is ignored by your SCM e.g. pom.tmp. As Jeff said, call Maven like mvn -f pom.tmp However, keep in mind that this does not work in multi-project modules, since the modules will always refer the original parent, unless you overwrite the relativePath element (IIRC you can also define a POM file directly). - Jörg --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@maven.apache.org For additional commands, e-mail: users-h...@maven.apache.org
