Both commands are correct    mvn clean install -Pdev1 mvn clean install -P dev1   The problem is most likely not profile activation  but the profile not accomplishing what you expect it to   It is normal that the command    mvn help active-profiles   does not display the profile  because is does not contain -Pdev1  You could add it to make the profile appear  but it would be pointless because you would be testing maven itself   What you should do is check the profile behavior by doing the following     set activeByDefault to true in the profile configuration  run mvn help active-profiles  to make sure it is effectively activated even without -Pdev1   run mvn install    It should give the same results as before  and therefore confirm that the problem is the profile not doing what you expect

Activation by system properties can be done as follows   lt activation gt       lt property gt           lt name gt foo lt  name gt           lt value gt bar lt  value gt       lt  property gt   lt  activation gt    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

Just remove activation section  I don t know why -Pdev1 doesn t override default false activation  But if you omit this    lt activation gt        lt activeByDefault gt false lt  activeByDefault gt    lt  activation gt    then your profile will be activated only after explicit declaration as -Pdev1

I have encountered this problem and i solved mentioned problem by adding -DprofileIdEnabled true parameter while running mvn cli command    Please run your mvn cli command as   mvn clean install -Pdev1 -DprofileIdEnabled true    In addition to this solution  you don t need to remove activeByDefault settings in your POM mentioned as previouses answer   I hope this answer solve your problem
