specify pom.xml in mvn command and mix goals of other project

Question

I have multiple questions.

1. Can I specify the pom.xml in mvn command?

2. Can I mix the goals of another project while executing mvn command on current

Answer 1

Just mvn --help would have answered the first question:

 mvn -f otherPomFile.xml

No. You can simple execute the phases for the current project you are in. You can give multiple phases like

mvn clean install site site:deploy
