Maven: How do I activate a profile from command line?

Question

This is a snippet from my pom.xml. I tried the following, but the profile was not activated.

mvn clean install -Pdev1
mvn clean install -P dev1

Answer 1

Activation by system properties can be done as follows

    
        foo
        bar
    

And run the mvn build with -D to set system property

mvn clean install -Dfoo=bar

This method also helps select profiles in transitive dependency of project artifacts.
